New head or new cab or neither???

Hey guys. I got an Ampeg SVT 3 Pro and an Ampeg SVT 610HLF recently and it sounds amazing! Well, two weeks in and I'm starting to have issues. First, the cab has started making a rumbling noise, kinda sounds like a tornado. Then the tube gain pot has become very noisy. Then this past Friday at a gig, on top of the other mentioned issues, another bassist playing it said it was cutting out and there was some crazy noise when I touched the top of the head with my fingers, until I turned off the EQ. OK, long post I know but I want to be thorough. So I called Ampeg and they said the first problem is that the SVT 3 Pro can not power the 610HLF. They said that cab REQUIRES 600 watts. He said that RMS is the required power and said I would be lucky if the speakers or drivers aren't blown. I was unaware of that and if that is the case, that means that I'm under powering my PA. Anyway, so have any of you heard of that and if so, should I upgrade the amp or downgrade to the 410HLF?

Thanks guys!
 
Hmmm... the 4 is 500wRMS/4ohms and the 6 is 600wRMS/4ohms, so I can't see that much difference, and I've never heard of the SVTs being spec'd and matched so closely. I'm not sure they have a head that matches the 6 any better than the 3P.

That said, it sounds like your 3P has some issues. Cross-testing with different amps/cabs/cables might help diagnose it, and it certainly sounds like some sort of circuit problem in the PEQ that deserves a tech visit, but I really don't think it's the match to the cab.
 
The Ampeg phone drone is a maroon. The cab is rated for 600 watts, it doesn't require it. Even with 450 SS Ampeg watts, that shouldn't be an issue. Pre-amp tubes might be an issue, though.

The guy on the phone does not know what he is talking about but it does seem like your amp has issues that need to be resolved. Send it back to Ampeg see if you can get your money back.
 
I did purchase the amp from an authorized dealer, but unfortunately it is past the 30 day return period. There is a manufacturer warranty and they have told me where to take it to get it fixed, but it is still a pain in the rear and a major inconvenience.
