i have a vox ac 30 which has two output valves. one valve will not work and when i swap them over the other valve won't work so, the valves appear to be fine and the problem is in the circuitry. any ideas as to a solution?

hello there,you say the valves are ok. please do not switch them unless they have the same number,check the pins on the bottom of the valves for a breakage, please try and check where they are pluged in for dirt if you have a meter check to see if power is going to the valves? loose wires, checkthe cicuit for a hair line crack,i hope this will help you with your amp
