I have a DSL 100h that has been fading in and out and crackling for quite some time. It seems to only happen on the clean channel and makes no difference, if I have my pedal board plugged in or not. I have the fx loop turned off, so I believe that that part of the circuit is out of the equation. I just swapped out the tubes because I suspected the pre amp tubes were bad from some other things I read and still no luck. Has anyone else experienced this?

Hello everyone i hope your all doing well

I recently we are talking the last 4 days purchesed my dream amp a marshall DSL100HR. I was very excited to finally be able to get my hands on a marshall super lead series amp. The dream has become a bit of a nightmare as currently i am the proud owner of a fancy paper weight. I handled the amp head with extreme care when i got it. I let it acclimate to my house temp befor even taking it out of the shipping packiging then when i did i was baby gental in doing so i set it up correctly and double checked so befor even powering up the amp. When i did power on the amp i let the tubes warm up like i read to do so i did this for 15m when i switched the amp to power low mode on i think that its 50watt in that mode. I heard a loud pop pop pop buzz and everything died the amp became unresponsive and the only thing that seemed to be working was that the tubes were lighting up properly and i could run the amp in standby thats it. the front panel was dead the foot switch was dead but the amp could still power on does anybody know what the hell happand ?

what did i do wrong did i just get a lemon ?

is this common with this amp range ? 

I am not rich it took a lot of financial planning to be able to afford this amp i am so bummed out. I did speak to the place i bought it from and there sending me a return label and when they get it they will ship a new DSL to me but this whole situation sucks. Thanks for any insite and help i wish everyone well !

(update) I got the return label sent the amp head back there processing a new DSL100HR order for me i wont get it till tuesday/wensday hope the one they send me works ! If the new DSL100HR also has issues i will most likely swear off tube amps forever not at all pleased with my initial experience at all.

(update 2) I have the new DSL100HR and this one works so i guess i got a lemon befor all is well now enjoy your lives people stay metal ! stay rock and roll ! most important stay safe out there !

Amp is a little over a year old was fine then past few weeks after warmup the volume would dump. All cables, inputs were checked and new JJ tubes put in which seemed like it fixed the issue However when I engaged the Tone Shift button the volume dumped again and when manipulating this button it caused the amp to crackle and seemed to be shorting out the power which intern was dumping the volume.. My tech replaced the Tone Shift curcuit but still when pushing the button in it causes the same issue, we are at a lost..and frustrated...Any Comments or Suggestions greatly appreciated

Hi there.  I am not a native but I hope you'll be able to get me right.I have been using Dsl 15c for about 2 years and all of a sudden the amp stoped producing any sound. All controls freeze, footswitch is non responsive. Led’s and tubes are still lit. No pedals in line. I turn power switch off then on and hear sound like a relay click in the background and then sound immediately cuts out.  My tech told me the problem is 99% in the microcontroller AT2313 because inside all fuses are still intact.  He was able to read the code and fix errors that cut the sound out. However, it did not help because some of microcontroller ports were damaged(most likely it was a factory defect). Is it possible to re-record the code to new microcontroller or maybe there are some other options to consider?

Thanx.

Hello!  I have a Marshall DSL40c, which I absolutely love.  I swapped the speaker out for a Celestion Vintage 30 (16 ohm) a little over a year ago, and it sounds great.  However, I recently got a lower wattage tube amp (Vox AC4TV) and have been running it through the DSL40c (basically using the DSL as a speaker cab, with the power chord disconnected). 

So here's the problem:  After 2 days of using this configuration, the DSL has started making a sound when I play the vox through its speaker.  The best way I can describe the sound is that it is like a tabmourine, like those little metal disks jingling together.  It does this on certain notes, like the open low E string, or a C chord, but not on other notes like a B chord (i.e. 1 fret away).

When I run the the Vox alone through its internal speaker - no issues at all.  When I run the DSL amp section alone through it's vintage 30, no tambourine sounds, although it seems that the green clean channel is lower volume than it used to be (the other 3 channels seem to me the same volume as normal).  There is also some instability in the volume (goes in and out, but in a sublte way).  There is some clicking and popping when I first fire it up, but this stops after it has been on for a while so not sure if this is normal or not.

I have been looking up reasons why amps may rattle, but everything I am finding describes issues with the tubes that are being played through - my issue seems to be a bit different, since the rattling (tambourine jingle) sound I am hearing seems to be coming from the Marshall when I am not using its tubes (playing through the Vox as a head).

Is it possible that a tube has gone bad in the Marshall, and when I play the Vox through the Marshall's speaker, the vibration is rattling the broken tube and making this tambourine sound?  Would a reduction in the volume of the green clean channel imply it is a preamp tube vs power amp tube (since the other channels are unaffected?)

Thanks for any help you can offer.  I don't mind taking it in to a tech, but I have read a lot of posts of people who took their amps to techs and had tubes changed, etc. and the problem persisted.  I want to have a pretty good idea of the problem before I start investing in having it fixed.

Thanks!

Hey all, 

Who has been working on the schematic for the new DSL 1w (2018)?

 

I've got mine open and have started thinking about some tone mods but would love any help with the schematic, part schematic or even a mod list.

I'd be totally happy to hack mine up first if anyone has a mod idea too.

I can read a schematic but I'd completly f%^$ it up if I tried to wrtie it out just via the PCB so if you'd like to help let me know and I'll send the high res pics ( assuming you dont have a 1w yourself).

Also I'd be all ears for some tube advice. I've put a 5751 inplace of one of the 12AX7 and its a bit better to my ears. I'm going to say V2 is the dirt channels V yeah?

So far I love it and i'll be interested to see what Blackstar do next with their future 1w.

 

S.

HI all, 

There is a DSL15 head with MX412 for sale at a good price about an hour away from where I live and I wanted to ask a couple questions before I decide if I wanna go check it out or not. 

Is a 4x12 too much cab for the DSL15? I mean, will it have the same punch? I don't play in a big space so that's why I love the 15/7 switchable watts on the head. Would I be better off with a 2x12 or even a 1x12? I have a Blackheart Handsome Devil combo that has 15/7 watt option and it's great but I want a half stack configuration and, well I just really want a Marshall! 

My second question is about the tubes. I notice the head uses 6V6 power tubes unlike the big guys with EL34s. Is there a big difference? I have a Fender that uses 6V6s and it's great, but I want that Marshall roar. Can the DSL15 get me to close to a good Led Zep classic rock type sound or should I go for something else?

 

Cheers!

My DSL started to misbehave after about six months since I bought it. When I turn it on, the tubes don't light up so the amp itself does not produce a single sound. Now, I have tried to send it back to the store where I bought the amp but the damn thing magically started to work there in fornt of the repairer so he said that he could not find what's wrong with it. The problem occured a few more times so I contacted one of the local electricians and he did the job and the amp finally worked. After approximately two months the same problem occured so I asked the same guy who fixed it earlier to fix it again, and again it worked. Now after a month or so, it has happened again. Has anyone experienced a similar problem? I need some advice. Thank you :)

Hello, 

   I just joined the forum so please excuse any incorrect behavior. I have a new dsl 40c with maybe 4 hours under its belt and all of a sudden with no warning it quit working. No sound whatsoever. The power light comes on and the tubes all appear to be glowing. It's still under warranty but I'm really questioning this purchase. After going online and visiting a few groups it seems like this is a fairly common issue. I guess what I'm looking for is a few people to comfort me in my time of need! Comments ate certainly welcome. Thanks so much!

I have looked for a definite answer to this and have not found one. I played my amp the other night with no problems, but last night as I turned on the amp it just died on me as soon as I turned the standby off. There was no noise, pops, crackles, fizzes. It just turned off. I checked the main fuse and it was blown. I have not had any issues with tubes and they have not shown any signs of wearing out. I made sure my amp was connected to the cab correctly (remember i have had this rig for 8 years) and that I had a speaker cable rather than a guitar cable.  I found online there could be issues with impedence and what not. I took the back off of my cab and noticed that a positive lead on one of my v30's became disconnected.  I thought, 'Could it be?" So I reconnected it and replaced the fuse and the amp worked as advertised. I played for an hour or so and no problems yet. Could it be that the discoonnected positive lead on one speaker caused it to blow a main fuse?
