I've just finished building my first amplifier (PIMETA). Unfortunatley, it doesn't work as it should. When the amp is turned on with no input signal, a lot of noise is heard in the left channel and a little noise in the right channel. Also the right channel buffer is heating up considerably when the amp is turned on with no input signal. The left channel buffer is OK (not hot at all). I replaced the right channel buffer only to find that the new one is still extremely hot to the touch when the amp is on with no input signal. When I plug in my cd player into the amp, all the above symptoms apply, amplified sound is coming from the right channel, and no sound is coming from the left channel (only noise is heard). Buffers were not stacked and there is no bias into class A.
Can anyone help me?
Note: My amp was never on for more than 40 sec. I was afraid something might go wrong with the overheating right buffer.
