    Hi folks. I'm finishing up a Marantz 2220 rebuild and I was wondering if I should replace the glass bead diodes (H713 and H714) on the amp board, and if so, with what?

    Also, I want to replace the 3 main caps. I recently recapped a 2230 and I replaced the main caps with a 10000 uf and a pair of 6800 ufs. Can I do that here? If not, what should I use?

    AFAIK, those diodes are not particularly failure-prone, so you can leave them as is; if you do want to replace, 1N4148s should work.

    Those replacement values are not likely to be a problem; have used 8200µF/80V (383LX) and 6800µF/63V (GY) in a recent restoration/upgrade project.

    Dingit, I have a hard time getting the replacement caps all standing up as straight and parallel to the edges of the board. Nice for the appearance.
