I have a CZ-101 whose sound output (in both the headphone jack and the line out) is super, super ultra low and obviously extremely noisy at that level.
I have shorted across my CZ-101's thump relay to test it and no change has been made in sound quality: so it's not the relay. I had supposed that this was the case anyway because both the headphones *and* line out are low, and the relay only handles the line out from my reading of the circuit board diagram.
My inclination is to sell the unit for parts -- I don't have the talent to test for and replace the op-amp, low pass filter, etc.
1. Does anyone have any ideas I should test for before tossing the unit?
2. I'm in the Washington DC area; reselling this for parts is not worth the postage. If you'd like to try your hand at fixing the machine, send me mail! Otherwise up on Craigslist it goes!

Sounds like paid opamps. How much?
