Upgrade from heat belching 5U4

[reeferman]

Just curious how many of you have ever replaced 5U4(s) with solid-state rectifiers. As I recall, Philips ECG line was the first to sell a plug in replacement. I started doing it long before that with individual rectifiers. I would take a bad 5U4, bust it up, then solder the rectifiers in. That way a 5U4 could be put back in if desired. I despised the heat those things put out, especially if you had 2 of them sitting on top of the Pwr Xfmr. As I recall, I had to readjust the screens & drives, but usually posed no problem as the set was in for service.
