[R-390] Rebuilding C551 - BTDT?

[Craig C. Heaton]

Barry,

Just depends on how handy you are with tools, and what's in the tool box.
I've used a dremel tool to cut open the bottom of a C551, all four sides.
Cut off the old wire leads. Then use a wood screw, twist it into the
oil/foil/paper and pull everything out, dry out the insides. Next, use a
small numbered bit to drill a hole into the lugs on the bottom piece that
was cut out with a dremel tool and tap the hole. Gotta use a small drill/tap
or else the drill will cut the lug in half. Use the correct size machine
screw and solder lug on the bottom piece. Solder on new cap, I used a NTE
Mylar found in a local store. Small lengths of heat shrink on caps leads
will help. Insert cap into old C551 body and solder the corners.

Takes more time to write about the dirty deed than to perform the job.

What ever floats your boat, it is your radio. I've got the time and tools.

Craig,

Has anyone rebuilt C551 (the 2uF AGC cap on the IF deck)?  Is it very
difficult?  I'd like to rebuild it as opposed to just putting a replacement
under the deck, but if it's really a pain, then I may just go the easy
route.

Thanks,
