Ok After cleaning pots, Checking Resistors All were in spec.. Except the ones listed that I have no clue what they should be.. The Line adjust now works..Went on to checking Voltages.. Some are off But not to far..The filament voltage are close with in the 10% .. But on the high side..
The Others not to bad.
I am using a Fluke 77 Meter with a Resistor to bring the input to the right OHMS/Volt..
The Plate supply voltage is high by 7 volts 150 +/- 5 I read 162
The screen supply voltage high by 10 volts 130 +/- 5 I read 140
the bias control voltage off by 3 volts -39 +/- 1 I read -43
So its working But needs to be calibrated to get voltage in spec..
Only other complaint is the meter sticks when on upper part of scale.. Have to tap it for it to go back down
I do not have a isolation Transformer so I did not do the Mutual Conductance reading test..
Skip..
