SVT3PRO HEAD SHUTS DOWN - Calling Techies

phillybill

10 years - no problems, now it starts to sounds slightly distorted, and gradually shut down after a few songs - but it seems to be the power section, since the preamp and DI out still work. Like gradual thermal shutdown. Same rig for 10 years - 410HLF/SVT3. Play classic rock - nothing extreme.
Took it to a repair shop - they found nothing - $140 later, it does the same thing on the last gig - of course I'll have them try again, but thought I would ask on the forum if any of you have seen this problem or know what to look for?

Not sure if this would apply to your SVT3 but it worked for my old Peavey amp many years ago.......

You may want to try buying a small clip-on fan and cooling the amp with it. Your power section could be over-heating.
I'm not sure if the 3PRO has a fan already but if it does you may want to check if it's working. That was the problem with my old Peavey - the fan broke and the output died, but like you I still had the preamp and DI outputs working.
Give it a go anyway.......
Best of luck.
