A Heathkit IG-72 Signal Generator Part 7 - I think we’re done…
I put the unit back together after replacing the socket. No more arcing, and everything seems to be operational.
The first thing I did with it is cal the AC portion of another device. The stupid thing is already flat at the bottom, I guess that’s to be expected.
I’ll open it back up and dial it way back to keep the osc in it’s linear range. That doesn’t affect the meter cal at all, since the attenuator and oscillator are separate sections.
That’s it…what I thought was an easy fix was kind of an interesting problem. I’ll have my final thoughts and wrapup when I decide the device is not going to do more crazy stuff on me.
