The Heathkit AG-7 Audio Generator part 5: It’s gonna need everything.
I received some new tubes for the Heathkit AG-7, and that did nothing - so the unit is probably going to need most (if not all) of the parts replaced.
Case in point, this 100kΩ resistor:
But as you can see, the meter tells me that this is actually closer to 700kΩ. Not surprising for a high-value carbon, and a spot check of other components revealed a similar story.
I’d say this thing had a lot of repairs over the years, as there are plenty of mixed component types. So…it gets entirely rebuilt, because it’s going to need it. Stay tuned, I’m going to do this one in stages.
