The resistor was 48k and changed now 38K but no difference
I have another 57 but baffled by the results with the meter neg lead on 5 cathode here are the two
Screen volts high and neg on all the bias readings ????
tubes plate scr sup bias
57 orig 172 55 0 -13.5
57 used 217 140 0 -8
Went back and took new volts keeping neg on 5 cathode
58 osc 241 108 -42 -2.6
58 If 278 147 0 -4
42 246 262 0 -20
