Peavey and other amps: 110v to 220v - Is a simple rewiring a

Dag Wolf · Post by **Dag Wolf** » 8 Sep 2000 7:19 am

I hope somebody here can anwer this. I just brought back a Mosvalve 500 from the USA and got ready to spend quite a few money in a new power transformer.

I did send an e-mail to genz-benz as a shot in the dark and it seems that a simple rewiring is all it takes to convert this amp to 220v. If this is right - is it the same with Peavey amps? if so it seems like sellers of used equipment in the USA will have a whole bunch of buyers here in Europe.

Thanks, Dag

It depends on the amp. Some amps come with a "dual-primary" transformer, and others don't. If you have a dual primary, it's a piece of cake to convert it. A tech can look at the schematic, and tell. But sometimes, you'll lose the "polarity switch" feature when converting an amp.[This message was edited by Donny Hinson on 08 September 2000 at 01:51 PM.]

Mike Brown told me that hum could be a problem, since the amps and their transformators were designed to use a 60 Hz cycle, while we in Europe use a 50 Hz cycle.

Hi Dag,
I really enjoyed your twin steels at the Convention!
BTW,If anyone in Norway is looking for an excellent steel,I have an Emmons LeGrande III/II D-10 for sale here in Finland.

Hey Olli, it was nice talking with you while we had a cigarette outside the St. Louis airport. I look forward to seeing you again when we have more time to chat.

Thanks Olli, with the US dollar going sky high compare to the Euro you might consider to sell it in the USA. I think it`s really hard to sell a steel over here when you talk about close to new D-10. Players don`t seem to wanna spend the money it`s really worth.

Have a good one, Dag.[This message was edited by Dag Wolf on 12 September 2000 at 03:55 AM.]

I`m still working with this matter. I got the schematics for rewiring the Mosvalve but blew the fuse. For those who are interested I`ll notify the progress in this thread.

Thanks ,Dag

I have imported two Nashville 400s and had new transformers fitted and they work perfectly well in the UK. The earthing proved to be a bit of a problem but my man has managed to get rid of the earth loop by sorting out the earthing insulation within each amp.

I have now brought in a Session 2000 and a PX300 which my man is working on. I will let you know if we get them working in which case I may well bring in some more.

When I used to build Evans amplifiers all of the transformers had four primary windings that were engineered for USA, UK, Europe, and Japan, all at the right freq.; just retap (rewire on a BTS) is all that was needed. Check with the Evans WEB site and see what they have available now.

BTW; great pickin in St. Louis Dag!

Evans and Webb both make amps for the European market.
