This model uses the TOTL 7-tube stereo amplifier using push-pull 6BQ5/EL84, the 9-tube preamplifier is stereo for phono and tape inputs. It has the three tone controls including presence. There is no provision to add FM MPX decoder, being a pre-62 model. The record changer is the standard cobramatic styled VM, not the belt drive model
so I know what I have to do. Like some consoles I see with modifications to add speakers, two wirewound potentiometers poked thru the back cover with some very sloppy external speaker wiring. The amp chassis has charred marks as if something really bad went down
and two output tubes were to air. All caps were original and several resistors were far off. One of the bias pots is cooked as well where I had to fudge cathode resistors to get exactly 135 ohms. Expecting to get the tuner/preamp done this evening so we can test. Odd fact: The amp uses two 12AU7, not 12AX7. The tuner/preamp uses one 12AX7 as the first stage after the volume control.
