Hi Fulham
I have repaired a few AC30s and agree with rapidguitars that the valves can be purchased from Watford valves, hotrox or TubeAmpDoctor (http://www.tubeampdoctor.com/.
Make sure the 2 EL84s are matched. The 3 valves suppliers above offer EL84s as matched pairs. Watford Valves also offer a complete re-valve kit for an AC15.
Hope this helps.
Ade

I have an AC30 Heritage and went to Watford valves. Buy a matched pair for the power valves EL84 and the 12Ax7 for the invertor is best sourced as a matched triode for even push pull . I used Harma and got good results and they are used by Brian May I am told. Good headroom ! Contact the valve supplier if you are unsure and they will advise you. Might want to consider a 5751 in the V1 position for a cleaner sound reducing the gain of one 12AX7 to around 70 % but will need to turn volume up to get volume ! some swear this is a good thing to do ... maybe so with a booster but I am not so sure with the clean shadows thing but I am yest to try it...

Try using 12AY7's(5751's) instead of AX7's Ax break up at level 4 AY's 7-8 volume ,cleaner tone at higher volumes
