Ok, I definitely need some help on this unit. I couldn't find a schematic for this model of Airline, so my friend and I had to go by the values on the caps, resistors, and electrolytics that were in the chassis. It seemed to work, but one major problem has appeared. It seems to have too much bass! Either that or my speaker is junk. It's a pm unit, so wouldn't be too hard to replace, but I still need voltages and the proper impedance to replace the speaker if that is the culprit. So far this $15 bargain is turning out to be a wee bit of an albatross. Oh, it also either has a tube issue or another issue that causes it to cut out from time to time. I might have narrowed that down to the 6SJ7 or its socket.
No matter where you go, there you are.
