Question about Marshall 1936 2x12 cab

[Brow]

Hey guys.

I have a Marshall 1936 2x12 speaker cab with 2 75w celestions in it and I just have a quick query about it.

The cab has 2 inputs on the back:

1 is labelled Left 75w Stereo 4 or 16 ohms and the other is labelled Right 75w Stereo 4 or 16 ohms / Mono 150w 8 ohms.

Am I able to plug 2 separate amp heads into this cab each on a different input or is this likely to blow something up?

I just wondered if it's safe as I'm considering using both my Orange AD30 and Marshall JCM800 2210 amps live and it'd be handy if I could safely plug both into the same cab

Thanx for any help.

Craig

If it's a stereo cab, then yes - you can plug two amps in, one to each speaker.

Hey Jeff, thanx for your reply.

That's the thing, I'm not sure if it is a stereo cab.

The internal workings of amps and speakers is 1 area where I don't have much knowledge, so I'l looking to you guys for help

Basically you have two seperate 75 watt inputs, so you can plug two heads in. But the speakers will only take a 75 watt load, not 150.

That should imply that it is a stereo cab.. I have the same cab too, tho i have never used it in stereo as i don't have another head, But it's definitly a stereo cab :fingersx:

Thanx for the posts guys

I read up on it on the Marshall website and I can indeed plug 2 heads into my cab aslong as I don't exceed the 75w rating of each speaker

Re: Question about Marshall 1936 2x12 cab

On the 4-12's there's a switch between mono and stereo, but I think the 2-12 doesn't have the switch. I'm pretty sure the jacks have an extra tang, which divides the two speakers, as soon as the second jack is used.

Yes you're correct, the 2x12s don't have the switch, just 2 jack sockets.

I'm gonna give it a test run in a few days and see how I like it

The bit about "75w Stereo 4 or 16 ohms" is worrying me. Is it 4 or 16? You need to know which before you connect those amps!!

I would open the cab to make sure what the impedance on each speaker is before trying the stereo thing with your amps.

Re: Question about Marshall 1936 2x12 cab

I just phoned someone at Marshall and he told me that (if stock) it has 2 16ohm speakers in it, so if I'm running the cab in stereo to set the amps at 16 ohms and if running in Mono I need to run the amp at 8 ohms to get both speakers

Apologies for reviving this thread.

I have a 1936 212 with "JCM 900 Lead" on the badge but have noticed other 1936 cabs that do not say "JCM 900 Lead" on their badges. So, what age is my cab and is it made from birch plywood? I heard that up until '97 they were made out of MDF which isn't as good a material for a cab as plywood is.

Any advice welcome.

Re: Question about Marshall 1936 2x12 cab

It's from the 90s. I'm not sure on the cab's material. If you open it up it's easy to tell of course. You can just remove one side-handle and shine a light inside.

Oh so it's an older one then. Hoping it's ply with maybe an MDF back if not all ply... There's a lot of talk on the Net about whether they're great cabs or not. Mine has a V30/T75 combo so one T75 was swopped out for the V30 which I prefer more anyway

If I open it up what should I look for exactly regarding the construction?

Re: Question about Marshall 1936 2x12 cab

It's probably MDF but if you pull a handle, you should be able to look at the exposed wood in the handle cutout. If it looks like multiple pieces of thin wood stacked together, it's ply. Otherwise, it's either MDF or particle board. Not likely to be particle board but I guess it could be. Particle board will look like small granules of wood glued and pressed together (I think it's actually extruded). And it usually has a really smooth skin on the outside. MDF will look more like paper pulp or sawdust glued and pressed together. The front and back also, usually, looks similiar to the ends. At any rate, that will tell you about what the sides are made of. Removing the handle should be enough to take a look inside with a flashlight and figure out what the rest is made of just by looking. Pull the back if you want a better look. It's a bit tougher if it's been painted but the surface of both MDF and Particleboard is usually more uniform than Plywood. You wont see color differences or any wood grain because there isnt any wood grain. Do a google search for MDF, Plywood, particle board etc. Clink on the images link. Should pull up plenty of photos.

All that said, if you like the cabinet, don't worry so much about what it's made of. Just enjoy it.

It just has to sound good with that speaker mix. I love the way the t75 and k100 go with the v30.

Thanks for the comprehensive answer

I'll dig in and see but like you said, why bother since it does sound good and I've been without a good quality cab for a long time now... its supposed to be made in England but I do not recall seeing that emblazoned on the rear jack end... far as I'm aware, the JCM range is British made. As for weight, it's not super heavy but it isn't what I'd call light either. Pretty solid cab I must say. I don't fear stacking another cab on top if I had to.

It's just that the Internet has made me worry if its MDF then I'm supposed to hate it, sell it now and make sure I get the Orange 18mm birch ply I've always wanted but shy-ed away due to price... I'll get that Orange eventually. Marshall is Marshall, right?

And it does I just need to drive more wattage thru it to get the best tone which I seldom do at home - the heads (Orange #4 and Marshall 6100LM) thru this cab are crazy loud if let loose. The Marshall has actually been re-biased to 50w to get more power tube saturation at lower volumes.

If you like the sound, why care what the "internet" tells you?

Good point. Now I'm questioning myself - do I REALLY like the sound as much as I think I do...? Time to go jam again to confirm lol.

I suppose I should mention that in terms of cost it cost me about $275 with the V30 onboard alongside one stock T75.
