umph

;o if anyone asks you found it on google

err i've got another little giant like the amp in the first picture thats a little worse for wear still not as bad as the ac30, the roost is the worst condition head i've had

take your pick! hope these are useful, i think i have a few more pictures on my camara if you need anymore

do you need a combo? a top of the range valve di would be in your budget range aswell and would yield some great studio tones!

i'd be looking at pre/power set ups for this kinda power!

not all overdrives completely destroy the original tone of the bass.

The cabinet can't be this rare...[/quote] can i ask how you find the tone stack on the marshall? it's one of the few valve heads with a proper active one and i'm doing something similar with the next head i'm building for myself

[quote name='Mr. Foxen' post='961669' date='Sep 19 2010, 10:43 PM']You already know Chambo's do.[/quote] not exactly a production low end amp though is it like the soundcitys / carlsbros

[quote name='thebassman' post='961042' date='Sep 19 2010, 11:39 AM']Modern transformers, like in the 400+, are far more reliable, so unlikely to be this. On my 400+, my tech narrowed it down to the standby switch. It had been blowing fuses for a while. The switch was letting too much current through, he checked it with a multimeter in line. I strongly recommend you don't do this, unless you know what you are doing. Lots of voltage and current!! Anyway a replacement was only £15 from westside.[/quote] If anything the transformers they use in modern valve amps are nowhere near as good as the old ones they used in marshalls / hiwatts / soundcity / laney / carlsbro. find me a modern guitar amp that has transformers as good as partridge!

i use a file and take the top layer off so you can solder to it with no problems..

[quote name='BassBod' post='960937' date='Sep 19 2010, 09:15 AM']I used an Orange stack as backline on a jazz gig last year, and couldn't get clean volume. Tried all the usual gain adjustments, but it seemed to have a low distortion threshold. Looked great though! I was using a fairly high output Alembic Epic, so I'm sure that didn't help.[/quote] ooer, how high is the output from the alembic if you can't get a clean sound? Best place way to get clean sounds out of any amp is master on full and use the gain as a volume control

any reason you want an 18" speaker size doesn't reflect how low it'll go and generally 18's are very ineffiecent. you'd be better going for a pair of 15's or twelves.

[quote name='Huw10' post='959485' date='Sep 17 2010, 02:22 PM']Yeah, according to the back of the amp. 3.15A Right a little update. I've opened the bastard up. I had a wee tap on all the tubes and most of them seemed pretty wacked, but I took the two worst ones out and switched it on. Fuse blows, but it comes on. Progress. So I figured the four new tubes my tech put in should be working fine. I pulled out the 8 old ones and left the four new ones. I switch it on and HUZZAH! It's working, BUT after about 5 mins one of the 4 tubes is glowing super hot, so I switch it off. I figure that tube is prolly pretty much dead now. Any reason why this could happen? I noticed that the tube directly to the right of it of it was not quite in the socket, could this be why? Also, say this is the lay out of the tubes in the amp: t t t t t t t t t t t t t t t t how do the pairs work - like this? 1 2 3 4 5 6 7 8 1 2 3 4 5 6 7 8 or like this? 7 5 3 1 1 3 5 7 8 6 4 2 2 4 6 8 Thanks again![/quote] Are the plates glowing red? What year is your one i've seen the mesa 400+'s wired both ways. Does it blow fuses without ANY valves in? I think it may be time to take it back to your tech.

[quote name='Anders' post='960462' date='Sep 18 2010, 03:14 PM']They don't have the same sound though,so if you like the Orange AD200MK3 it's not certain you will like the tonalpossibillities or sound of the Matamp GT200.The Matamp doesn't have a mid level and the Orange has meetier and deeper bass imo.You might be able to tell them to make the bass more full when ordering the Matamp but then you would get a little lower output.Atleast that's what they told me. The GT200 isn't on their homepage no,and i don't understand that either.[/quote] tone stack in the matamp is much more flexible if you know how to use it. The orange is also voiced for more low mids, so it'll generally sound like theres more bass going on. Matamp are technophobes best way about it is phoning jeff up and having a bit of a chat

[quote name='Mr. Foxen' post='960286' date='Sep 18 2010, 11:39 AM']Bit fo a rare and interesting item, I'd rather you didn't mess with it, because I want it. I'll swap/part ex for my stripped one, which needs a refinish anyway.[/quote] +1 it's always a shame to do something like this to a rare item

it should be okay as long as you don't crank the power amp to much

[quote name='howdoesitgoagain' post='960229' date='Sep 18 2010, 10:40 AM']Excellent suggestion, I thought of something similar but was shouted down by a mate as it would be sacrilegious but what does he know .. My wife has sort of persuaded me to keep the thing, it looks scary and fits in with our bands style [ ogres mostly ] .. I will have a chat with our pa guy about suitable speakers, baffles and porting. It is a big box, do you think I might get lynched if I chopped it in half and had two Marshall cabs [/quote] don't cut it in half, i've seen far to many attempts at this, it always looks terrible

buy a muff if you want heavily compressed fuzz

did you use the correct value of fuse? The new valves may have been pulling far to much current and taken the fuse.

i don't think you'd be able to fit 4X15" speakers into a 4X12 marshall cab are you sure it's not always been a 4 by 15?

it'll do 200watts clean - its a 200watt amp. 200watts is more than loud enough to gig with IMO

[quote name='RhysP' post='955114' date='Sep 13 2010, 05:55 PM']My brother has got one - he's been offered stupid money for it but he won't sell it. God knows why, it sounds like a piece of sh*t.[/quote] haha yeah, i love the looks of them and they do an absolute killer over the top fuzz sound if you get lucky and it's bias'd right i totally wouldn't pay what they're worth for one though

The special designed transformers are overdimensioned and all materials carefully selected to perform at a maximum level - at all times. haha i love marketing mumbo jumbo, why didn't they just put over speced? Do respect them though for understating the clean wattage as opposed to claiming it'll do way more like some other companys like to do.

do want an original tone bender
