    Right now I have a SVTCL Tube head and I'm debating on switching over to something solid state. A local guys has a used SVT-400T for $200 but I was looking at getting a new PF-350, anyone know which would be the better choice?
    This would all run though SVT810E

    I personally would rather have the PF350. The 400T hasn't been made for years, which always gives me the willies when it comes to replacement parts.
  3. I've had a chance to try a couple of the older Ampeg S.S. amps and wasn't at all impressed with either of them. At one point , I had a chance to A-B a 350 H against my old Peavey Mark 6. The Peavey won that one hands down and the 350 H didn't hold a candle to my SVT Classic.
    If you like the SVT ,the PF350 will come as close as anything to that sound. The PF 500 and the PF 800 are even closer. I would avoid the 400 T , the 350 H and 450 H series. Didn't like the sound I got from either of them. Also ,the B2R and the B4R are the same basic amp as the 350 H and the 450 H only in a rack mount set up. I also agree with Jimmy M (even though his brain may be a bit addled by the Florida heat , mosquitoes and the fact that he probably has had to climb a tree or two to escape alligator attacks ;)) about parts availability and repairs on the older Ampeg stuff.

  4. The PF-800, if you can financially swing it. To be honest though...I'm considering trading my PF-800 for an SVT-3 Pro. I like solid state, hybrids too, but I remain unconvinced with Ampeg's version of Class D.
  5. I used a 400T for 15 years or so, and it worked and sounded great.
    I did replace the fan because it got loud. Pretty heavy amp but indestructible.

    If I go for the PF-800, how much can the SVT810E handle, I could only run it on mono right? That's how I run it now, but if I'm putting 800watts though it - it has to be through both top and bottom speakers (groups of speakers 4 top and 4 on the bottom) at the same time right?

    Nope. You can run the 810e either way. The PF800 will see a 4 ohm load whether you run each half of the cab separately or together. And the 810e can handle 800w without farting out, and won't blow unless you hit it with 1200w.

    I would take a 400T that's still in decent shape, and gig the hell out of it. The PF-350 would be my backup.
