Yep. Lowes or Home Depot. You could buy their grommets and trim them. If this is what you want to do.

Trying to finish this 37-650 and after several weeks of not working on it, I am not receiving any stations lower than 710 AM. Tried to start alignment and found AC signal just above 200 volts A/C. Procedure indicates meter should be in the 30 volt range. I have the positive on the plate of one of the audio amp tubes and negative on cathode. Any suggestions as to could be the problem. I don't get ay meter swing when adjusting comparators neither. Thanks

I am not sure how you could get 200V AC across the output tuve, but myself, I always clip my meter to the output xfmr secondary (or speaker's voice coil) and measure volts.
