After we were done building Electrical Audio, I made myself useful by jumping at the never ending stream of techwork that comes with a large studio. Over the last 25 years, with help from mentors, and raw exposure to a vast array of unique, boutiqe, as well as ubiquitous studio gear, I developed my skills into a being a decent repair tech, studio and equipment designer. It's also help me, in an odd way with my recording career.
On occasion I am willing to do specific projects ranging from large studio design and installations (console, patchbay, outboard, panels, wiring, etc.) to analog outboard, console, tape machine, and microphone repairs. I also design and build new problem solving gadgets as time allows. Electrical, and many other studios, are littered with random equipment I've built for them. I enjoy doing it almost as much as making records.
Equipment I have lots of experience with...
EMI TG12345 MK2-4 (installed twice, recapped, dozens of repairs, still in charge of upkeep)
Neotek Series I, II, II, Elite, Elan (whatever you can think of)
API (pre legacy consoles and 500 modules, various modification corrections, and repairs)
Neve -most '70s types (installations, repairs, recaps, routing modifications)
Helios, 69 series, and another poop-brown one from the mid '70s (repairs, modifications, schematic corrections)
MCI/Sony 500, 600, MXP3000 series (installations, repairs, upgrades, modifications...)
Sphere Eclipse C mainly (installs repairs, audio fader mod to replace VCA system)
Studer, A80RC, A810, A81X, A820 (2-tk and MCH), A827MCH
Ampex ATR 100s
To a varying extent, I've worked on most of the other professional studio tape machines, but other than the later Otari MTRs, I'll keep my distance...
Most vintage mics including priceless Neumann, Gefell, Telefunken, AKG, Sony, Altec, Schoeps, and Lomo. I'll generally do everything up to the capsule or ribbon.
Most things with analog circuitry.
Here's some tech related videos I did for Electrical Audio.
