Had this thing completely restored and modified. Then the IRS sent new an unexpected bill so sadly it’s gotta go. $8k plus into mods and restoration. More pics coming soon. Here’s the list of work done:
Cleaned existing wiring harness and turret boards. Removed unnecessary wiring and assemblies
New Power Supply
- 10VAC supply replaced with 12VDC supply for LED meter bulbs and VU paging circuit
- 1.5A 48V module to exceed console and phantom power requirements
Direct output circuit designed around Langevin Am457. Replicated PCB layout to maintain snr and sonic characteristics.
Cleaned modules, boards and under transformers.
Original modules recapped and rewired to accept mods
New wire looms from Mogami 2944
Constructed 11 position adjustable input attenuators. 6dB nominal increments.
Direct output boards and transformers mounted on plate in rear of chassis
Passive VU “paging” circuit added
VUs 5 & 6 wired to XLRs for “patchable VU” application - per request
“Backplate” added to rear of chassis for DB25 and XLR I/O as well as power
Replaced rubber parts and rusted screws console wide
Modified reverb send / return circuits on Bus Modules. Gain of return also modified for modern functionality. Added termination resistors and VU trim pots.
Replaced intermittent faders with NOS Duncan faders
Noted out of spec transformers providing lower gain on two modules. Transformers appear to be isolation or “line” transformers. Moved to channels 7 & 8. Direct output circuits tweaked for additional gain on these channels.
All switches flushed and Stabilant 22a added to all panel connectors
VUs calibrated to +12dBu
72hr burn in
