Hello All: Happy New Year!
Have a Philco 20 that was playing ok, but randomly if I touched a grid cap with a screwdriver. Went to play it the other day and all I can [/b]hear now is a VERY faint hum, no matter what I do with the volume. Took it out of the cabinet and checked the tubes with a TV-7D/U tube tester. They are all strong. Tapped each connection under the chassis with a thin blade screwdriver. Also tapped each grid cap with a screwdriver hoping to hear some scratching through the speaker, but nothing. Jiggled the tubes, etc. Still nothing. Any suggestions as to where to start? THANKS>>>Joe
