When I was younger there was a tube tester in almost every store. With the price of tubes these days maybe we should go back to doing that. I guess you can buy tube testers easy enough nowadays. Cheap tubes were fun if you were a tube Junkie. I am a recovering tube Junkie.

I enjoyed playing my 1987 50 watt, Silver Jubilee, one 12 combo on stage back in the day. It covered many music genres and is fairly compact. Still have it.

Thanks for sharing your knowledge and expertise on this one Lyle.

That’s a nice sounding amp! Never really considered that model.

LOLOL when your meter did its auto shut off beep i thought "god damnit did i leave my meter out and on" then you said "thank you meter" and i realized it was on the video.

Ayyyyy Lyle finally gets in the same head I have! I've had mine for 9 years, one full tube change and re-bias, zero issues in that dept since then. Can't remember the exact year I re-tube/biased it or how hot/cold. Probably shoulda wrote that down.

Considering that the DSL100H is only about 1/3 the price of a JCM800, and is arguably more versatile, it's hard to beat in my book.

Cool beans😎👍

I was just at GC looking at a used DSL 20C. Still thinking about it

Great video Lyle, I have the same style amp except it’s a UK JCM2000 DSL 100 it’s been a good amp so far. But it will need a recap soon

My favourite DSL is the 1 watt 50th anniversary model (the 2000).

Curious how you feel about the Synergy amp heads from Boutique Amp Distribution. Supposedly Dave Friedman, Mike Soldano, Bruce Egnator, and Steven Fryette all collaborated on its design. I know it’s a very different beast with interchangeable preamp modules that all have some differences between them, but I’m mostly curious about how the power amp section and transformers are built in the head, as that is the consistent part.

2nd video with playing please!

Have you had to work on the mid 2000's DSLs? The 2005 DSLs remedied the bias drift of the earlier ones. The new DSLs are decent (the 100h and the 40c) and they are what they are, pcb based stuff but like you see, very easy to work on. A hell of a lot easier to rip that thing apart than some of the other alternatives.

The Marshall branded tubes they used in the DSL and TSL amps are prone to noise and failure. They look kinda like JJs inside but there is no oxide coating on the plates. It's rare for me to find one in V1 that isn't noisy.

Crazy how much extra room there seems to be in there. Why not a more spacious pcb? Forgive me if I haven’t looked back far enough (I’ve been watching from this channel for a couple months but did try a search of this channel) but it would be great to see the cleaning routine for switches and pots as you talked about here but we didn’t see. I bought an 80s Marshall and it came with unbelievably crackly pots. I tried my best to get cleaner in there (from front and back) with only a little success. Checked it in for a repair and my tech says he was able to clean it! No cost other than the bench fee (I’ll call that a bargain!) but it’d be great to see some tips for attacking frighteningly noisy pots and switches.

Gotta say, not a bad sounding amp. Always wrote these off as a meh, amp. If it's on a backline no complaints.

Honestly, these look better built than the JCM2000s. Pots still look cheap as hell, but at least the power tubes aren't going to have a board go conductive.

How cool would it be if Marshall made their amps to the standard of Fryette or Friedman? Love the Marshall sound, but the build quality will keep me buying other brands.

i forgot to indicate mine is the older one version made in engald in 1990

Pots and jacks look cheap. I also don't like pcb-mounted tube sockets, but lots of amps have that. At least the power tubes are chassis-mounted. These amps don't cost that much compared to other tube amps, so I guess it's an okay deal. I think I seen these over at Sweetwater the other day for around $1,200. A 100w EVH is twice that price.

what size pots are in the DSL

hello thank you for the video, i' ve bought one of them, i repaired it 'cause was fault and now is working, however i noted someone modified the bias circuit and now this is fixed and no more adjustable. I don't like so much this mod, do you know something about this mod? furthemore the head is very crispy , too much on my opinion, is it possible the bias mod is the cause? it is equipped with 4 GT Gooves tubes on final and sovtek ecc83 in the preamp. Thank you so much for your attention Carlo

Hey Lyle what's your opinion on those pots? are they similar to the ones in a BJ ?

What are your thoughts on the newer DSL 100HR?

supposedly the iron in the marshalls made in Asia (like this one) are the same as the UK built ones (all Asian made iron). can you confirm this?

How did you clean the pots? Did you use something like DeoxIT F5?

what a coincidence.. Just opened a DSL50(that someone dropped)

Your wife must have nerves of steel. 😀

Aah lose solder joints, oh well meat loaf for supper.

You didn't test or monitor the bias stability, bad idea. This would be tested over a 2 hour period at least...you didn't replace the bias pots which fail frequently and cause the output tubes to burn up. The bias pots should be changed every time the amp has a bench service...because they fail all the time. You didn't check the speaker jack which might have burned jack switch contacts, a very common problem in these amps. Also all the transformer voltages should have been tested....finally you should have tested the board for insulation failure at the output sockets ( a standard test which is well documented) . You did about 1/2 of what should have been done. You have a lot to learn about DSL amps.
