Schematics have typos and aren't always the same chassis revision, in vintage electronics....An original chassis with original factory parts and wiring is just about always going to be more right than the schematic, so it's wise to recap based on what's actually in the set with the paperwork as an extra guide if you get lost or need a 30k feet view of things.

Thanks Tom...yes I'm beginning to understand the typo issue. I do have the Sams and the Radiomuseum schematics and despite being 2 different versions, they do agree on the chassis grounding of the positive side of the 2 paper/phenolic electrolytic caps. I've attached the Sams here and earlier in the thread I attached the RM version, so if you have some time in the next few days (yeah right Chris...Christmas. Who has time!), can you take a quick look and see if they do agree? As always, thanks for your help!

If you look at the edit in my previous post I went to the ETF and looked up the schematics quick and it looks like the positive ground on the cans is correct. I'd still read the can labels to confirm things, but the odds of both Riders and Sam's having it wrong are much lower than only one of them getting it wrong.
