old marshall head

Re: old marshall head

I remember putting Marshall logos on non Marshall stuff to make it look cool. :) Perhaps that's what happened here ? Marshalls with a black plastic panel are bass amps. But without piping and a fuse on the front ? Sorry bro, sounds to me like somebody made an amp look cool there.

Lately, it's been fashionable to butcher the logo to arshol or Warshaw on real Marshalls .. I passed up on buying a really beat up "snall" 2203, thinking I would get that sound and a clean channel in one amp that would sound too good to be true.

Peter,

The first Marshall amps were JTM45 and they were actually about 35 or so watts, there was in fact a handfull of amps called the JTM45/100 which was a 100 watt amp but those were ALL handwired and had KT66 power tubes, square logo's and were made in the late 60's...I have told you what I think your amp is and based on what you have told me about it I stand by that.

To be honest the blackface panel, front monuted fuse holder, etc make me thing that it might not even be a Marshall but if it is then I still put it as a mid 70's 1959 Super Lead.

Re: old marshall head

I had a late 70s solid state marshall with a black faceplate. It was a 100 watt combo, from 78.
 
Re: old marshall head

the guy who invented fire i dont know if its hand wired or not i didnt understand your question about the pcb board. the amp i have got is the exact same inside as the first jtm45 100watt amps.at the side of one of the power valves scratched on the chassis is kt66.i seen somewhere where that marshall used kt66 valves for a while then started el34 valves because they were cheaper.that was in the 60s for the jtm45

thanks peter

Does it look like this? This is a JTM45/100
 
Re: old marshall head

chopthe rocker some of the first jtm45 were 100watt check four posts up from the guy who invented fire. jumpmarine it is the exect same as that.but the back facia is brown and the front is black.at the front left side at the end where the two switches are there is a fuse.all the front knobs are really old fashoned not like yours

thanks peter
 
Re: old marshall head

jumpmarine i have just noticed the big middle transformer is turned with the bulky bits to the back and front and the end transformer on mine is covered with a metal box

Re: old marshall head

i said further up i had no camera and would get some photos in a week or two when my son comes here do i need photos now when it like the amp in jumpmarine photos.admiralb what do you mean by that statement

Re: old marshall head

Well, you describe something that might be quite rare (or might be a ripoff)...you know what an EL34 is, but you don't know whether it's PCB or hand-wired, even though you pulled the chassis.

And most of all, you're asking for advice on a guitar pickup forum. There are many amp forums with more knowledgeable folks, some that specialize in Marshall.
 
Re: old marshall head

Here is the deal man...you do not have a JTM45/100. IM not trying to be an ass but none of the old Marshalls had a black face plate, none of the old ones had a fuse holder on the front plate, none of them had the large logo you said yours had...you don't even know if it's handwired or if it's on a PCB, first it had EL34's now it's KT66...come on bro

Im not completely sure what you do have but like I keep saying if you get those pics I can tell you, or just get the serial number...it has one, it's on the chassis...
 
Re: old marshall head

I'm with TGWIF on this one. In fact, I'm not convinced it's even a Marshall to begin with.

Chops, 4 tubes doesn't necessarily mean 100 watts. There could be 4 EL84's and it won't be 100 watts. ;) I'm sure you meant EL34's but just makin' sure, bro. ;)
 
Re: old marshall head

the circuit boards inside my amp are boards full of small holes the components go throught and soldered i dont know what you call the boards.i didnt say it had el34s then it had kt66s i said it had el34s and i said it had kt66 scratched on the chassis in front of one of the valves.i told you it does not have a serial number. admiralb i think it says this is the amp section.the guy who invented fire have you seen any of these first marshalls

Re: old marshall head

You have a 1974 or later 100 watt head, if in fact it is a Marshall. It's got a PCB in it, not PTP (point to point) wiring. Now, the serial number is usually stamped on the back of chasis and begins or ends with a letter. If there isn't one, it's not a Marshall.

Pics are necessary.
 
Re: old marshall head

...assuming Peter is on the level- it appears that Peter isn't familiar with the term PCB- Printed Circuit Board. He clearly described a tag board- which would make sense in an older Marshall. As a lot of people know, the plexi faceplates crack and are often replaced, as do the badges on heads and cabinets. Although I've never seen a black replacement plexi faceplate- I've seen some doofy lookin' ones (then again, it could be a Park plate...). The logo- again, if you broke the logo off your head and you really wanted people to know you had a Marshall, and the only ones available were the big ones...

But I don't know what to say about the fuse on the front...
