Same here gts.
I've never really gone to component level on panels etc,like you we do the basic meter checks and replaced the transformers if at fault but that's it.
We fit new panel and in some cases upgrade the external sounder also,it's not worth the trouble and TBH safer to fit new,besides our suppliers are good so we get replacements FOC,Honeywell great,cooper brill,tex not so good as can be slow.
I'm only doing this psu because my friends son stupidly opened up the psu looking for a fuse lol,poly fuse in this one and litle did he know the thing has a manufacturers lifetime warranty on it,so he voided that :D.
Expensive psu mate this one so I'm having a go,but normally wouldn't be interested as I've got better things to play with and besides can't really learn something new with psu's.
I've got lots of spare time on my hands these days gts so now I keep myself occupied be learning about things I didn't have the time to learn about when I was working. :) :)
