a guy in Bolton ,Mike Powell I think , who deals with more high end stuff though I haven’t used either and they are not exactly close.
I’ve used Mike Powell a couple of times (I live the other side of the M61, so similar travelling distance/time).
Link to Mike’s website – best to phone him.
Cost to re-cap a 20 year old Arcam power amp was c£90 IIRC. Did a decent job. Trouble is the matching integrated now needs to be done….
Otherwise, if you fancy a trip to Liverpool there’s a decent HiFi shop near Aintree called Do Good Audio. Nice people and they’ve sorted a repair for me (like other hifi shops they outsource their repairs).
