dangerboy Posted November 8, 2008 Share Posted November 8, 2008 I've asked this question on TB, but I thought I'd ask you guys too. I've just taken delivery (after quite a tortuous journey) of my new, tiny GK head. These won't be in Europe until next year, so you can bet I'm excited. Anyway, now I need to work out how to convert it to UK voltage. It's built around an ICEpower class D poweramp board (like the shuttle and possibly a few other tiny amps), which has a jumper to control input voltage. So my question is, to get this to work on UK voltage do I just move the jumper from the US voltage point to the UK voltage point, or do I need to do something else too? Any gutshots of Shuttles or other ICEpower based amps set up for UK voltage would probably answer my question pretty quickly. Quote Link to comment Share on other sites More sharing options...
dannybuoy Posted November 8, 2008 Share Posted November 8, 2008 I would guess you just move the jumper, but if nobody comes back at you with a definitive answer, just phone GK, or you can PM Mr Gallien directly through talkbass! I've been looking a these amps myself - you gonna be using live on Wednesday? Quote Link to comment Share on other sites More sharing options...

In fact I'd better go and sort out kitshare for the whole thing! Quote Link to comment Share on other sites More sharing options...
warwickhunt Posted November 8, 2008 Share Posted November 8, 2008 I'm no techie but I'm fairly certain you'd have to change the fuse rating... don't ask me what to coz like I said I'm no techie. Quote Link to comment Share on other sites More sharing options...
The Funk Posted November 8, 2008 Share Posted November 8, 2008 (edited) [url="http://www.gallien.com/preview.html"]Looks very cool[/url]. No idea how to help - my Eden WTX-260 automatically sets itself to the correct voltage and I think the GenzBenz Shuttle has a little switch at the back.

dangerboy Posted November 12, 2008 Author Share Posted November 12, 2008 It did just take one jumper move to make this amp work - thanks to Jason from G-K for the tip-off. Sounds really crisp at low volumes in my flat - I'll update once I get it somewhere that I can crank it! 500W of my favourite sound that I can pick up with my little finger. Heavenly.

Merton Posted November 12, 2008 Share Posted November 12, 2008 The reviews I've seen of this on TB make it my favourite one to get, when I have lots of spare cash... I like the Shuttle but I think I prefer the G-K tone. Let us know how it performs at gigs! Quote Link to comment Share on other sites More sharing options...
RIM Basses Posted December 2, 2008 Share Posted December 2, 2008 Might be getting one of these puppies soon as Marc at Dr bass is now a Dealer! Wahey Quote Link to comment Share on other sites More sharing options...
dangerboy Posted December 2, 2008 Author Share Posted December 2, 2008 They are amazing. Mine is gigging for the first time next week. Quote Link to comment Share on other sites More sharing options...
Delberthot Posted December 2, 2008 Share Posted December 2, 2008 (edited) I'm seriously contemplating one of these as well but then again i was seriously contemplating an all valve amp not that long ago. I love how small and light they are. I'm all for reducing how many trips I need to make from the car to the gig so this would get it down to 2 and would be a lot lighter than my GK 700RB II but more powerful (?) I don't suppose you took a picture of the bit that you move to adjust the voltage for anyone else who is looking into getting one early?

There's a jumper in a holder labelled '110V', so you move it to the one labelled '220V'. Steve Quote Link to comment Share on other sites More sharing options...
eude Posted December 3, 2008 Share Posted December 3, 2008 Any ideas what the UK list is on these bad boys? Very very interested... Cheers, Eude Quote Link to comment Share on other sites More sharing options...
dannybuoy Posted December 3, 2008 Share Posted December 3, 2008 Just under £500 on Thomann at the moment. Quote Link to comment Share on other sites More sharing options...
Delberthot Posted December 3, 2008 Share Posted December 3, 2008 That would probably be a lot less if the $ wasn't so bad just now - $599 over in the US. A couple of months ago that equalled £300, now nearer £400 Quote Link to comment Share on other sites More sharing options...
Dr.Dave Posted December 3, 2008 Share Posted December 3, 2008 The front panel looks much closer to that of the RB amps than it does the current MB series. Does it sound like the RB's rather then the MB's?? I like both - though use an RB400 at the mo , purely because I just couldn't ge the volume I wanted out of my MB150 combo and a cab. I prefer the sound of the RB to be honest , and it's less fiddly to get the sounds I want - I'm well up for the MB2 if it's going to tick all the boxes - ie RB sounds from a MB size Quote Link to comment Share on other sites More sharing options...
lowend Posted January 21, 2009 Share Posted January 21, 2009 Hi, I see there is one of these GK MB2-500 on Evilbay at the moment, converted to 240V. It's not yours Dangerboy is it? Quote Link to comment Share on other sites More sharing options...

dannybuoy Posted January 21, 2009 Share Posted January 21, 2009 Before you hump the bandwagon, check the TB thread out about this amp, looks like plenty of people are having issues ranging from distortion, RF interference, amp overheating and cutting out, etc! Plus they've showcased a new version with the tube pre from the Fusion range at NAMM - I think it had like 3 tubes and 800W in the same piddly sized amp!

dangerboy Posted January 21, 2009 Author Share Posted January 21, 2009 I ain't selling mine. This amp is amazing. No chance I'd want the new one. I hate the sound of tubes. Quote Link to comment Share on other sites More sharing options...
jonlad1 Posted November 22, 2010 Share Posted November 22, 2010 Sorry to bump this, but does anyone have any further info on converting one of these (or any GK head for that matter) to 230/240v? I know you have to move a jumper but do you have to change a fuse too? Cheers Quote Link to comment Share on other sites More sharing options...

As you have doubled the voltage, it'll be best to halve the value of the fuse to maintain the same power limit.

dangerboy Posted December 2, 2010 Author Share Posted December 2, 2010 GK told me to move a jumper. I don't remember if I changed a fuse or not. Quote Link to comment Share on other sites More sharing options...
Dizzy_G Posted December 3, 2010 Share Posted December 3, 2010 I moved my jumper, didn't change the internal fuse, the circuit board is screen printed 5A 250v, that is the fuse that is in it so i left well enough alone. The fuse is time delay too. Anybody get word from GK on this? I would imagine both 110v & 220v use the same internal fuse since it is screen printed (could be wrong).

jonlad1 Posted December 8, 2010 Share Posted December 8, 2010 I'm still looking for an answer. Dizzy - you bought yours overseas and using it in 23/240v country? Quote Link to comment Share on other sites More sharing options...
