Ron's RCA 9T/10K
#3

So I've been plugging away at the 10K chassis.

Capacitors and resistors were jam packed under the chassis. Since RCA documented this set so well, I decided to just go through and remove all of the paper capacitors, all of the resistors, and replace them all.

   

I restuffed all of the paper capacitors, including the single replacement cap, an old Sprague .01 uF unit.

All resistors are new save for the Candohms. I tested both, and both are good. At least they are showing the proper resistances.

I made new wiring harnesses for the speaker cable and for the tuning eye tube.

Then, I turned my attention to the three electrolytics.

I was only able to remove two of the three aluminum electrolytics. Surprisingly, those two still had the boric acid inside in liquid form.

Since both of these were 30 uF, I could not replace with Solen as any such Solen replacement would be way too large for the cans. So I was forced to go with electrolytics. I selected Panasonic replacements.

   

These two are now restuffed, tops glued back on, and I'm waiting for the glue to dry before I polish and reinstall them.

As I had mentioned, I could not remove the 18 uF electrolytic can. The mounting nut would not budge, even after multiple applications of PB Blaster. So I decided to rebuild it in place.

   

I only got as far tonight as cutting the can open and preparing it for restuffing. Since I used electrolytics for the other two cans, I may just stick another Panasonic electrolytic, 22 uF this time, into this can.

But I've managed to get a little ahead of myself. This past weekend, I pulled the 20 uF, 25V electrolytic out of the chassis. It was encased in a fiber box. I removed the guts and filled most of the cavity with hot glue, leaving a small space for the replacement 22 uF, 50V electrolytic as shown below.

   

I still need to reinstall this box under the chassis.

I still have more that needs to be done to the main chassis before I can turn my attention to the Magic Brain (RF unit). I've cleaned the fidelity control & switch. I need to do the same to the other controls on the chassis. And there is a rectangular metal can with some capacitors and resistors encased inside which I need to remove, restuff, and reinstall.
