Hi,
I've lurked a little in the past but have now registered in the hope of some free advice.
I'm in the UK and lent my MXR Limiter to a, now ex, friend. It ran from the mains with a US plug. Instead of using a AC-AC Convertor (input 230V, output 110V) this chump used a simple adaptor and as a result the pedal is now dead. Is this a simple repair job or is it fucked forever? I've looked inside and can't see any obvious damage.
Thanks in advance.

was there a fuse installed inside?

I would say your transformer is probably a goner, possibly the diodes for the rectification.

Find a schematic first. Off the top of my head, check all fuses, if no luck then replace the diodes / diode-bridges and voltage regulators in the power supply section.

Hopefully the transformer won't be fried if it was spec'ed well enough.

Thanks for the advice. Checked inside, no visible damage or anything that looks like a fuse to me. Think I need to take this to a repair shop

If you take it to a repair shop, they should be able to fit it with a 220 transformer so this doesn't happen again. Expect it to cost about $30+time.

Took it to Rockers, 5 Denmark St. London. They checked it, sorted the damage, and fitted it with an Electro Harmonix 240>100 AC/DC adaptor. £35 all in, nice job, good people, recommended. Thanks again for the advice above.
