Ampex 350 Mod
Front Panel Control Reassignment:
- Headphone Jack → Hi-Impedence Input jack
- Record Switch → Phantom Power Switch
- Record On Lamp → High Voltage Present Lamp

- Equalization Swith → Phase Reverse Switch
- Mic or Line Input Switch → Mic, Mic with -20 pad, Hi-impedence Input Select Switch

Modifiations are fairly extensive. Older parts that are failing of dubious sonic quality are replaced to give the Ampex 350 channel electronics a new lease on life. Some part values are changed. Front panel controls are reassigned and new functions added, like mic pad.
Power Supply Construction:
When original power supply is missing a replacement power supply is built with correct voltages for modded 350 channel electronics.
