Thanks. Those are LEDs. Nice part, a little pricey:

I live outside Boston - major snow storm today. Working from home, listening to music for the last 8-9 hours. Sounds awesome.

I am seeing 20 volts at R11 & R12....What is wrong? No smoke....
Could be nothing, depends what your voltage rails are.
One probe..gnd the other at the resistor.
Measure the voltage across R11 & R12.
Red probe connected to +V, black probe to Q3 source/ R11 junction.
Black probe connected to -V, red probe to Q4 source/ R12 junction.
Marra pointed to this earlier.

On one side I have 4.85 & 0.80 on the other....the speaker output is...1.3 volts. I was using old speakers....I have been trying to get this going for along time.
Perhaps this is mV?
