Hi to the list!
Anyone got at least one NOS 125@ 450V electrolytic cap for the Drake AC-4
power supply? Would prefer to replace both of them, but if not, one will
have to do.
Please answer direct to me at:
=============================================
Mike -
First, bookmark the DRAKE Home Page operate by WB4HFN
Large number of articles on Drake equipment repair, tips and component
replacement
http://www.wb4hfn.com/DrakeHomePage.htm
The Internet has replaced the inefficiency of searching large paper books
and documents.
That's what GOOGLE and search engines are all about (modern day card
catalogs for the Internet library)

YOU HAVE SEVERAL OPTIONS -- FOR REPLACEMENT.
1. Use the AC-4R replacement board designed by Mike Bryce of SunLight Energy
Systems (available on his web site).
$ 15 plus shipping for the PC board is a bargain.

2. You can "rebuild the capacitor" - like Al Parker, W8UT did for his AC-4.
http://www.wb4hfn.com/DrakeArticles/...Rebuilding.htm
This was done several years ago with R-390A restorations.

Suppliers finally woke up and took note that maybe they should be offering
these for restorers (guitar amps, antique radios, boatanchors, etc.)
3. Both DigiKey and Mouser have a wide selection (snap in/screw in) of
Panasonic, CDE, Mallory, Vishay/Sprague and United Chemi-Con electrolytic
capacitors.
Pages 482 to 486 in Mouser catalog has a wide selection of "cans" (screw,
snap in, 105 degree)

4. Antique Electronic Supply also have NOS and new mfg twist locks

5. CDE is now selling some of their capacitors "on-line" direct to
customers. 105 degree and 500 volt options available
http://www.cornell-dubilier.com/
6. Triode Electronics (here in Chicago) run by Ned Carlson has capacitors
and a wide range of parts

Good luck with it, 73
