Questions on capacitor replacement

Looking for advice, recommendations, estimated costs, and DIY instructions for dummies on integrated amplifier refurbishment options. I have a Musical Fidelity A300 that I bought new and have had powered on for about 20 years not including the occasional move or vacation. I recently bought my first tube amp so I thought now would be a good time for a spa treatment for the A300. I’ve had this amp so long it’s like family at this point. Maybe I should build a retirement system for it.
1. Would I be stupid to try this as a DIY project? I’m not a moron or completely uncoordinated, but this seems like the kind of thing that can go horrendously wrong pretty damn quick for the inexperienced.
2. Can you recommend anyone in the Central or Southern California area that knows what they’re doing? I’m trying to avoid shipping it (even though I still have the original box).
I suppose at the very least I should blow it out and maybe clean the volume pots with alcohol.

It’s an easy DIY project, if you know how to solder, and have the right solder tips for it. :)

Make sure you don’t increase the uF too much in power supply caps, but DO get higher temp caps for the main and DO get equal or greater V ratings.

Increasing the uF too much stresses the transformer. Higher temp caps are longer lasting, and making sure you have at least the original V rating will prevent failure.
