Right then!

With the antenna back in the trees, I returned to the radio bench and finally touched this one with a hot iron, so we are officially underway.

Yesterday I started taking notes on the audio amp and power supply chassis. Then some exploration. The large 40 mfd +40 mfd twist lock was carefully removed with a view to opening and restuffing when the new caps arrive. I probed a few resistors, which seem within tolerance, and started to figure out the wiring to the harness which connects to the main chassis. The hot lines are rubber insulated wire which is falling apart...

As to the big ecap under the chassis, it is riveted in place. Unless I can slide it free, i will just disconnect it and add a new cap to the tag board.

Good fun!

Ed

I don't hold with furniture that talks.
