Adding AVC to Early Model 70 - Need Opinion
#3

Yes, it can be done. And, no, I am not really satisfied with the results.

I have a schematic around here somewhere which shows the changes I made to a Model 370 Lazyboy that is in my living room. It has an integrated volume control and off-on switch that is pretty much unobtainium. And, as luck would have it, the volume control in mine was destroyed; hence my reason for modifying mine.

Oh, it works okay, but volume is low unless I hook up a longwire antenna, which makes it shine. Early Model 70 sets (unmodified) will pull in lots of signals with a fairly short piece of wire. Not mine, however. And, yes, all paper and electrolytic caps have been replaced, all tubes checked, and it has been thoroughly aligned.

Ed Locker has also done this mod to one of his 70 cathedrals. Perhaps he will chime in with his thoughts.
