Hi all,
My Chameleon Labs 7720 (silver metal pots version) has intermittent noise (crackle and hiss) in the left channel output, occurring whether the compressor is either inserted or disengaged, and when the unit has no line inputs connected.
I have replaced all 4 DC Regulators, like for like, but the problem remains.
I am now considering replacing all capacitors on the board, and figure I might aswell install higher grade than the stock JH brand aluminum capacitors, unknown brand ceramic disc capacitors, and two unknown brand film caps.
I have spent countless hours looking at GSSL threads in attempt to find solutions, and recommended capacitors, but to no avail.
So, I would be very grateful for responses to the following questions:
1. What could cause intermittent hiss/crackle in the left channel?
2. What is the best solution/product for the upgrade of disc capacitors?
3. Would swapping a 2.2uf 63v +-5% film cap, for one of the same capacitance but higher voltage be sensible (having trouble sourcing 63v)?
4. Are audio grade aluminum capacitors suitable for the main board and side chain?
Any advice would be greatly appreciated.
Thank you.
