"I really don't see how a 0.01uf cap moved from the earthy side to the HT could make the radio squeak?" I agree Trevor, the cap's a snubber to stop back EMF but might also act as a HPF though at a quite high roll off so with a Class A SE OP stage it shouldn't effect anything. The only thing I can think of is the primary windings inductance and cap if connected wrongly (or right) might act as a tank circuit turning the OP valve into an oscillator.
