Hi!
I have build two A30 monoblocks with the Peter Daniel's PCB. In the first month they works fine.
Yesterday I heard in one speaker a strange random noise, sometimes low, sometimes high, sometimes nothing.
Anyway the amplifier works but with this strange noise.
What can be happen?

exact schematic is ?
besides inspection of all solder joints , check all elkos ,especially ones in feedback and Aleph CCS modulation
if not that - replace both input mosfets , or first just mosfet for input CCS
all that counting that you have common supply for both channels , so - because you hear noises in just one channel- PSU is excluded

Is a monoblock (the other channel have her PSU) but not seem PSU noise

check wiring , then check what I wrote in previous post
