I have just opened up a really cool Oscilloscope from the late '30's. It's a Thordarson T-11K16 that was made available as a "Build-it-yourself" foundation kit. It has four electrolytic can mount capacitors that I would like to restuff. I actually want to keep this as original appearing as I can due to it's semi-historically significance. It's pretty tight under the chassis for a terminal strip or two so the restuff is definitely is in order. Where can I obtain three radial (axial as a last resort) 10mfd/550V and one radial 10mfd/250V ? Thanks in advance. I want to share pics of this along the way.

Mouser has them. 10µ at either voltage is not hard to find.

If you want it to look original, a re-stuff is a poor proposition, if the original caps are twist lock types. Because new twist locks are available from AES. Even if the originals are not twist locks, you can still mount the new twist locks in a clamp.

Sure. I ordered parts from him just last week. Arrived in less than a week.

Concerning Sal's, the link provided at his web address for the order form doesn't go anywhere on my computer and two emails haven't been replied to. I have ordered from him in the past with complete satisfaction. Strange.

Oh, I see what you mean.
I suppose ordering by sending an email still works. He may not know of the problem.

Those that have ordered from him recently successfully, how did you contact him? He has a small enough minimum order that suits me fine. I could use some help here. Thanks.

I ordered from Sal about six weeks ago. His order form links worked at that time, and I filled out his spreadsheet and sent it to him via the email address on his site.

From his website:

To place a order, send a email to capacitor at tuberadios dot com

My two emails were sent exactly as follows:

capacitor@tuberadios.com

Is this incorrect?

I talked with Sal today and placed my order. He's extremely friendly, professional, and prompt. I hope our postal system pulls through on their end. Once the order arrives, I'll post progress reports. Thanks for all of your help and input.
