I am in a quandry. I have a 1987 50W (2 power tubes) reissue.  Every search I do for this comes up "1987x", and they all seem to have an F/X loop-- mine does not. The S/N is RI935245707. The front is labeled "MK II" and has 2 ch, 4 inputs and looks just like the classic Marshall we all have come to know & love..

1) Does the 'x" mean F/X loop?

2) I know that it is a re-issue and was manufactured in 1993. Is this a "plexi" reissue or a "metal face"? I am not sure if a "plexi" reissue would have an actual plexi faceplate, just the internals.

3) Since I cannot find any info on it, is this some kind of rare bird or not?

4) Can you tell me how many of this model were manufactured or do you have any idea of the value? It seems odd that I cannot find any similar w/o an F/X loop.

Any info would be greatly appreciated.

Hi,

I need to replace the power tubes in my 6100LM 100W Head.

I am looking at purchasing a matched quartet of Tung-Sol 5881 (Medium) from Musician's Friend

Just wanted to check to make sure that these are able to be used in my amp.

I have provided the link to the Musician's Friend Web Site for your review.

I about the above in 1985. I just want to confirm what tubes are necessary.

Also, if I could register, that'd be great!

Since purchase amp always had a hum unless I touched strings.  Last month the amp spiked when I turned Standby ON.  Since then lost power on Classic channel and selector switch on head would not change channel, but footpedal works.  I returned to Sweetwater for repair/replacement immediately.  I received back stating "Reverb PCBA pins were lifted halfway off Main, glued in place.  Bias the output tubes...".  At this time I purchased Gibson cables CAB12-BL thinking the hum from bad Sweetwater cables supplied.  Still have hum at 1/4 volume, min Gain setting and the Channel Select on head still does not work.  It used to, and hum acceptable at low volume.  Is this correct, can I get replacement?

Hi, I bought a Marshall DSL40C amp in July from Gearnuts (www.gearnuts.com).  The amp has been working great until yesterday - a crackling buzz began and then I heard a pop and saw a small flash of light.  It looks like the tubes are blown out.  How do I get these replaced under the warranty?

Thank you,

Sean

My JVM 410C doesnt have any volume coming from the channels.

 

One switch works green yelow, not red.  Works fine with switch two.  Switch three works green and yellow, not red.

switch four doesn't work at all. 

 

No sound out of these channels without footswitch.  Same results.  Now, making a poping noise when turned off.  I just got htis amp in June.  Played a few weeks and then boom, nothing.

 

I tried using the FX Loop in back.  That's when this whole thing started.  As I correctly plugged in as instructions say, it immediately didn't make sound in these channels.  Unplugged, guitar going straight in, same stuff.  No volume through these channels.

 

The tubes are red, all glowing.

 

I need help.  Thanks.

Just purchased this amp. I am a little suprised at how hot the metal faceplate on the control panel gets during use.  I know tubes generate heat and the DSL40 has the four pre-amp tubes just behing that faceplate. Still, just wondering if this is "normal". This is occurring even in low power mode, at relatively low volumes (set at 2 or below) and the Ultra Gain at about three quarters.

Hi, I've just bought a DSL5C combo that sounds fabulous.

Just to know when I will have to make tubes replacement, can you tell me:

  • - if the 12bh7 power tube needs a bias adjustment when replaced ?
  • - if the ECC83 preamp tubes need to be balanced ones or not ?

Thanks

HI just got  a new (3 days old) JVM 205C and played it a couple of times then when I went to turn it on again it will not make a sound!

It starts and all the tubes light up but when you turn off the standby nothing happens and no sound at all comes out, not a click as if the standby swith is doing nothing.

I did read the manual about the FX loop button muting the amp without effects plugged in but I have tried everything I can think of so far, guitars, leads other power sockets but no go!

Anybody have any ideas???

Thanks

Mark
