New to forum-mark 3 maintenance

[Boogiemk3]

I am the original owner of a black stripe Mark III (serial#17443)(build date-7/86). I have only changed tubes as required and was wondering if there is other maintenance needed as the amp is almost thirty years old.

Sometimes some of the big blue capacitors need to be replaced before they start leaking. They usually start leaking when that amp goes through extended periods of time of no KSE, so if you use the amp frequently, they should be fine (mine are), but they do make me nervous since theyre nearly 30 years old.

What brand capacitor and where to buy from. Thanks for the reply.
