Re: Lock light stays on


 

The waveform you see at TP019 is the straight through leakage of the first VFO, this is normal, but not seeing anything as you tune up in frequency on the megacycle knob strongly suggests your HG is not working.
Because the lock light does come? on , and off , that suggests the selective amplifier is working fine.
The other TP monitors the second VFO, thats the kilocycle tuning, and given your measurements, is working fine. That section is seperate from the section you are dealing with, so at this stage can be ignored.
At this point, I would put my money on the? HG crystal, these can be found cheaply online.
Otherwise, measure the HG transistor voltages. These vary a little, but there should be around 9 volts on the collector, around 1 volt on the Base, and a few millivolts on the emitter for the transistor to oscillate. If these voltages are in the ballpark, the next step is to replace that crystal.
Replacing that crystal should see the old thing running again. Thats when you can realign the second VFO to conform to the drum markings.
