This has been totally serviced. It has a new Digital Power supply board, of MY DESIGN. 20 times better than the old crap.
It also has the main speaker A terminals replaced with a very nice Banana type screw connectors for either wires, or the
standard Banana plugs.
The old digital board (F-3060) was toast. Brown and fell apart, due to NO HEAT CONVECTION. My new board also offers
an adjustment for the 5 VDC to the radio. It is adjusted for 5.2 VDC right now.
I have replaced 17 capacitors, I also have sheets of paper that show how I test caps, NEVER just swap caps, that is just plain
dumb. I taught electronics, so it's no opinion either, I deal in facts.
It also has new BLUE LEDs in it. The safety relay comes on in about 4 seconds, we are allowed 10 seconds.
All functions work. The radio works good on both AM and FM. The aux and Phono have been tested as well, along with tape
inputs.
In one pic you will see both meters showing the proper Bias voltage, in the other pic it shows the Offset voltage is close to zero.

DO NOT HOOK it to 4 ohm speakers. These are just plain brutal on vintage equipment. READ THE BACK before speaker hookup.
