Jumping back into this Model 89. My workshop is filling up, and I need to start fixing and selling the sets I don't intend to keep. Label on the back of this one says it is a Code 121. My other 89 that I plan to keep is a Code 123. 
I just went through my Cap stock and pulled everything.
Question: Bakelite Block 4989-W: The 200 ohm resistor: Is a 1 Watt replacement sufficient?

I would just reinstall the original wire loop. It's better than any resistor you could put in there.

The plate current of the 39/44 tube (if the resistor is the one in the Cathode of it in parallel with the cap) is 6mA max, which will make the dissipated power 0.007 W (7mW), which means that any small resistor will do just fine.
If you could re-use the wire resistor that was there - great. Otherwise use any power you have.

This might be a little after the fact but those cloth covered wire wound resistors don't take kindly to flexing or movement. Typically resistance wise they are very stable and should stay in tolerance. Just don't bend it.

figure out what all those squiggly meant.

I wound up replacing the resistor in the bakelite block with a 1 watt I had on hand.
This block and 1 other were done last night.
Electrolytics were replaced today.
I did a quick check of the transformer, some of the coils, and all the resistors.
All checked out, so I decided to turn it on, running it through my variac.
Here's a video I shot during the 1st power up test. All stations came in where they should on the dial.

Last post, showed the radio up and running. I patched a couple pieces of missing wood in the upper part of the grill, did some touch-up work, and gave the cabinet a new coat of toner over the original, and a new grill cloth from Richmond Designs. It went to a new owner just before I left for my trip earlier in January. New owner is really happy, and I'm glad to start thinning out my workshop, and make a little money off the hobby. Here's some glamour shots before it went to its new home.

IF can wire size and Rubber mounts?

| Renovated Radios do carry what you need.
As for the voltage, a wire should be at least 300V-rated.morzh — 11:13 PM |
