I fully agree with changing the capicators(electrolytics) as they will dry out with age, I would also get NTE replacement output transistors(TO-3) as they can develop leakage also. A good junk box and new Nte transistors will run you a few dollars. Surely cheaper than a new board. I also agree though with the old aspect of "Don't fix what aint broke" Kevin

If I did want to do anything, I would just change the capacitors. I have had an Astron 50 amp supply on for probably 15 or more years and an Elenco 25 amp supply on for about 30 years. The only times they have been off was when I moved or disconnected during thunder storms. They have even been left on during many of the thunder storms.

Only one issue, about 5 years ago while running on generator power, during Hurricane Wilma, an MOV smoked on the AC line. other than that, It's been the heat of my whole operation continuously, 24/7. for almost 20 years....... ....my nickel's worth de Lee
