I have had a couple of Heath SG series signal generators come thru' my shop over the years. I completely redid one (just for the heck of it) in an attempt to make it usable, a model SG8, and it had to have been the absolute worst generator I have ever seen as far as lack of stability. I don't recall any issue with the frequency changing due to the addition or removal of modulation, but then I couldn't keep it on a frequency long enough to do an alignment anyway. I went back to my General bench oscillator ....

EDIT : for the last decade or so I have been using a BK4040A. .... love it !!

Renovated Radios do carry what you need. As for the voltage, a wire should be at least 300V-rated.morzh — 11:13 PM
