Re-biasing a valve amp.

Hello,

I am looking into replacing the power valves in my Orange Rocker 50 MK II.

I currently have the stock valves in (Ruby Tube EL34's) and I'm looking to chuck in a couple of Sovtek or JJ KT88's. Obviously the biasing will need to be checked etc. Does anyone have any experience with doing this themselves or can someone recommend a good local shop or person that can do it for me. I would normally go to Dennis Marshall, but arsed going all the way to Dunfermline for a ten minute job...

ta!
