Hi there,
Firstly thanks for reading this and giving me the time of day, having read thru this forum anon before im aware im waaayy out of my depth, so both sorry and thanks in advance!
My problem, i have a busted amp - a Marshall AVT150h - which stopped working after a prolonged accidental impedance mismatch (not my fault btw ). The emulated line and headphone outs are still working fine, it is only the speaker output itself which is dead, zilch coming out on all channels. As this is the case i asume the chips and valve are fine. There is no indication of burning or damage on the board and the fuse is fine also.
If any one could offer a suggestion about what component(s) are the problem and how to go about sorting it i will metaphoricly buy you a virtual beer. If the job is an easy one then id like to tackle it myself, if not, then id like to pass it onto someone else with all the parts ordered and necessary information they need.
Thanks!
