I've adjusted the regen control. It works fine. Again, there seems to be plenty of gain, just no audio volume. I even have to turn the volume down nearly all the way to keep the stations from overloading the front end. It's just the audio volume that is low. I've replaced the 42 output tube (I actually had an NOS one in stock!), but it made no difference. Could a weak 2nd detector (36) cause this issue, even if the front end gain is good?
