info on bogen
This single channel tube amp was sercviced over the last few days, having power supply filters and bias supply filters replaced.It has also had some tubes replaced. It is now up and running very nicely. All tubes test fine. It uses a pair of 6L6 power tubes in a push-pull format. It also uses a 5U4 rectifier, three 12AT7's, and a single 12AU7. Has inputs for tape, radio, aux and phono. Handles magnetis and ceramic phono cartridges. Cosmetics are fine. It had been sitting for a long time before I picked it up at an estate sale so there was a lot of dust on it. It cleaned up nicely. It was missing one knob and I replaced it with a similar (but not exact) type. I have listened to the amp all afternoon and it has that sweet midrange and treble that you expect from a tube amplifier. It is really nice
now just to get another one

Re: finally
You need to talk to the vintage radio people. A good book is "Electronic Classics" by Andrew Emmerson. Take care, it's easy to reduce value.
karma said:It's cleaned up nicely, but the cord and rca and speaker
terminals are ratty. Should I replace with new, and what's the best way of geting rid of rust on transformers?

nothin wrong with mono -- sometimes even new music sounds better on it.. much less all the great stuff that was recorded on it pre 1960 -- I have mono amd stereo systems -- why listen to hank williams or early basie in stereo ? sometimes you can hear more in mono --it's pure
