The only difference between this and the PC2350 is there are a few less buttons on the pre-amp otherwise this is a H-bridge PS amp looks identical. The board is spread out maybe about 15% wider (Bigger amp), and I'd say this amp is maybe better than the PC2350 since it has 2 power input blocks. Made in Korea sticker, but honestly - could have fooled me. Looks like made in the USA and it has an American flag on the board.
This amp came in with the output driver card solder problem and the power supply pulsing which I've fixed. One of the cards was fixable, but one of the other cards was pretty bad so I replaced it with a parts amp. The amp powers up and idles at about 2A with no DC on speaker terminals.
Unfortunately the amp is stuck in mute.
I removed the two JFets just behind the RCA-Out jacks but that didn't help. The schematic I have shows lots of muting circuits and of course this amp has a bunch (~12) in it as well. There is audio a few of the op-amps but not too far down the path which is telling me mute is happening quite early on I believe. The schematic I have is extremely blurry unfortunately.
Is there a clearer schematic to the one attached, or a better schematic for this amp by chance?

The only muting jfets for the amplifier are the two in each channel between the op-amp and the driver board.
