I finally finished changing the paper caps last night. Boy, what an effort! Lots and lots of parts crammed in areas with very little access.
Even though I'd like to keep the big electrolytics original to the set, I elected to restuff the main doubler cap, as I noticed its safety vent had failed. Easy enough to do, and arguably the most important capacitor in the entire set, so it's worth the effort!
The chassis isn't perfect, but it's at least a lot cleaner than it used to be. I pulled and tested all of the tubes - my emissions-only tester isn't great, but can at least weed out duds and tubes with leakage. Fortunately, all of these test well enough I think they'll work as-is.
So, the question: does it work?
It's not perfect, but I didn't screw anything up!
There are a handful of problems I want to fix before I will consider the set good enough to button up and use. Although the video bandwidth seems quite good, its RF sensitivity is quite weak - I can only get a snow-free picture with the local-distant switch set to distant, and with my Sencore VA62's RF output cranked up all the way. The tuner and IF tubes are original, and tested "okay" on my tube tester, but I'll try swapping them out to see if sensitivity improves at all. Also, the sound IF is misaligned - best picture does not produce the best sound, and vice versa. I was really hoping to avoid touching the alignment on this set lacking official instructions, but I am hoping with the schematic and instructions describing similar American B&W sets I can bring it in without getting too in the weeds. Also, although the vertical linearity is fairly good, the control needs to be set to one extreme. I found a handful of drifted carbon resistors in the audio output circuit (30-50%+ out), so I will need to check around in the deflection circuits next. However, the fact it is making a reasonable picture as-is is quite encouraging. I can't wait to watch old movies of the Tokyo Olympics on this thing
Hopefully more soon...
