Mystery Caps Identified
In my tone cap material types comparison, there were a couple vintage caps which I couldn’t identify. I referred to them anonymously as the Yellow Cylinder and the Fat Gray Cylinder.
Today, a kind gentleman by the name of Bill Zumwalt was able to give me the clues I needed to track these old caps down and unmask their true identities. The search keywords I needed were CDE and Mustard!
The Yellow Cylinder is a Type WMF 1S22 Polyester Film capacitor with a 100v rating, from CDE Cornell Dubilier. I guess I didn’t think to search for “CDE” – I thought it was an acronym related to the tolerance!
And the Fat Gray is a Mullard/Phillips Mustard polyester foil/film capacitor with a 630v rating. Apparently these were used in some vintage Vox and Marshall amps, and are quite sought after. Who knew!?
So there you go!

Thanks John, great to know. I’ll be heading out to the electronic warehouse within a few days and I’ll see what they have available –i’ll let you know if anything turns up, RK.

Just googled for “CDE wmf 1S22” and found some on ebay, reasonably priced.
Good luck!

Thanks John, I took a look and went ahead and purchased four of them. I’ll look for the Mullards when I go out to warehouse to pick up materials for a snuffer stick — speaking of which, would you have any idea where I could find the lay out for a Bugera 6262 amp head. I know this is off topic, but I contacted bugera and their not willing give up their schematic’s to customers — don’t figure.
Thanks.

I don’t have any experience with Bugera. You could ask them for a contact # for an authorized repair tech- then contact the tech and see if they’ll give you a copy of the service manual 🙂

Yeah I tried that, they have informed me that it was against their policy and suggested just sending it to them for repair. I wanted to repair it myself as well as up grade the output transformer so that would obviously void the warranty. I just wanted to prepare myself before I went in — once I open her up I sure I’ll figure it out.
Thanks again, RK.
