Gallien Krueger MBP115-11 Line voltage info

[Cordwangle]

Just a heads-up for anyone buying a GK MB/MBP cab from USA - which I did a few weeks ago as I was unable to source one (MBP115-11) from any UK outlets.

My cab arrived within a week (well done FedEx) but was 115Vac type; I emailed the relevant fella at Sam Ash, Miami & he just said that I should buy a converter (step-down transformer)..!

I wanted some sort of refund - he offered $25......I refused & we had a few more exchanges.

Then, I decided to open up the amp section of the cab (I'm a qualified electronics engineer btw) to check for a voltage selector & on the PSU/amp board was a jumper enabling either 115 or 230Vac....!  I moved the jumper to 230Vac position & all is good - cab works fine on UK voltage supply.

I hope this info will be of some use to someone finding themselves in a similar situation  :-)

Cheers, Paul

That's useful information.

Now you can claim your $25 too.

So a qualified electronics engineer bought an amp from the USA and EXPECTED IT TO WORK ,AS IS ,IN THE UK???

 

really?

To be fair, some Amps have a multiple voltage input transformers (might have the wrong term here) that enables use across the world without fiddling about in the back of the Amp.

Thanks Cordwangle. Related but not quite OT - as we're due to return to the UK next year, you prompted me to look into my gk mb500 fusion. I bought it here in the US, used, when the pound was doing well and I needed to know if I can convert it or if i need to sell it.

I found two jumpers (blue one and black one) and seemingly obvious alternative "230v" positions - which means I can keep the amp (it will still have the 110v notice printed on the amp body, but I'll just put a sticker on it). Caveat: when I do it, I shall have a good look round to see if I missed anything, and I shall avoid those dangerous-looking capacitors.

I love this forum, great info, banter etc. So 'hope this info helps someone. Should I post it as  separate topic?
