Ron's RCA T7-5 Electronic Rescue
#2

Preliminary

To remove the chassis from the cabinet, one must remove the knobs.

They simply pull off, right?

Well...they should.

I had to resort to the old string trick to get the three lower knobs off. For the double tuning knob, a combination of string and brute force finally broke them free.

All of the knobs were pretty well rusted onto their respective control shafts.

Having finally removed those stubborn knobs, I unplugged the speaker cable and pulled the chassis.

As you can see, the dial scale has faded to oblivion. Fortunately, Radio Daze sells replacements. I will not invest in one until I know the radio is going to work, however.

Finally, for those of you who wish to follow the bouncing capacitor symbol, here is the complete service manual (warning - large file - 22.2 MB).

I thought I would have to invest in some .047 uF capacitors before I began, but this radio does not use any! It uses .005, .017 (!), .01, 0.1, 0.25, a couple 10 uF electrolytics and one 18 uF electrolytic. Easy. Icon_thumbup

On the other hand...did you take a good look under the chassis? Rubber-covered wiring! Icon_mad Icon_evil Icon_thumbdown Icon_wtf Icon_crazy
