1980s Marshall 2000 Lead 250 Watt Head

[scozz]

Anyone own, or have seen, or played one of these? I've never even heard about this amp until recently, and I never seen a pic of one either, I'm sure they're very rare. From what I can gather this model was released the same time as the Jcm800, 1981,...actually April of 1981. They released one for guitar and one for bass that year.

I would love to see and hear one, even a pic or video of one would be great.


Anyone have or know of one?

Here's what little info I found, I copied it from Dr Tube website, listed as Marshall Schematics,...

"The 2000 Series"
"The 2000 Lead and 2001 Bass heads are probably the loudest and most powerfull Marshall tube amps ever built. These amps were introduced in april 1981, around the same time as the JCM800 series. It isn't clear if these amps were actually part of the JCM800 series. The schematics suggest they are, but you won't find JCM800 printed on the amps.

Special high power version of the speaker cabinets were made for these beasts.

Did Angus Young ever have a 350w head custom made?

at one point, years ago, there was a classified on here, someone selling one. It had the most info/pictures I ever had seen, unfortunately, the images were probably photobucket & have since been messed up, or gone...

They really did the world a disservice when they did that, because all of the archival images being shred across many forums. Probably millions of archive photos gone in an instant...

I did see one years ago on ebay. It was in the UK and was quite expensive. I'm sure some collector snatched it up. I've never seen one since.

this guy posted this, saying it was his. He also noted that his was modified...

Thanks for the link DOD! First one I've ever seen or heard so thank you for that!

Man it's a monster, the chassis takes up the whole width of the cabinet! I'm assuming that cab is a full size cab, 29 & 1/2 inches wide.

Runs on compressed air?

Must be damn heavy. It has recessed handles on the ends.

Malcolm played around with one during the Flick Of The Switch era.
See it at the 50 second mark.

Ok, that sounds REALLY LOUD from here!

Interesting watching them rehearse, you can see that amp head all through the video,...7:36 to 7:40,...16:00 to 16:04 + more. You can’t miss that head!

@Dogs of Doom mannn.. that's some nice beefy Marshall tones right there!

I read in an interview with Steve Grindrod that AC/DC took some prototypes on tour.

HaHa...I played through a bass version many years ago at a local music store. ( I was a working bass player in my younger days )
I remember thinking it sounded great, but it was huge, loud as hell and large $$. I was happy with my bass rig at the time, so I passed.
Thats the only one of these I've ever seen in person, or seen offered for sale anywhere, to this day.
I had no idea there was a guitar version until I saw this thread LOL.

Yes, I am working on a Series 2000 right now. It belongs to a friend of mine. But I am having difficulty getting the MIX inputs and Channel Switching to work. I posted a couple threads on here but so far, no replies that might help me. I would love to get my hands on an April 1981 schematic - the original. If anyone has any leads on the original schematic (or service manual), please drop me a line.

What footswitch are you using with the amp, and does the channel interaction happen both with and without the footswitch connected?

What footswitch are you using with the amp, and does the channel interaction happen both with and without the footswitch connected?

 

[TomCarlos]

I am using a two button, simple On/Off (SPST) switch.

The channel interaction is one thing - and it might be resolved.

The problem with my amp is with the Mix Input Cliff Jack. If you look at the schematic, it is NOT clear if the TIP part of the jack is Normally Closed (as are 99.9% of the jacks) or if Marshall did something odd my using a jack where the Tip=No, Ring and Sleeve=NC. The jack was replaced so I have no idea if the correct jack was installed.

 

[TomCarlos]

Ok.... It turns out, you CANNOT use a simple two button SPST switch. When you do channel adding, you need something like what I am showing in the attached photo. I have tested this theory with jumper wires - it works.

I saw one of these, a Bass head about a year ago at an Amp Tech's shop. It was his.
