I just finished a Metro 2203 kit I had sitting for awhile. It's my second build and I took my time. I checked all the voltages and bias twice. Everything looks good; biased at around 35.5mA.
There's not even a hiss coming through the speakers. I checked the cab and cable with another amp, all good.
It's not the 470ohm resistor in the PI, either!
Is there a way to check for power at the impedance switch? I was trying to check for 13/15 ohms at the cliff jack and I couldn't get a reading. The speaker cable reads 13.4 ohms from the speaker load.
I accidentally used input jacks on the output; I don't think this is the problem.
Anybody have an idea?
