valves

I want to buy a spare set of valves for my 5.1. The manual is useless so I am not sure how to get inside the amp to check what valves I need! Can someone let me know what I need to order and any tips for getting inside? Thanks in anticipation.. Al

hi, just wondering if anyone could lend some advice.. i just bought a warwick tubepath 10:1 (off ebay to replace a very unreliable trace elliot head), and seem to be getting quite a lot of noise. does anybody else seem to to have this problem? at first i though it was a grounding...

My Pro-TubeIX needs new valves. Has anybody changed them themself and if so are there any problems or issues I need to know about? Dose anybody recommend specific makes as well? Your tips/recommendations will be greatly received coz i dont have a clue!
