Hi folks- so I received my 2 6L6 tubes and put them in. My filament volts ac is at 5.9 vac on pins 2 of both 6l6 tubes. Pin 3 on both tubes in 250 vdc and pin 4 on both tubes in 255 vdc. Pin 5 in -19 vdc on both tubes. I also get -19 vdc at the junction of resistors 134 and 135 and -47 vdc where 140 positive goes to ground. From positive to negative for electro cap 141 I get 295 (should be 385 vdc) and i get 250 vdc from positive to ground (should be 315 vdc). i checked the candolm (part 137) and the original checks right for the resistances - 1k and 4 k. the interesting thing is that I do not get any voltage ac for the filament volts past the 6 l6 tubes - CORRECTED - I do get 5.9 vac but it on pin 7 on all tubes past the 6L6 s- the 6j5 driver at pin 2 shows no volts ac on the meter but the tube filament glows. i do hear some humming from the speaker - when the volume is all the way up and I turn my signal generator to about 600 kc I can hear it on band A which is good - and when I push the lever in on the dial it is muting (and unmuting when i release it) - but i do not get any stations. Any ideas?? -- Andy
