Amazing how good this amp sounds even through just the lab mic. It’s important to note that the jvm range (and uk made marshalls in general) cost less than half in Europe than what they cost in the us. Also I think for what it is, the amp is at least built to be repairable. All the digital components are on a separate board, so they can be replaced without having to replace the whole main pcb. Also it‘s easy to get access to all the parts, like e.g the front panel without having to take apart the whole amp. Here in Europe, they usually go for about 500-1000€ used, which is a pretty good deal in my opinion.
Great job diagnosing the problem. Seems like an amp with too much going on and quickly headed for obsolescence. You and Brad are the rock stars of amp repair.
Just discovered your channel researching affordable grab and go tube amps so I don’t have to drag my 76 2204 around. Ended up rebuying an ac15c1. Really enjoying the content, and I appreciate the time you put into it. Your voice reminds me of Jon Benjamin's.
I love the JVM series! Six years ago I got my hands on JVM 410HJS and I have been in love ever since. Along with the Plexi Marshall 200 Major ( I had the PA version), it is the best sounding Marshall I have ever heard.
He seems to like them too, because he is still using them the last time I checked. I bet he has spares though. I found the schematics for both versions, but I am not going to pretend I understand enough to work out the differences and how they affect the overall tone. I am looking for info where somebody has already done that for us. Short cuts :D
@@geomusicmove I think the JVM is much better than the JCM. Back in the late 80s I had both a JCM 2203 and a 2204. Both were full stacks, and I played them in stereo. At first I was satisfied with the sound they produced. But later I bought a used Marshall 200 Major and my world was never the same. If I recall correctly there were three variations of the 200 Major, and the one I had was the PA version. Without a doubt, I think that was the best Marshall I ever used. I currently have the JVM410 HJS half stack which I play in stereo with a Fender Twin Reverb. I have a 2555X which is based off of the JCM 800. But, it is not up to par with the JVM. At least not to my ears. Everyone is different, so please don't take my opinion seriously.
@@Walks-With-Pride Not many people rate the JVMs or the Jubilees higher than the 800s, but like you say everyone's needs/tastes are different. The only 100 watter Marhsall I've onwed was a JCM900 combo 2x12 back in the 90s, I don't care most people hate on the 900s, to me it was a glorious amp, very versatile and never felt I needed ODs or boosters with it, so there you have it. I've never owned a 100w 800, but only one of the 20w Studio Classic ones.It wasn't for me, it had a harshness to it I couldn't get past so I sold it on. I'm seriously considering getting an 800 reissue but my fear is whether it might be as harsh as the Studio version.
@@geomusicmove I enjoyed reading your comment. I think you should go ahead and get the JCM 800. I don't recall there being any harshness in their sound at all. Like I said I had two and I had no problems with either of them. The JCMs sound a hundred times better than the Silver Jubilee. They look cool, but the tone they produce is rather mediocre, in my opinion. The JCM is a good choice. I don't think you will regret getting one. I wouldn't mind having one again.
I had a VS265 212 that has similar problems. This was the first amp I decided to try to fix myself. If you hit a power chord you see the cabinet "move". I pulled the chassis and with the help of a magnifier headset, I found several "cold" solder joints. I got those reflowed, and found the cab to have that crazy vibration. I made a 5/8 thick back board, and I also added an upright wooden support vertical in the center. The amp was sounding great at this point, but it had already ruined my trust in it so i sold it. I went from there hand wired and tube amps only. I did buy a Jet City 20 watter for practice and a few others, I guess it all depends on your amp budget.
Your diagnosis at the beginning was great. I thought when I 1st heard the "comb-filtering" I thought that you were running a phaser lol and I was wondering why because it's so unlike you. Though I love and have had/do own Marshalls, I actually have this model on my bucket list because of the wattage {similar to the DSL-40 which is a kick-ass workhorse combo my buddy has that I've tried but don't own, so being to compare their build through your expert tech eyes was a treat. Can't wait for the fix and play. Looks a bit more prone to shock/vibration due to layout/construction/ complexity.
I bought one brand new 2 years ago and didn't play it for a year, never played it at High volume. I went to turn it on after a year of not playing it and all I heard was crackling. I took it into my amp man and it was not the tubes, it was not a resistor, it was a silver Micah capacitor. He said it was rare for that to go out and he replaced it and it sounds like brand new again.
I used 2 jvm410h stacks. I didnt have any problems and other than h&k duotone they were the best amps I played from the time they came out till I stopped playing for money.
Would be keen to hear more of your thoughts on these Marshall 205C amps! Curious whether also whether any mods can be done to ‘improve’ the amp, fully understanding also that ‘improving’ can be somewhat subjective when it comes to tone. I have a 205C and actually love the tone. The duo of the ‘mismatched’ speakers that Marshall selected for this combo is really nice - nice full and warm tones.
I have a 410H which I bought around the time of the JVM release on to the market and it was great but as I've gotten older I find myself not enjoying it so much. Something as simple as using a power supply that is shared with too many other electrical devices can cause it to be so noisy and there's just too much messing around with the 4 channels then 3 gain stages on each. I just go to my 80s JCM800 now as it's simple.
I got my JVM410H in 2010 and still have it. The OD1 orange channel tone for me cannot be denied. And having a second master volume is nice for guitar solos…I use OD2 for that with the other master volume
It seems anything that do more than one channel and high gain seem to be really poorly designed and made these days, especially for the money. It seems your next video on amps you recommend should be reliable amps under the price of a house... sorry, I digress. I appreciate your videos because a lot of the amps I've had my eye on are intelligently and thoroughly explained as to why they are not good choices.
@@goodun2974 Think I'll stick to my DSL's. At least I'm not overly paying for it's "Vonderfull construction" compared to that model. I'm kinda bummed...but a better educated bum.😥😞
I just purchased a UK 2005 JCM2000 off the Internet that was supposed to be in mint condition, What would make DSL 100 sound flat, fuzzy, with barely any harmonics, lacking compression, there's still sound when I turn the volume right off unless I tap on the volume knob, I checked the bias with a cheap multimeter, power tubes look old but there seems to be some life in them, this is driving me crazy, if you were to take one guess, what should be my next move if you don't mind me asking? ( please help, i haven't stopped for days)
The first step is to replace all the old tubes with some that you are sure that are in good condition. I've been tempted to replace random parts wen all was needed is a tube swap, if isn't the case at least you will have spares.
Honestly, I'm surprised at how good that amp does sound. Its really a shame that these amps all seem to have the shittiest plastic pots and jacks. If ANYTHING the parts that the user is going to beat the hell out of should be of the highest quality.
@@TheCyberMantis well in Europe they cost less than half of what they cost in the us. Used you can get one for probably about 500-1000€. For that, they’re pretty good amps.
There's a 210c going for a song locally. They're too heavy and too ugly but for a good price would you give a recommendation to pick it up? For reference, I already have a Runt 20 so outside of the wattage it's hard to see this giving me anything I don't already have in a much less portable form. Thoughts?
I was going to buy this amp until I saw this video. Not to mention that this amp was serviced (service sticker) before this video is throwing up all kinds of red flags.
It seems like they keep cheaping out on components to make these complicated amps instead of making simple amps that have durable and long lasting quality components. Then again, good luck affording a used 2203/2204.
Bastille Day! LOL. That thing sounds like a giant gold-plated pile of #*@%. That sounds like Marshall is dangerously close to Mesa-Boogie on the over-featured, under-engineered and poorly manufactured crap-o-meter. Sad.
@@PsionicAudio, perhaps your lav mic was clipping, because the amp sounded pretty cruddy to me. It'll be interesting to hear you play it on clean settings.
Don't mean to criticize but you have not included a safety caveat for aspiring amp techs at the beginning of this video. Poking around in their can be fatal if one doesn't know what they're doing. 👍
What a cheap Chinese POS that amp appears to be inside. And maybe that's just indicative of the way things (and durable goods) are in 🤡world 2022. I believe I'd pass on a 'current' offering by most of the 'traditionally' quality brands in favor of knock-offs (Berringer) if I wanted 'new'.
Hard to beat the sound and value of a Boss Katana. No tubes to mess with. And they aren't even made in China, like a lot of other higher-priced stuff, so that is a bonus.
My favorite band - RUSH !

@Guerrini2954 paid €700 for mine over 6 years ago. Floor model had I slight tear/scuff on tolex back of the amp at the top.

Profit over quality. Happens too often in this industry.

Whats that DSP Board looks like a bunch of chips you don't need in an amp is it DSP reverb?
Yeah, just reverb.
Is that a Texas Instruments chip in there? Didn't expect to see a chip by them in a guitar amp.
TI TL072s are in countless guitar amps.
Even the JCM900 waa riddled with op amps (such as the TL072). The Fender Hot Rod, too. You just never know until you look at the schematic!

Not in this case.
