I got curious so I emailed tech support at ampeg, got this back:
So I think there might be some false info floating around here. Dont mean this in a "told ya so" kind of way, just trying to keep things right.
Well I don't know how much this is an indication of how much it'll take in raw numbers, but I've lit into a PF115he and PF210he pretty darn hard with an SVT 7 Pro at the music store, and a PF115he will take everything I can give it with a PF350 and not flinch.
But you have to know that it IS possible to blow them with a PF800. The reason is that beyond its RMS wattage, you also have peak wattage. Lightweight amps such as the PF heads don't usually have as much peak wattage as standard solid state and tube amps, but they do usually have some. And it can be enough to blow the cabs if you get an especially big peak from your amp. So if you're going for stupid loud, you should be able to get it but you're still going to have to watch your volume. But they will put out a good amount, make no mistake. Just like I said, if it sounds like the cabs are going to explode, they will.
The SVT-7 is still better, isn't it?
Well don't go nuts in the other direction, eitherYep if nothing else, I've gotten that some common sense applies to the volume. I pressed the tech support guy some more and he's insistent you only need to worry about the RMS power, but he agrees you dont want the peak or limit constantly lighting up, only when you hit the bass harder than normal.
I slightly prefer the 7 Pro over the PF500 myself. I think the tube does make a difference. It's an actual working tube with decent voltage applied to it and not a glory tube. And it's actually 1000w. There was a published test in Bass Gear where it came out to be 750w, but there were also a couple subsequent tests by someone else where it hit like 950, which is close enough for a test to reasonably assume it can hit 1000w. Not that you could tell the difference with your hearing anyway. But it's all about preferences, and I get why some dig the PF500 more.The SVT-7 has a tube and rated at 1000 watts/4ohms, but I recall some talk of it being more like 750 watts/4ohms. That is still plenty loud. Does the tube help the tone much?I have a Marshall MB450H with a tube and a Ashdown MAG 600 with no tube . Both are OK. Yesterday I played a Precision through a new all-tube SVT and 810 at the friendly Guitar Center and liked it a lot.

Now I'm thinking maybe 2x410hlf to get this puppy giving all its got?![]()

Mine gets here this week. I bought a PF410hlf a while back while anticipating getting the PF800. I loved the tone of the original setup I had (pf-500-pf210he) but it never had enough headroom.
They made a more powerful setup and I am back again! I think if the need ever arises, its great to be able to pick up another PF410HLF and have a full stack. Ampeg thought this one through. The PF line serves quite a variety of needs now.
At these bargain prices. Ampeg is definitely giving GK a run for their money now.![]()

1 yep. 2 nope. I'm pretty sure the SVT-410HLF's are 4 ohms so that will kill the amp if you use two. A pair of PN-410HLF's, PF-410's, or SVT-410HE's are 8 ohms each and would more than likely melt a baby's face with that amp.
Good thinking! I'll probably sell my 2 pf210's & pf350 now and grab a pf410hlf, and another later when I get some more cash.
I'm just wondering if this new amp doesnt mean a new cab coming, like a pf410 sealed ... hmm.. LOL
