I finally got around to restoring the old gal and it works pretty good
except for an annoying chirp on CW. It sounds like the VFO has trouble

Tubes are good and supply voltages look ok. Any ideas? Thanks much and

Hi,

I had a chirpy Apache at one time, and had luck
substituting a 6AH6 for the 6AU6 in the VFO
(both tubes have the same pinouts).
This trick appeared in 73 Magazine in the early 60's.

Check out 'electric radio' and or am international on the google search
engine. The DX-100 has been changed and modified to the high nines and Im
sure you can find some info on it.
