I decided to go through the whole hassle of retolexing my so far favorite Marshall 4x12. It`s a late 70ies cab with G12-65 speakers. The tolex had tears and stains and there was a hole in the fornt grill cloth. And of course, the cab came without the Marshall logo and casters. Getting rid of all...

So Anthony from the 33 Workshop in Belgium did fix two of my Boogie amps previous techs were not able to. One was a Triaxis that did not respond when changing settings and the other one was a Recto RevF modded by Voodoo amps which after years developped humming because of problems in the channel...

and finally some guys are giving him some pushback, which is good. Can`t imagine how many less experienced guitarist were missled by his BS-clickbait videos.

Ok guys, I have two Marshall 4x12 cabs that were originally loaded with g12-65 speakers. One has the later, big recessed input terminal, the other the earlier small one. The early one has a really nice response and feel in the bass and low mids register and it pushes a lot of air with my JCM800...

Hi, what would be the best potentiometer choice for a resonance mod in a JCM800 2203 style circuit? I played around with fixed values and liked the 220k resistor and 0.033uF or 0.022uF cap combination, but haven`t tried any other resistor values. What would you suggest as a pot value? 500K or...

AFAIK Celitic Frost was one of the inspirations for a lot of bands of the 80ies and 90ies metal scene. One of their amps is for sale, of course located in Switzerland. Not mine and I have no connection to the seller, but thought maybe someone has interest in this one...

So I`m currently working on a DIY 2203 clone and trying to tweak it to my liking. Doing this, I am comparing it to my JCM800 2204 from 82. On thing that bothers me is, that I can`t get the lowend to respond the way I would like. There seemed to be a layer of low harmonics giving the lowend a...

First, Merry Christmas to everyone! My question is, would it be safe to use 1 Watt 10k dropping resistors in the B+ supply for the preamp in a 2203 clone? I know a lot of people prefer to use 2 Watt resistors at this spot. But than again, Marshall used 1 Watt resistors here. I`m asking because...

Hi, does anyone know, which is the usual OT tap used in 2203 circuits with a 100k resistor, 4 ohm or 8 ohm? And were there any changes in the 2203 line, let’s say late 70ies Jmp vs early 80ies Jcm800? Thanks

...or kind of not how I expected. I have this 2x12 combo with G12-65 speakers I wanted to put in a 4x12. After removing the screws, both speakers did not move. So I carefully put a thin metal ruler between the wood and speaker to get a tiny gap. After that I did put a screwdriver in the gap and...

Hi guys, I am currently building a TAD MV kit and came up with some questions for the the arrangement of the cables/traces inside the chassis. Rule of thumb is, that everything carrying VAC like heater supply or voltage before rectification should be twisted together and out of the way. What...

Hi, someone posted here that an easy check to see if all speakers of your cab are in phase would be using a 9V DC battery. So how does this work exactly? I was thinking of using an instrument cable, connect it to the terminal and press the other side of the cable (tip and sleve) to the two...

So what is a reasonable price for a Marshall 2204 from the `82 in todays market? Assuming it is unmodded and in very good condition? Thanks

Hi, I have a Marshall JCM800 2204 that runs on a low plate voltage of 360V. The voltage selector is set at 240V, my wall voltage is approx. 230V (EU). Is there anything else to consider when setting the voltage selector at 220V to get a higher plate voltage other than rebiasing the output tubes...

Does anyone know, what brand and material/type the red box (lego) caps were, that Marshall used in their JCM800 line in the 80ies? Thanks

Hi guys, I am able to buy a Marshall 4102 combo for a good price. It`s the 2204 circuit from 1982. Only question I have, if it looks ok and I should jump for it? Seller says that the pots were changed. Apart from that, it is in original condition. Maybe some of you experts can have a look on the...

Do they exist? We all know the rule of thumb, 250k for single coils and 500k for HBs. Then there’s Gibson that has 300k pots. But do any in-between values exist aiming at 400k or 450k, apart from the ‚natural‘ variance pots have?

Just saying. Located in Germany. https://www.kleinanzeigen.de/s-anzeige/marshall-jcm-800-2203-larry-grohmann-larry-amplification/2495581496-74-7659

Hi, one of my speakers in my Mesa 2x12 Rectifier cab makes scratching noises when notes decay. So I assume a recone is needed? So what would you guys do? If it would be a common V30, I simply would buy a used one and be done with it, but it`s a Mesa V30 (from `96). How much does a recone cost...
