Looks as though I'm going in circles, After the alignment all I get are whistles when I try and tune. So I check voltages and I seem to have a problem with the 12SK7 unless it's a misprint. All other voltages are good on the 12SK7 I get
pins 1,3,5 are tied together and go to chassis
pin 2, 7 are heaters I get 23acv and 34acv
pin 4, -.6vdc
pin 6 88vdc
pin 8 83vdc

Print says Pin 3,4 should have 82vdc???
Tired of chasing my tail! ( to old)
