I powered up and tried to get screen grid voltage reading.
The only way I see to do this was to connect to # 2 wire on terminal strip. which goes to all 3 screens.
Using an dvm. With the volume all way down it reads 14.2 vdc when turning it up I get a steady climb in volts til it gets to about 45v that is about 80% up. Then I lose the signal completly or it drops in volume to just barely audible.
Then I have to turn it down to about halfway and tweek the tuning cap to regain audio signal. I did add resistor to bring up to the 12000k range.
Any help is greatly appreciated on what to check next. Thanks
