May also be agood idea to change the filter caps while you're in there as I've seen some go bad from the heat generated. Almost everyone of these I've seen has had a power supply failure as the problem.

since I don't like adding long leads and drilling into chassis I tend to put in some Caddock thin films; they are TO-126 with ceramic pads, a 15w rating and short lead spacing that works on the board. They stick up enough to get the heat away; a piece of Al can be bolted on if needed too.

They are $3 each though, and only up to 1k.

i tested all p-sup caps they all checked out good
within tolerance and hold charge well.
but i have some quality 220v 6800uF, in the event that i should need them
i found a bunch of them at a local surplus for .25c apiece.
i grabbed 20 of them.
oh and tedmich, i had a couple of those in my parts bin that were unreadable
i always assumed they were a diode, but a quick continuity check proved that wrong, so i measured res. they are 27.5 ohms (strange) musta been some
milspec application or something. but now i know what they are.
this style would have worked nicely in my application.
