He brought it in for a service, changed his mind once it'd had a partial re-cap and was all dialled back in.
Probably worth mentioning, if there's anyone else on the forum with one of my builds and it hasn't had a service in over five years, drop me a line. I can advise on the 16 caps that likely need doing if you fancy slinging the solder yourself, or will do it for parts cost + p&p if you can get it to me. About £35 because Mouser US / UK shipping cost.
