Voltage is present for the oscillator so it is running but turning the slug changes things obviously but no matter where I turn it still got rainbows so going to do voltages again and I’ll post them.so as long as the oscillator is running I don’t have to touch A17

error-

Measurement taken with color killer full CW ( not sure about that ) and tint in center, with clolor bar generator input on tuner.
TV set for normal color operation, it says “short pin 2 of burst amp V21 to ground.

Then to look at the voltage of the phase det pin 1 with a volt meter through a 47k resistor, this is as to not load it down, if no reading, oscillator is not running, adjust A18 to start, then adjust A17 for max reading.

Do NOT skip that step.
If you see a reading at pin 1 V22 through a 47k with pin 2 of burst amp V21 shorted to ground as the procedure says to do, move on to adjust A17 for max reading.

Then go to next step.

What would max reading be because I did use the 47k resistor and It was alittle over 5 volts. Adjust A17 for max voltage?sams says max deflection?
