highwayone Posted September 6, 2015 Share Posted September 6, 2015 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 Quote Link to comment Share on other sites More sharing options...
dave74200 Posted September 6, 2015 Share Posted September 6, 2015 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. Quote Link to comment Share on other sites More sharing options...

danbowskill Posted September 6, 2015 Share Posted September 6, 2015 No bids!! Could be the bargain of the year.money saved would buy a nice 4ohm cab Quote Link to comment Share on other sites More sharing options...
skidder652003 Posted September 6, 2015 Share Posted September 6, 2015 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 Quote Link to comment Share on other sites More sharing options...

Thanks[/quote] 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. Quote Link to comment Share on other sites More sharing options...
Bassman Rich Posted September 7, 2015 Share Posted September 7, 2015 ^^^ 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. Quote Link to comment Share on other sites More sharing options...
