Instead of using the 4.75KÙ resistors in R2/R3 for the power supply I added a 100KÙ & 2.2KÙ.
stupid mistakes really piss me off. I'd have been baffled all night if I hadn't followed your advice about measuring not only the voltage, but also the resistance. That's what you get when you stay up till 2:00am building your amp I guess

Is it necessary to hook up the 2" hookup wires? Can't you just measure the voltage anywhere on those bridges?
I know mine's wrong right now, but by putting the lead on the multimeter in the v+ & v- holes I get a reading of about +8.7/-0.3. It's not the measurement I'm looking for (resistors all out of sorts & what-not), but at least i'm getting a fairly accurate read.
I'm not trying to question your tutorial Mr. Tangent, I'm just trying to better understand it.

Once all the components are in place, solder two 2" hookup wires to the board, in the holes marked V+ and V- in the annotated image. You should do this on the underside of the board. For the moment, just leave the other ends dangling loose, but don't let them touch while the power is applied. |
