Marshall 1935 cabinet (1970/1971?)

Hi again folks, it's been a while!

I received a nice Marshall 1935 4x12" cabinet a couple of days ago. The speakers inside date back to May 18 1970 (EC18 date code) and all the Pulsonic cones seem original as well. It has a basketweave front cloth, metal handles and unthreaded sockets for castors. The speakers are a great example of Celestion messing up the labels: the speaker frames bear the T1511 model number code (G12M 55Hz), but the magnet covers claim the speakers are 75Hz. The latter is incorrect for sure.

The cabinet came to me wired at 4 ohms and the original harness had already been long gone, so I purchased some wire and rewired it to 16 ohms, which suits my needs better. Actually the readout I get is around 11-12 on my multimeter whereas most other 16-ohm cabinets give 13-14 ohms, but I've understood that it's not totally uncommon for older speakers to show a lower impedance (ok, DC resistance, but still...) Any truth to this?

I hope you speaker experts can chime in and share your thoughts, especially regarding if the cabinet is a 1970 or a 1971 - not that it really matters that much, just curious as usual. The serial number confuses me a bit, I'm sure some of you know better. The Marstran cabinet database suggests that the cabinet is a '71 since there are several thousands lower serial numbers than mine (43163) that are already marked as '71. Still, the speakers are from the first half of 1970 - so what should I call this baby?

The 1935 is a bass cabinet, but it seems to work very nicely with guitar too. Actually, it sounds excellent and I'll record some clips later on. ..and if any of those rumours are true, some guitarists actually preferred bass cabinets over guitar cabinets back in the day.

Any idea where I could find castors for this cabinet - and what type are they anyway? Pop-in?

Here's a gallery I made:

Here's a pic of the cabinet with my '68 50-watt Plexi Lead. A couple of years' difference, yeah, but still a nice couple, or what do you think?



Any comments are welcome, as usual!

Hi Jucciz
The EC denotes May 1970 on the speakers.
I understand that some of those magnet covers were mislabeled back then and that the 1935 model are bass cabinets with 55Hz speakers.
Those make great guitar cabinets but can handle lower frequecies much better.

Below 12 ohms sounds right on the speakers.
Metal handles indicate early cabinets.

Thanks for confirming my assumptions and findings. Now does anyone have further info regarding speakers, exact year of manufacture etc... or just comments in general?

Re: Marshall 1935 cabinet (1970/1971?)

It is an early 1970 cab for sure. Although that serial is unusually high for 1970. It might be a replacement. The jack socket and wiring are definitely not original. So maybe the serial was grabbed from another cab? Hard to say, but Id expect to see that serial around mid-late 71.

All 55Hz pre-rola speakers have 75Hz on the label. Perfectly normal. Show me some that dont!

Just hope the speakers are still in good working order. Check the spiders over & check for coil rub etc.

The castors would have been push-in revvos. good luck finding any of those...

Thanks george for your wisdom once again!

Yeah, I bet the castors are next to impossible to find. I saw a quad in eBay and the asking price was ridiculous: $800. I wonder what would be the easiest way to get wheels under this big heavy box without having to drill new holes. Well, I could always order a roadcase with wheels on the base... something like this perhaps:


Also my guess was that the jack socket is not original. It still does the job just fine and does not bother me. The speakers seem to be in a good shape: I tested the cabinet with a 50-watt JMP running flat out and couldn't notice any unwanted noise. The sound was fat and punchy, very musical indeed.

Thanks for confirming that the cab itself is an early 1970 even though the serial number points towards mid-1971.

Any idea how much is this thing worth as-is? There's an equally old bottom cabinet in eBay: casters (original?), reconed speakers and overall condition somewhat similar to mine - the asking price is $2550. Is that quite optimistic or are these things really that expensive? Of course bottom cabinets are more scarce and thus may fetch a bit more.

yes that one is definitely optimistic. the castor frames look original, but the actual wheels inside them are not. too small. reconed vintage speakers are only worth a fraction of speakers with their original cones. you will see dealers asking those kind of prices but only idiots actually buy them.

i think most people buy the fender push-in castors.

Will those Fender castors fit the cabinet without modifications or what's the deal here? Can you point me to a specific product somewhere online?

pretty sure its these:

Amplifier Casters, FenderŪ replacements | Antique Electronic Supply LLC

Ive never tried them myself, you might need to file them down a bit to fit the marshall sockets.

perhaps wait for someone else to chime in that has actually used them.

Re: Marshall 1935 cabinet (1970/1971?)

I found this:
NEW Fender Swivel Amplifier Caster Set | eBay

With a little fine adjustment those might fit, right? Someone please chime in and confirm this, please.

And then on to another question: the Doyle book mentions "Brown Two-Tone Basket Weave" as well as "Grey Basket Weave", also known as Salt and Pepper. Now the grille cloth isn't particularly black&white (at least anymore) - more like yellow/brown'ish, but can someone (george?) confirm which one the grille cloth actually is? It would be easier to see if the two examples were sitting side by side for sure.

The brown one was used in '68-69 according to the Doyle book, but Marshall is notorious for transition periods, sometimes surprisingly long ones, so in that perspective an early '70 cabinet just might have brown basketweave, but... someone must know better than me.

And here's an interesting one: I found a cabinet from amparchives.com that has speakers with a date code EC19 - one day younger than the ones in my cabinet. The serial number of the cabinet (a 1960 angled) is 27880 and mine is 43163. This really supports the theory that the serial number plate (or perhaps the whole back plate, who knows?) is from a later cabinet. We'll never know.

Ive only seen brown two tone on custom color cabs. always salt and pepper on the standard tolex.

the only way to be sure is to look at the edges of the baffle where it hasnt faded. if you dont want to take the cab apart, you might find some black strands on the inside. or maybe you might be able to look under the white piping. its going to be S&P though for sure.
