I note that the circuit diagram posted by the OP in post #64 differs from that in post #21. The circuit in post #21 gives the value of C704 as 0.01uF. The circuit in post #64 gives the value of C704 as 0.022uF. There is also an extra capacitor C705. It's very difficult to read the value of C704 from the pictures. Perhaps the OP could advise?
As the OP is in Canada I would suggest that "Just Radios" would be a good place to obtain 0.01uF (10nF) or 0.022 (22nF) caps to replace C704 and possibly C703, but unfortunately there's a minimum order charge.
