Ron's RCA T7-5 Electronic Rescue
#38

Saturday's Progress, Part 4

There was no grommet in the chassis where the speaker cable came through, which likely contributed to the demise of the original cable.

There is one there now.

I replaced some above-chassis wiring, three resistors, and two mica caps. I also cleaned the top of the chassis as best as I could using a can of the orange hand cleaner with pumice. It wasn't really rusty, but was very dirty/grimy/grungy.

I removed another electrolytic can as well. But try as I might, I could not get the nut of the third electrolytic to budge...so I made an executive decision to rebuild that can in place.

Here's how the top of the chassis now looks:

Most of the attaching screws for the coil/IF transformer cans are missing in the photo above. They have been sitting in Evapo-Rust overnight, along with the grid cap connectors. After their Evapo-Rust bath, I will reattach those screws and lockwashers.

Here's how the bottom of the chassis now looks:

I'm seeing the light at the end of the tunnel on this one. I still need to do the following:

Attach the wires of the new speaker cable to the proper points under the chassis
Replace the two-section Candohm
Replace one more paper cap
Restuff all three electrolytic cans
Add a new AC cord
Replace another wire or three
Do something about the broken-off Fahnestock clip/Phenolic insulator for the antenna terminal

...and that should be it other than the dial scale. It looks like the dial pointer is going to be fun to remove...not. It may very well be rusted in place. I'll try some PB Blaster and see if that will help.
