Heelo all,
I borrowed this amp from a friend to do some recording with, and in exchange she asked me to change the broken channel toggle switch. I did this and it works fine, but in taking it apart, i unwittingly knocked one of the power amp valves (el84) loose, and when i switched it on, it made a horrible sound and i discovered one of the el84s had died. Before i took it apart, everything was fine.
So...i bought a pair of el84s and fitted them in. Now when i switch the amp on, all the tubes (power amp and preamp) light up, but i am getting no sound whatsoever.
I have tried various leads and cabs and whatnot, but nothing works. Would the fact that its not been biased to the new tubes make it not output any sound?
I have also briefly looked inside for any blown fuses, but couldn't spot any..
Can anyone point me into the direction of what might have gone wrong? Am i looking at an expensive repair job?
Thankfully my friend is very understanding
