I agree - it looks pretty good. Mine was a complete mess and the more I looked into it the worse it became.

Yours looks pretty tidy. I would be inclined to pull the board off the heatsink and go over all the solder joints. If the pins even 'look' a little tarnished it is painful - but cheap - to replace them.

Does not look too bad, Rob. These usually look like burnt out bird nests. All the connectors are STILL connectors - no direct soldering. Some of the fuse holders look tarnished. This would be repairable - most likely replace the fuse holders.

If it works, then I'd leave it for now.
