alpine amp issues

[dhamia]

Ok like an idiot I managed to short out an output transistor which took out the channel

I replaced the irf9540 and irf 540 transistors, 2 of each.

I powered it up and it appeared to work until my in line fuse blew.

The sound became distorted and the transistors were hot.

I have replaced them again, powered up and the fuse blew again. This time I used a 10 amp fuse to minimise damage.

The amp is a mrv1005

Help appreciated thanks

Did u check those small signal transistors?

Would that be the C2682-Y transistors?
q517 and q518?

I already pulled them and the one on the blown channel appears to be slightly out of tolerance

I have t replacements on order
