Anyone built their own guitar amp?

Hi,

I've got a solid-state Marshall amp that's knackered...something got spiled on it (I think), and now it's gone totally nuts and sometimes works, sometimes doesn't, sometimes just buzzes...makes a funny smell too.

Anyway...the speaker unit (12" - not sure of the rest of the spec) and cabinet fine, as are the knobs and sockets and what not. I was gonna chuck it, but I thought I might have a bash at knocking up my own amp.

Anyone here done it? How hard is it? I can solder, and I know a few bits about electronics...as alot of you probably know I'm the sort of person who can pick up the theory quickly if nothing else..

Curently got a ECC83 one valve amp going - working on the reverb. There's loads of plans etc on the web - I'll post up a few makers of the bits you need to buy (transformers, speakers and the like) when I can find them...

Mate of mine did. It was back in 1974, so not a lot of help reallySorry

I understood that Marshall UK carried spares for all their amps - might be cheaper to just fix it?

ok i presume its a 1x12 combo.you say its solid state.so its probably worth the thin end of fuck all.if it didnt say marshall then worth even less.tell us what the amp is.as has been said there are many diagrams out there to build your own propper valve amp that will do everything you want.if you know what you are doing you could make an amp that would cost you £500 for under £100.if you are a bit crap you could make an amp that just gets hot and makes a loud buzzing sound.what are you after and how much effort are you going to put in?

if summat got spilled on it, which mine has in the past, yank out the plug in connections and clean them on the amp, dont forget to unplug the fucker first thocould also be crappy leads or your guitartry a different guitar and leads and see what happens with the ampI would suspect its the guitar, check the connections from a new lead to guitar, Marshall amps need a good kicking to fuck em up, its prolly a simple thing like a crap lead or a pickup on the guitar thats gone looseHTH

oooh, whilst we're on this subject I've an 30W solid state acoustic amp with a really poor reverb function. Spring job on the bottom. Any of you clever bodgers suggest a modified plan for this, or failing that, a maker of a halfway decent reverb spring please?

If you don't use one of these, then you are an amateur who needs to take up another hobbie.Yours for £10k.

To be honest, You're as well getting a JCM90... I always hated Marshall but I swapped a 7 string for a 900 head and I love it, All valve, All Marshall. you get get them for Peanuts on Ebay because everyone wants the JCM800 and earlier. Mine is one of the first 900's and has had KT66 valves put in it instead of the usual EL34's. For what they're fetching you might as well just get a 'Proper' valve marshall and be done with it.My 2p worth

I've just clicked on that wreckset link & followed over to your spot on myspace. WTF are those two on the youtube clip? That's just made the hairs on the back of my head stand up & my hand shake a bit. Sorry about dissing your fav tipple-I bought some Jim Beam black in the end, thereby ignoring most of the advice..

Which two? The guitars? That's me and Mikey... I'm the one with the Yankee's top on swearing at the engineer through the mic The song is Exit Wound... It's on the player at the top, Albeit an older version.
