Voltage measured across 3 and 6 on the amplifier board is 11.64 DC
Voltage measured across 1 and 2 on the oscillator board is 24.6 rms
All the capacitors checked ok on the amplifier board. Should C1 be 1uf? On the circuit diagram it looks to be marked 1.99uf.
I will check the oscillator board this afternoon.
