[R-390] Longmont Audio Labs AF Deck

[Dan Martin]

I, too, had a Longmont deck years ago. Thy were quite the rage among many R-390A folks back then. Mine sounded great and worked fine - until it didn’t. I went to the diode load and an outboard preamp and amp and liked that even better. So much so I never did any troubleshooting on the Longmont deck. It might still be around here somewhere.

I have not tested the AF deck. It has the stock plug in electrolytics and appears as later version with 6DJ8 tube. Output tube is 6360 into a push pull transformer. The AF deck is not a pristine later model but an earlier model, decent condition and the work look neatly done.   Thanks,Byron W5FH ______________________________________________________________
