FIXED! Following up on suggestions from Tony Fishpool and from Roy Morgan, I put a 10 ohm resistor between the two supply lines and put 100 uF caps to ground at either end of the resistor. I can now operate the receiver at high AF gain (no problem running a speaker) without the KLUDGE of two power supplies. The RX sounds great. I will soon match it up with the equally awesome Tuna Tin 2 for 1976 QRP EXTRAVAGANZA.
