Ampeg SVT CL

[highwayone]

Thinking of buying one of these but wondered if it is compatible with my Orange OBC410 as I've read the Ampeg is 2 or 4 ohm and I think my speaker is 8. looking to switch to Ampeg. Any help would be appreciated before I take the plunge! Thanks

I'm afraid it isn't mate. You need a 4 ohm cab with the svt classic. Some will say it's ok, many do it and the actual manual is misleading but these amps should not be used at 8 ohms. It's been rightly described as like smoking; it won't kill your tubes and transformer immediately but it will slowly.

Cheers for that Dave

Good excuse to by another 8ohm speaker to go with your existing one :-)

No bids!! Could be the bargain of the year.money saved would buy a nice 4ohm cab

Deffo get a 4 ohm cab, I got the Ampeg 410 HLF, some say 8 ohms is ok but as said before the head won't like it. As a really good bit of advice, don't go for a far east head, stick to a USA built one

There's a pretty high chance that your OBC410 contains 8 ohm speakers wired series/parallel, in which case changing the wiring to parallel/parallel will make it a 2 ohm cab, and so SVT friendly. Very simple change, easily reversible.

^^^ What Alex said. I did the same with an old Marshall Jubilee 4 x 10 to play my VBA 400 through, only I don't turn it up full.

A few years ago, I did exactly that to an Ashdown 4x10 to run it with an Ampeg B5-r head which could go down to 2ohms.
