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 have a little problem. I play a rocktron voodoo valve preamp with a marshal EL34 100/100 power amp. 
The sound is really amazing.  He is very rich but not artificial like other rack elements. 
It sounsds like a more precise amp head. 
 
The only thing I don't like so much is one frequency in the highs.  Whatever I do this frequency is already there.  Not that she sounds harsh... But a little bit brittle sounding highs. 
 
I think it's perhaps the typicaly British EL34 touch ?
 
Anyway.... I play metal (lamb of god,  god forbid,  pantera,  alice in chains stuff .....
I know everybody's here will say "change the tube for 6L6" ūüėā
 
But I'm not a big fan of 6L6 ...too dirty Mids and not bluesy enough (I love playing blues and for that the EL34 are awesome. )
 
After many researches I read that KT77 tubes could be a good alternative for me...EL34 sound with the lows of 6L6 , more nuanced Mids and beautifull highs... Not brittle like EL34's. 
 
 
So here is my question. What do you think about that.  Is here anyone that tried and compare these 3 power tubes? 
What do u have to expect? 
 
 
 
'Scuse my English.... I'm french and I do my best ^^
 
 
 
Thanks to everyone here.

I  have a Code 50, so I turn to a particular preset and it includes say, flanger. how do I turn off the flanger and maybe add chorus instead. I know that the MOD section can be turned off. If it is on are the inactive effects simply zeroed out or is there a way to enable and disable each different effect. thanks. It looks like this applies to PRE EX, DEL and REV as well.

A second question is can I use the headphone out into either the guitar input or effect return of a second amp, either tube or SS?

thanks

I've had a DSL40c for a year or two, and it worked fine until a few months ago.  While playing, the sound cut out and there was a slight burning smell.  I replaced all tubes and pre amps and it worked fine in testing, but then did the same thing when I got it home.  Repair guy thought it was a pre amp issue so changed those out again.  It worked fine in testing, and then did the same thing again when we got it home.  This time when we turned it back on, it would work, but sound would go up and down sporatically with some popping and crackling.  Replaced the tubes again, and it worked fine for an hour.  Then the sound cut out, and we noticed it would not switch channels.  After turning it off and letting it cool down, we turned it on again and it worked fine and channels would change.  I'm not sure what to do at this point.  My weekend routine of dropping the amp off and then getting it back (with high-hopes) has gotten old.  The problems have occurred while plugged straight into the guitar, as well as through a pedal board.  Also, the problems have occurred via multiple power sources in different locations (i.e. not always through the same wall socket).  

Thanks for your help

My DSL40C suddenly began a fading out static when the standby switch is enabled, or disabled. Also the volume knobs don't do anything, anymore. The gain knobs increase the volume, but there is really no gain. These problems began suddenly and together.  I have new tubes on order. What is the most likely issue?

 

Thanks!

My TSL 122 Combo  keeps red plating the tubes.  Everyone says these amps have the same kind of issues, but Marshall won't do anything about them, except to but a new board (thanks for sticking behind your products!). Anyone have any other suggestions? Thanks much!

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?

My JCM2000 TSL100 will power up and play fully....after a while 30 mins or so....it will fade out to no sound....or weak sound....power it down then up again ...it will play full for another period....had the smae problem before and took to amp guy...it worked perfectly for him...maybe he didn't play it long enough...so I said for him to replace all tubes anyway... it is now doing it again after maybe 50 hours of play....any thoughts or just preplace tubes again....if its a tube is it likely to work for a period of time after its powered down then back up?

One of my power valves is redplating, and prior to that there was a really loud sound coming through the sneaker that sounded like an electrical surge. Is it just a new valve required or something else. At first there was a noticable hum,  then I went to plug in my guitar and as soon as I picked up the cable, it made that loud bzzzzzt sound and I shut it off. I then tried it again and noticed the redplating.

Amp on clean channel super loud, when on distorted channel need to crank to half or more to equal clean on 1/4 setting, low gain 2 or 3, tubes or owner issue? Is this normal, kick in overdrive distortion goes through roof, in a good way. Loudness not like clean channel. Thoughts or suggestions, thanks in advance.

Hello...I have a JCM 800 2203 that I purchased back in 1981 and I wanted to replace all the tubes in the head after all these years. My amp has many hundreds of hours on it between practice and hundreds of gigs back all through the 80's.  I assumed that I had the standard compliment of Four EL84's in the output stage of the head...Everything I've read stated as such, and all the You Tube Bias Procedures led me down the same path....SO I ordered a matched set of TAD 12AX7's (3),  and four EL34's. Well, much to my suprise, when I took the back metel cover off the head, I did not find four EL34's...What was installed for power tubes back in 1981 was 2- 6550's, and 2- 6L6's. Both larger than the EL84's. Can anyone tell me why they (Marshall corp.) would do this...is there any special reason? I DO NOT want to change ANYTHING about the tonal characteristics of this amp. I would sure like a little enlightenment on the what's and the why's. I am truly facinated at discovering this..Thaks to all...Randy
