ashevans09 Posted April 7, 2008 Share Posted April 7, 2008 Hello there, About two months ago I bought an American Mesa BB750, and after arriving here I've taken it to a couple of amp techs and shops, all of whom have told me they can't rewire it for UK voltage. I find this pretty staggering to be honest, because as far as I was aware all Mesa's have a dual voltage transformer, and even if they didn't I was told changing it isn't a big deal. Obviously I was wrong. So, here's the thing, I need a bass amp pretty quickly. I'm currently borrowing a rig for gigs and while I'm very grateful to be able to just even use one, it's not the same as your own. I've invested my time and money in this Mesa and I really would like to get it working, so do I just buy a pretty heavy duty step down converter, or can anyone tell me of a tech who will be willing to sort this for me (preferably in the Oxford/London area)? Money isn't an issue here, I just want this sorted. Thanks for the help, guys Ash Quote Link to comment Share on other sites More sharing options...

andy67 Posted April 7, 2008 Share Posted April 7, 2008 speak to member thornybank - I know hes in Edinburgh but he has access to a fantastic tech! Quote Link to comment Share on other sites More sharing options...

chris_b Posted April 7, 2008 Share Posted April 7, 2008 Get yourself a set down transformer and then you won't have to muck about with the amp. They are not big or as expensive as an amp tech and your amp won't be "off the road". Quote Link to comment Share on other sites More sharing options...
The Funk Posted April 8, 2008 Share Posted April 8, 2008 I use a tech called Frank at Angel Music on Denmark Street. First floor above Music Ground. He's a good bloke and he converted my Aguilar from US to UK voltage. Quote Link to comment Share on other sites More sharing options...
warwickhunt Posted April 8, 2008 Share Posted April 8, 2008 I had a wall wart step down transformer for a USA voltage BBE bass pre and I'm sure it cost something like a fiver... is there any reason (current draw etc) why you can't just use one of those?

FWIW, I think a transformer is the way forward. Quote Link to comment Share on other sites More sharing options...
ashevans09 Posted April 8, 2008 Author Share Posted April 8, 2008 Yeah I realise it says nothing on the website, but one of the guys at my local store said that would be the deal. Anyhoo, thanks for the help guys, following up a couple of the suggestions so I'll keep ya posted! Quote Link to comment Share on other sites More sharing options...
ashevans09 Posted April 8, 2008 Author Share Posted April 8, 2008 As I know diddly squat about electronics, would I be looking at replacing the output transformer or the mains transformer? Thanks, Ash Quote Link to comment Share on other sites More sharing options...
Muppet Posted April 8, 2008 Share Posted April 8, 2008 I know a guy at Panic Music (official Ampeg repair centre). He's got some intresting things to say about step down transformers and their use with amps, suffice to say he does not recommend them. I'm no techy so I can't tell you the details but if you are interested then speak to Mike. Saying that, I've a heavy duty stepdown transformer you can have for free if you can collect it from Peterborough. Quote Link to comment Share on other sites More sharing options...
Kiwi Posted April 8, 2008 Share Posted April 8, 2008 The cost of a step down transformer can vary substantially, depending on the power rating it has. I wish I could remember where I got the one I used with my SWR Bass350... ...someone on BW bought it off me. Quote Link to comment Share on other sites More sharing options...

And also that's really kind of you , unfortunately I'm not in a position to collect it, but nevertheless that was stella of ya mate! As I need this amp for friday, I'm buying a stupidly heavy duty step down transformer from a local builders' supplier tomorrow for the short term, and for a long term solution I'm gonna start calling around some of the amp techs mentioned here. Thanks alot guys! Ash Quote Link to comment Share on other sites More sharing options...
