Anyone have a schematic for this amp or one similar? Or knowledge of how the muting circuit works in it?

Amp has audio signal on driver card. Power light is on, no protect, everything seems to be fine other than its not releasing muting. The relays do not click.

I've tested the D1302 muting transistor that controls the 2 muting relays. All 3 pins have high ohms readings (while in the circuit). Using the neg rail as the black probe reference, the base has 0.000v (or basically neg rail), the collector has 4.10v (above neg rail), and the emitter has 0.023v (above neg rail)...
