Sorry, I missed the P in your post where it's a stand alone pre. I would just get a small combo amp rather than a power amp and cab unless you want more than just a home practice set up. If you just want to hear it to practice, you can plug it into a stereo system. You can't just plug it into a speaker, you'll need an amp.

Ampeg SVT-II appreciation thread
- Thread starter i_got_a_mohawk
- Start date
A IIp + (any power amp) will not equal a SVT II. The magic is in the power tubes fed from a nice pre, not just the preamp. I also have an SVT III which has the same pre but doesn't sound 3D like the II, even using the same cab, bass, etc.
Mine is just fine for home use. I just turn the volume down.
So I just upgraded my cab stack to a pair of Emperor vented 2x12's and as a result of the new height I'm considering NOT trying to heft my SVT-II on to the top of the stack, instead having it standing up on one end next to the cabs.. I'm a little concerned about heat dissipation, though... understanding that the amp is designed to vent from sides to back. I've got it in an Anvil / Calzone flight case with about 3 inches of empty case in the back. I was thinking about adding a couple of extra cooling fans to the grill plate.
Anyone have any experience with this?

I believe the svt 2 doesn't have any opening on the sides or top or bottom for venting.
The fan I believe sucks air in from the top side of chassis and blows it through the inside of the amp and it blows through spaces around the tubes.
If I am correct, you should be fine with it sitting anyway you want.
Probably best to leave it upright though so the tube heat rises away from tubes.
Extra fans don't hurt either.

My thoughts, too. The extra fans may mitigate the heat rising, but while it may be OK (I don't know for sure), I don't know that I'd want to chance it.
It turns out that both the II and IIPro do have side vents. Larger on the Pro. But that doesn't stop folks from mounting them in tight rack cases. They seem to manage fine.
Bad picture, but I think air is drawn in on the side, down through the chassis and blows up through the holes for the tubes.
If I'm using it home, I sit it on its side and it does just fine. If I play it out, I'll put it on top of the cab and hook up a simple desktop fan.
I have left it on its side on purpose at a gig before to avoid people from putting their drinks on top of it.

I have the SVT IIP and the SVT II head. Both are circa 1989.
The head does sound a bit more like an old 70s version, but the preamp is pretty close in comparison.
Never had any airflow problems with it being mounted in this rack, but I always have a fan setting behind th rig during performances. Hope this helps

You might want to contact Ampeg if you need an answer. That's what I did
Here is what the codes are but there is no X listed
Digit 4 = Country Code where:
U = U.K.
D = domestic U.S.
W = worldwide
Y = Europe
I just looked it up, and even Jerrold Tiers, the chief engineer at Ampeg under SLM, couldn't recall what X stands for.
