Servicing and repair recommendations in the UK

[pioneergear]

Hi,

Unfortunately I suck at electronics.
I'm looking for someone to service and repair an intermittent problem on my Pioneer M90a.
I live in the London area but don't mind going further afield to get it to someone trusted by forum members and known for getting the job done to a high standard.

Can those in the UK provide any solid recommendations?

Thanks in advance.

Have you managed to find anyone in or around London that repairs vintage amp and does a proper job?
I would also interested in someone that does tuner alignment as these specialists seem quite hard to find due to the expensive equipment involved.
