I’ve just finished recapping & testing this TC equaliser / preamp. It’s a useful, musical-sounding eq with a decent amount (20 dB) of gain in hand. Each channel has two bands of EQ, ±20 dB gain control & bypass switch
This 1220 is in nice condition and still has all the original knobs & switches. It’s in the shop now
This has the usual TC Electronic upside-down PCB
Simple EQ section with no electrolytic capacitors
Power supply and input / output on one board, recapped with Panasonic caps, bipolar for the audio section. PSU bypass caps are on the other side of the board
