Quote from: Hawk on February 19, 2015, 09:20:55 AMNo on both counts. We do not know where any W connections are going except where shown. W13&15 are shown going to outputs, the others not. Suggest ignoring them.
Shows both having the speaker outputs at W12,13,14,15.
...In my mind these speaker outs should come off pin 7 and 8 as they are the neg, pos signal.
The output IC shown on page 3 is the power amp. The other circuit with W12 thru W14 is not.
Pins 7&8 are +/- supplies, not signal.
The output IC data sheet may be helpful.
