bassman50 Posted May 12, 2009 Share Posted May 12, 2009 PEAVEY MAX 450 BASS HEAD Just wondering if anyone else has had problems with this Amp when running at 2ohms I have had a new 450 Max just under 12 months when it has started to cut out (Thermal Shut down apparently) the amp generally works the day after having reset itself Next time i used it it blew completely!!! BAck to Peavey for repairs then 1st time I used it after return it blew 15 seconds into the set (Thermal Shutdown again - not completely blown) oh dear - is this a 'Friday afternoon' ampa?? its gone back to Peavey again for checking, unfortunately it works at the moment so that may be tricky Oh yes whats my speaker set up I hear you ask 2x10 Peavey 4 ohm 1x15 Peavey 4 ohm combining in series to 2 ohm load I havent tried the amp on a gig with either speaker on their own. Someone suggested that my speakers may be faulty but I have meter checked all the connections and resistances of the speakers, I also have continued to use my Mk6 Peavey Head at 2ohm in the meantime and it hasnt blown up yet Any ideas?? it might help if I knew that other bassist had similar problems, otherwise I feel a completely new rig might be the only answer I bought the Max450 as a back up for the Mk 6 because I know no-one makes 2ohm amps any more (maybe Im beginning to find out why?? cheers Quote Link to comment Share on other sites More sharing options...

cheddatom Posted May 13, 2009 Share Posted May 13, 2009 I've had the same sort of problem with my Peavey TNT combo. It's always fine the next day. Never had any lasting issues. Quote Link to comment Share on other sites More sharing options...
Mr. Foxen Posted May 13, 2009 Share Posted May 13, 2009 Paralell would be a 2ohm load, series would be 8. Maybe connect them actually in series, so its 8 ohm and see if it works better then. Quote Link to comment Share on other sites More sharing options...
BottomEndian Posted May 13, 2009 Share Posted May 13, 2009 I've had the Max 450 and I've currently got the Max 700. I've always run them at 2 ohms, and never had a problem. They've never shut down unexpectedly. The 450 once fell out of a moving car; took it to rehearsal, plugged it in... perfect. Sturdy and reliable. Sounds like you've got a duffer.

Buzz Posted May 14, 2009 Share Posted May 14, 2009 If it's getting too hot and is indeed thermal shutdowm, how'd you feel about making some holes and putting in a 120mm pc fan? They run at 5 or 12v and it should be relatively easy to fit them. Seems to be looking at the manual that there's no fan on that amp, but if there is one, tried cleaning it?
