Changing valves
« on: June 03, 2007, 11:24:52 AM »
Well i think th etime has come...my Laney VC30 doesent sound the way it did so i think the valves need changing. Ive never done this before and havent realy got a clue about how to go about it. Could any of you point me in the right direction please?

that amp uses EL84s in cathode bias so no need to rebias - just pop a new set in there.

give Watford Valves or Hotrox a call, tell them what amp you've got and see what they suggest.  from current production EL84s I'd say to go for some JJ/Teslas.
