Quadraverb replacement capacitors
« on: August 14, 2007, 02:33:54 PM »
I'm trying to repair a Quadraverb which is missing capacitors in positions C1, C2 and C45. C1 and C2 are connected to a TL084 chip. The input right and left channels feed into the + inputs of the TL084 and the output and - inputs are tied together, connecting through C1 and C2 to the input volume control. I'm not sure yet where C45 goes but it may be linked to the circuit which controls the clipping LEDs on the front panel which aren't working at the moment.

If you've got the lid off your Quadraverb at the moment, I'd be grateful for any advice on the values for these three capacitors.

C1 and C2 are 4.7uf electrolytics, - leads facing the op-amp.  C45 appears to be a 100n just like C52 over by the advance and bypass footswitch jacks.

Thank you very much. I'll have a go repairing the unit this weekend.
