I reside in Bristol. So far I have had it serviced by an independant guy called Jesse James and later on by Justin @ [url="http://www.heronmusic.co.uk/"]Heron Music[/url].

Justin is Subthumper on here. I send ampeg stuff to him, because I don't like working on it, despite the rep, the stuff is plain badly made. Throwing valves at a problem amp is rarely the way, problem is elsewhere, if its more than about 15 years old, its probably capacitors, ampeg way underspecced them and they die pretty early. finding the problem is fun because of the way ampeg make the amps, can't run them open to figure whats going on without specialist looms, forcing you to go to Ampeg approved techs who just bulk replace entire PCBs and charge you accordingly.
