Scanning a Service Manual
Jeff, I am not sure where you are located. I am in CA (in the east bay). If you need help on the scanning, I can help. I worked at ARC document solutions before retiring in 2017: https://www.e-arc.com

Great info. If you can get the bearings/bushes in hand first, it might be an idea to go for it. You can always buy the magnet wire easily. The fun is getting it working like when it came originally!

If it is a bush bearing, is it not possible to turn one out using phosphor bronze? If you are near a machine shop, it might be an idea to show them and see how much they would charge.

Message from your fearless (foolish?) leader
Hoping and praying that Mrs. Tillman will recover fast. We all take the other half for granted and this sort of thing makes us think hard! Take things slow and try not to get overloaded yourself.

Greg is correct. I had a reply from Paul on Nextdoor (I have an account) and since the overwhelming nature of this project, he prefers to stay with the FB contact procedure. Definitely no personal ema

465 55v regulated filter cap type.
The space there is very tight. I had to manipulate/bend the leads and put heat shrink on them to get it in there. I doubt an axial cap of sufficient value can be fitted there as it might be too tall.

In search of holdoff pot for 2235
Last night I was trying to locate it on the schematic but fell asleep after a little time! Can you email me a picture of the broken part? If you are in the US, I might be able to help you repair it.

It should be 50k. Best is to check the two end tags with a meter. You may have to un-solder the wires.

A resurrected 465 parts scope.
I had this 465M for over 20 years now. Got it for $100 at a swap meet. Never used it that much but while troubleshooting my friend's guitar amp, blew the EHT module by leaving it ON overnight accident

Of course! After a few drinks and too much to eat, at 1:30 AM while being a one finger typist, with the computer accepting anything I type, viper sounds like wiper anyway! I am glad I did not type Via

Happy new year guys! C 1374 is a possible culprit. You can always replace it and give it a try. If not, you could solder a couple of leads to the viper and the 50 volt ends of the pot and bring them a
