Hello. I bought a ZK-3002 amplifier, but it has a very high noise level, is it possible to fix it somehow. The capacitor C1 has been removed in my model (this correction was made by the manufacturer to solve the shutdown problem). There is especially a lot of noise when used with the ZK PRO 1 timbre block from the same manufacturer.
I just built dual mono amp with these and I’ve got same issue. One of mine was quiet for few days then bam white noise. I have another one here I’m going g to try its brand new ver 4. See how that one is.
