Hi,
After I turned off the amp, there is always some DC value at the binding posts, that is without connecting to any speaker though.
I tried some white resistors to drain it while measuring it as well the DC value go back up to 50mV as soon as the white resistor is disconnected from the binding posts.
I remember I read something like breeder resistor intalled in the PSU to drain power. How do I intall it and how to calculate power and ohm value for the resistors? I am using CLC unregulated power supply for a Class A amp.
Thanks in advance,
Chris

Hi Chris,
This looks like a neat little circuit. It's a bit more then a simple resistor. The advantage is that the resistor only works when powering off the unit.
