Model 66b Low Volume
#1

Replaced 3 electrolytic caps, 6 paper caps and 6 resistors. All tubes test good. Followed the Rider’s alignment instructions. Volume is weak using an 8 ft antenna wire. Touching a screwdriver to the top of the 6A7 tube, 1st detector oscillator, causes a significant increase in volume on the AM band (not on the SW band.) Any suggestions for increasing the volume?
