2. Timeline

Date Event Source
1995 Boto Design plans, Sheet A-5.1 "Electrical Design Specifications". Note 1: a single-phase tech-power panel, "orange" isolated-ground (IG) receptacles, a separate green ground conductor per branch back to a ground buss panel in the machine rooms, and no lighting or HVAC on tech power. Note 2: "Provide 5' solid copper ground rods in each machine room", a 2" copper buss on isolated bushings, and 3/4" conduit with a #2 conductor from each buss bar to the ground rod, then to the electrical room "for future connection to secondary neutral ground point of isolation transformer." [F] ~/trc-electrical/source/imessage/2026-08-03-handoff-img0-sheetA5.1-notes.png
2024-05-24 Commercial property inspection by Stuart Huff. Service: "120/240 volts", 200/400 A, and the form ticks both 3-phase and single-phase. Grounding: the visible grounding goes to a cold-water pipe and a ground rod and "appears serviceable". Outlets: "There are outlets that did not have grounding when tested." Panels: Zinsco panels, and subpanels with missing knock-outs. Wiring: a mix of cloth and plastic. [F] ~/trc-electrical/source/files/2024-06-13-property-inspection-1660-9th-spero-midler.pdf
2024-09 RodCo quote #24 offered a 3-phase 240V to 208/120V transformer for the main-stage distribution box, for "isolation from noise due to lighting and equipment" ($3,330). It also offered new circuits for Studio B and the Podcast room. Invoice #54 bills a new sub panel, alley outlets, the EV charger and the sauna, but not the transformer. [F] The transformer was never installed. [I] ~/trc-electrical/source/files/2024-09-*
2025-08-10 Ari: "The entire building just flickered multiple times." [F] chat.db 826852
2025-08-29 Greg to Jolby Kimble: "clients today had some issues with buzzing on different channels, a low freq electrical humm on a channel, and some channels not being usable" in the mixing room. [F] chat.db 833039
2025-10-23 There is buzz on the livestream. Alex: "It's almost certainly the lights causing the buzz." Greg: "I still hear buzz on the stream." Alex: "Should be fixed." [F] chat.db 850917-850937
2025-10-24 Greg to Farzad, before the outdoor electrical work: "make sure whatever we do properly connects with the ground system and has no chance of causing a buzz in any of the lines of the studio." Farzad: "Sure.. NP" and "I need to finish all the outside electrical work … before the rainy season." [F] chat.db 851201-851212
2025-11-03 Farzad: the gym and kitchen outlet circuits "were lacking neutral wire so [re]wired all the way back to the panel." Jacob, on 11/4: "yes there is a neutral wire now." [F] chat.db 853302, 853534
2025-12-01 Jacob: "crazy buzz from the lobby speakers after Farzad's guys came in … Something to do with the sub but Devin's gunna fix it." [F] chat.db 863180-863181
2026-01-12 An SCE crew worked in the alley behind the building (4 kV "Surfrider" circuit). [F] Any link to the grounding fault is unproven. [I] ~/trc-electrical/source/files/2026-01-12-sce-crew-tailboard-alley.jpg
2026-01-22 03:07 First ground test. Alex: "Jeremy and I just used a ground tester in the live room and every single outlet in there has an open ground. Considering the issues we've been having with buzzes this would be a great explanation." [F] chat.db 877629
2026-01-22 Alex: "The qsc sub that we got repaired a couple months ago is broken again … likely cause is dirty power." [F] Thai, asked for a fix: "Sounds like an electrician thing." [F] chat.db 877698, 877711-877712
2026-01-22 Lifelog: someone says the building is "attached to a ground … it must have just dried out … they sometimes have to water the grounding unit." [R] ~/Documents/Limitless AI/4-6-26 export/data-export_2026-04-07_07-51-54/lifelogs/2026/01/22/2026-01-22_23h25m04s_A-casual-intimate-conversation.md
2026-01-23 Greg emailed Brian Banks: "we're having a grounding issue … a ground that may need to get watered." Brian replied: "The grounding post used to be located on the side of the building next to the meter … not sure if it's still there. You might need to move some of your outdoor installations to find it." [F] Gmail 19be8dfaba4a939b, 19beaf58dab7fc88
2026-01-31 Greg forwarded Brian's reply to Alex. [F] Gmail 19c163c5e79cf9f5
2026-03-14 Lifelog, a staff meeting: "the room is not grounded … the actual ground stick got dried up." Greg: "I haven't blocked the electric being fixed … But it hasn't been done." [R] .../2026/03/14/2026-03-15_00h18m04s_...md
~2026-03-16 Alex and Eric tested the panel [R, from the lifelog]. The findings: the orange outlets are the audio outlets, and they read open ground. The lights and the audio are on the same panel. Channels 2, 20 and 22 were down or crossing. Channel 2 had been out for months, and 20 and 22 went out after New Year. Bypassing the Catapult splitter behind the desk fixed channel 2. Thai said that when the split was built, "they like just pressed a bunch of the ground switches and then it kind of … magically worked." Eric was unsure whether the open ground is intentional. ~/Documents/Limitless AI/4-6-26 export/data-export_2026-04-07_04-11-54/lifelogs/2026/03/18/2026-03-19_03h59m45s_Discussion-about-electrical-issues-in-a-studio.md
2026-03-19 Alex texted Greg: "Thai said there was an intermittent buzz since the day they set it up … likely not the catapult directly since it's a passive system. So I'm going to prioritize fixing the audio/ lights panel connection, and then solve the grounding." [F] chat.db 892005
2026-03-20 Lifelog, a team meeting: "an open ground, which is potentially intentional, … according to Eric … Then there's a separate issue which is that the audio and the stage lights are on the same panel." Someone adds that in a session "the lights were on and … slowly but surely, a little bit more buzz." [R] .../2026/03/20/2026-03-20_20h15m07s_...md
2026-03-31 / 04-01 Alex asked Farzad to come in "regarding an electrical grounding issue." Farzad replied: "let's talk tomorrow around noon, need to understand the background." [F] No record of a visit exists. chat.db 895114, 895479
2026-06-01 Alex: "Buzz solved by simply pushing in the ground lift button on the DI box" (the Omni piano). [F] chat.db 911261
2026-06-22 Elijah's session recap: "issues with noise on the Stage Right snake. Had to move around ports and swap cables." [F] Gmail 19ef21d2098a3451
2026-07-28 Team meeting. Greg assigned Elijah his first task: "figure out the electrical grounding in the live room," with Alex briefing him. The staff view was that "the potential right now is in the splitter that's behind the console in the blue splitters." The group discussed the ground stake and watering it. "We don't know where it is." [F, transcript] ~/claude-grid/public/responses/2026-07-28-team-meeting-transcript.html
2026-07-31 Greg shared Dennis the electrician: $50/hr, $200 minimum per visit, +1 747-248-9954. [F] chat.db 926767
2026-08-03 Jacob found a "grounding unit" by the neighbors, then a "New Jon discovery": a fitting "connected to the electrical box outside that goes to the roof." [F] Elijah posted "Studio Grounding Handoff" (3 pp) to TRC Core +, then sent an UPDATED version with a corrected photo C. Its text: "There is no copper wire … on either outside ro[d]." [F] chat.db 927428-927458. PDF: ~/trc-electrical/source/imessage/2026-08-03-elijah-studio-grounding-handoff.pdf
2026-08-12 to 09-02 Insurance inspection by Carlos Sanchez for Fullsteam / RT Specialty. It required replacing the Zinsco panel and removing "Tape on circuit breakers." The carrier waived the Zinsco replacement on 8/20. Greg, 9/2: "The tape on the breaker is handled." The photos show a Square D panel with breakers labeled "OUTDOOR", "STAGE LIGHTS" and "…CH", one breaker taped with a "DO NOT TOUCH" label, and main Zinsco gear labeled 240 V. [F, from the email sweep] Gmail thread 19ffd05a0c3b5b51; ~/trc-electrical/source/email/2026-08-13-insurance-inspection-rec-photos.pdf
2026-09-04 Elijah, planning the rehearsal-room re-cable: loose PMC/HS8 cables are "probably causing some of the electrical hum." An Apollo sharing a power source with the TV causes "a slight digital static sound." [F] This is a different room and a different mechanism from the live-room buzz. [I] chat.db 936498
2026-09-06 Jon Q: "the rain tripped the breaker" (washing machine / lounge). [F] chat.db 936762
2026-09-09 Greg sent a link to his electrician scope page, https://power.gregspero.com/electrician.html. That page covers demand control, not grounding. [F] Greg to Thai: "could you talk with Elijah about the buzz thing we're having in the live room on a few channels?" Thai: "Not sure I can offer any more help than I have before? Call whenever." [F] Elijah asked about turning off the "lighting breaker" at night. Greg: "Turn lighting breaker off. Just keep computer on." [F] chat.db 937875, 938050-938057, 938079-938081
2026-09-12 Johnny Cesene's post-mortem: "a buzz in channel 26 on the trident in the mixing room," with a video (IMG_7139.MOV). Greg, 9/18: "with our engineering side now." [F] Gmail 1a0a1405f178a678, 1a0b4c54bf114ef4
2026-09-14 Elijah: "I just met with an electrician … he was on the original team that built this place in 1995 … could come in … proper deep inspection, but it would cost like at least 250 so maybe we just save that as like a last resort." [F] chat.db 939491 (TRC Director Chat)
2026-09-15 A calendar "Deadline board" lists: "Exit signs installed by Fri 9/18 (electrician)"; "Rain-tripping breaker: same visit, 9/18"; "Ground rods copper conductor: same visit, by 9/25". Owner: Taji. [F] Calendar event 2lit940qaimr09aa4m4fh66pts
2026-09-16 Elijah to Greg: "If you have a moment today to look through options for watering the ground stake." [F] No reply is in iMessage. chat.db 940141
2026-09-17 Elijah sent a photo of a Chauvet Hurricane Haze 2D fog machine on a towel beside a power strip and cables: "causing a ton of water for fog juice to spil[l] on the carpet and on cables and outlets." [F] chat.db 940421, ~/trc-electrical/source/imessage/2026-09-17-elijah-fog-juice-outlets.jpg
2026-09-18 Farzad to Taji: "Elijah is in the process of setting up an appt w/ Abe a lic. Electrician I work with." [F] Greg to Brian Banks: "the rain tripped a breaker that took out the lounge TV and speakers." [F] chat.db 940598; Gmail 1a0b4c62b32ea1e6
2026-09-21 22:46 Elijah's latest test report (quoted in full in section 3). [F] chat.db 941340
2026-09-21 23:07 Greg's direction to Elijah: (1) use the studio schematic and graph every connection tested; (2) mark every cable tested individually and strip layers down to the most direct connection, because only a buzz that persists then proves it is power; (3) if it is electrical, find out why it hits only those channels by building "the full MAP of the electrical of the studio … what appliance is plugged into what plug … all the way to the root of the power supply." Greg then corrected himself: the engineering.gregspero.com link "was the old engineering director application… I meant to send the schematic of the studio … Alex knows it." [F] chat.db 941356-941371
2026-09-24 13:07 Elijah: "This is great, I'll start on this list asap." [F] What the "list" refers to is not in iMessage. It may be an email or a message on another channel. [I] chat.db 941792

3. What has been measured

Reading Result
Hot to neutral about 121 V, solid, on every outlet
Hot to ground low, floating, drifts when touched
Neutral to ground floating 30 to 60 V, unstable
Plug-in tester "Open ground", center lamp only

4. Hypotheses and their status

# Hypothesis Proposed by Status
H1 The ground rod has "dried out" and needs watering Landlord, via Greg's memory; Eric; Greg (1/22, 3/19, 7/28, 9/16) Open, never tried. The rod was never located with certainty. [I] Watering a rod does not fix a missing conductor, and the handoff shows clamps with no conductor attached.
H2 The technical-ground electrode was never connected ("future connection") or has corroded Elijah, handoff 8/3 Strongest documented hypothesis, unverified. It is backed by the 1995 Note 2 wording, the absent conductor on both outside rods, and every IG outlet failing alike. The plans put the tech rods inside the machine rooms, so the outdoor rod Elijah photographed is probably the service electrode rather than the tech rod. That is an inference.
H3 Audio and stage lights share a panel, so lighting noise gets onto the audio Alex/Eric in March; Greg "had a feeling" Reported, not documented. No panel schedule backs it. The insurance photo shows "STAGE LIGHTS" and "OUTDOOR" on one Square D panel. The handoff says Farzad's electrician "reports a grounding conductor is already landed in the subpanel labeled 'Outdoor / Stage Lights'" [R]. The 1995 spec forbade lighting on tech power.
H4 The Catapult splitter or its ground-lift switches cause it Alex/Eric in March; staff view on 7/28 Partly supported, partly contradicted. Bypassing it fixed channel 2 in March [R]. Thai says it is passive. Elijah on 9/21 says it is "not a panel or stage box issue."
H5 The lights cause the buzz Alex, 10/23/25; team, 3/20 Consistent with H3; untested in isolation.
H6 Cabling or dressing near monitors Elijah, 9/4 Applies to the rehearsal room only.
H7 Farzad's 2025 outdoor work disturbed grounding [I] from the timing: Greg's 10/24/25 warning, the 11/25 neutral rewire, the 12/1/25 lobby buzz, the 1/22/26 open-ground test Unexamined. No evidence either way.
H8 Open ground is intentional (IG design) Eric [R] [I] IG receptacles still need an equipment ground back to a ground bus. An "open ground" reading on a plug-in tester means no ground path at all, which is a shock hazard (the handoff says the same).
