How to mod a poweramp from USA (110v) to Europe/AUS 240V?

[kev]

Hi guys,

Having great difficulty finding a vht 2/50/2 in the used market over here at the moment, so i'm wondering if it is a realistic task to grab one from the states and have a mod done on it to make it play good with our electrics. I dont fancy running it with a convertor block really.

Thanks muchly!

Power transformer swap. Other than that, no.

Depends on the amp. Some have transformers that can be easily switched between 110V/240V even if there isn't a switch.

This is true, sometimes they have different hookups etc inside the amp. Take a look at a schematic and you might be able to find out.

Thanks guys, yeh Jarkko, thats what i'm really hoping for I'll see what research I can do in the meantime and hopefully someone might chime in here who has done it themselves.

Here's what I was told by a dude who has done it here (VHT 2/90/2)

" it has a multi tap transformer that requires 2 wires to be de-soldered & soldered together to make it 240volt, a replacement fan & a new fuse "

 

[kev]

Oooh tasty. Any idea who it was dude?

 

[Jarkko Mattheiszen]

Pretty much any good electrician could do it if you provided the schems

 

[Sloan]

SWEET, you win brah.

Yep just fix the wiring and cut the fuse size in half and you should be good to go. The fan must run off the mains side of the trans, so you'd just have to switch it out with a 240v AC one.

I'm pretty sure Steve would gladly tell you what needs to be done if you email him- support@fryette.com

 

[kev]

yeah tis great stuff! I did email steve before about it, but he didnt respond unfortunately. I'll end him another one and hopefully he'll have chance to respond with a schematic. Will let you know how I get on : )

 

[Wolfeman]

He won't give out schematics, he's very anal about that. You'll never find them online either. But it should be simple enough without them.

 

[kev]

Yep thats definitely fair enough Eric. Ive googled everywhere so far, and am waiting to be allowed to post a thread on the fryette forum. For some reason support@fryette.com is dead as a dodo at the mo which doesnt help lol. All I want is an idiots guide to doing the mod really. I can solder ok, but know jack all about electronics any more.

 

[Sloan]

Dammit, if a company won't give out scems, they need to man up. Hell with it, get a Peavey, best cust service I've ever experienced y'all. YALL.

 

[sprack]

Have to agree that Peavey's support has been very good.

it depends on the transformers, most of transformers have windings that can do 110/240 voltages, if I'm not wrong usually there's one end for 110 and one for 240.

 

[kev]

Right then, im completely internetted out on this one. Fuck.

 

[Wolfeman]

Once you get it, I can easily help you out. All it will take is a multimeter on your end, and a few pictures and we can get it set up properly.

Eric, you're an absolute gent dude. Should be here in a week or 2. Would we avoid killing me as well? lol. One question though, would I need a step down transformer to power the amp when doing the tests?

That would work the best. Even if you have 'something' that puts out AC lower than 120v, that would work as well (something like a variac).
