Oh, it works okay, but volume is low unless I hook up a longwire antenna, which makes it shine.

It might be that the model 70 does not have enough overall gain to support an avc operation, being only a seven tube set and especially with no multi-function tubes. I suppose I could replace the 24 detector tube with a 55 tube and install a conventional diode detector and triode amplifier as was used in later designs with the 6Q7 or 6SQ7. But then I would have to change out the tube socket also. That is not an option which is easily reversible.

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

Yes, it would be interesting to get Ed's take on this, being that he has done a conversion on one.

I would also be very interested in any else's opinion on this topic.

Ed
