Nice work, it's surprising how many faults you can find just by having a look at the thing, and checking which bits are getting hot that shouldn't be.

I'm fortunate that I can just drop into South Island Components if I need stuff, but even through E14 or RS shipping from the UK can be surprisingly quick.
