RCA R-73 RESTORATION
#81

Tracing the wires and soldering in the caps was not much fun, the wires being discolored and routed at the bottom of the chassis, plus tied up with a cable twine, so pulling the wire was not really possible....at least the first one.

But....I defeated itm and today put the last four caps into it.
It is not really beautiful, as I had to put 5 or 6 caps on the same solder lug on the resistor board, as this is the only solder post connected to the common negative after the filter choke (field coil). And the caps are aluminum cans and yellow tubulars. Even if good brands. But it works. Taking off and opening that can was a bit too much involved, and I felt reluctant to disassemble the whole chassis RF part to gain access to the tabs, which require huge leverage to be unbent.

Then I simply plugged it in and joyfully heard nothing....that is, no hum; however moving the volum pot wiper produced a bit of rustling sound, so I tuned the dial and heard the locla station, clear, no hum. Touched the antenna, the station became loud. I say, it is good.

Now, I have to make the dial move - no friction between the shaft (smooth metal) and the twine. I might put some rosin on it, or change it altogether.
Then the tune-up.
Not sure it is coming today, but maybe next weekend....

PS> Rosin helped. Found where I stashed it and rubbed it against the cord. Seems to work. Also wiping the shaft with isopropyl dry alcohol first improved things a bit too.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
