@@signalsandbits I bought a PCM60 from eBay and the unit was not working as it should. The description from the seller claimed everything worked on the unit. I powered it on and it was noisy and the unit appeared to have blown out out twice…I had to repower my Furman power strip- then the unit stopped passing signal. I put in bypass and signal started passing again… now It only passes audio in bypass … all led lights work and it sounds clean in bypass mode. Can you fix this? Is this something you are familiar with? Do you have an estimated repair cost?
