Amplifier Discussion / Roland JC120 HELP!!
July 23, 2014, 12:49:45 PM
So we lost power on this bad boy, checked the fuse and it was bad.  Pulled the chassis the two 6amp fuses were also blown.

No resistors on the board look back, did take my meter and test several.   Anyone have any similar experiences?


Thanks

I've got a Trademark 60 that sounds amazing!!!  However after 15 minutes she shuts down.

1) Caps?
2) OP Amps?
3) Cold Solder joints?
4) OT?

Any one who can point me in the right direction would be awarded with two thumbs up :dbtu:
