Howzit?
I am thinking of letting this amp go since I haven't been playing it and I need cash to help fund my Hollowbody search.
I am just struggling to figure out what a reasonable asking price would be. I'm also wondering whether the cab is worth more or less since it's the bottom one?
So by the serial you can see that it's a 1969 or 1970 model. It comes with the old cover and the old round kettle plug.
Any help would be appreciated.

I'll trade you an Epi dot for it ?

It looks to be a very nice setup....however
1. are the speakers still the original Celestions (not reconed) ?
2. are the transformers still original ?
3. any electronic mods ?
4. is the amp in good working condition ?
5. do you have an exact year date for the amp and cab ? (do these belong together)
6. does the amp have any provenance ?
One thing that may count against it is its bulkiness,weight and power. The modern player prefers compact gear that's easy to transport or lower wattage amps so that the sweet spot can be reached sooner....

1. Dunno, I remember that I took the back off when I bought it to take a look and one of the drivers was a replacement
2. Apparently it's all original according to the guy who serviced it when I had the valves replaced
3. Apparently no
4. Yes, played and gigged with it for a few years, everything works 100% and I don't actually want to let it go but money you know.
5. Not for the cab, I bought the cab with a different amp years back, There should be a way of estimating the year of the cab because it's the old grille, small logo and the input jack is at the bottom, the cab is also missing the wheels.
6. Yes, it was once owned by me, I'll sign it and take a photo with myself and the cab. So no. I bought it off some guy in the Junkmail years ago.
Would it help if I take some pics of the inside of the cab? should I maybe take photos of the guts of the amp as well?

Having bought two similair amps last year ('69 JMP100 SuperPA and a '73 JMP50 Bass) and knowing what its like to try offload gear in the current economy I'd guestimate you'd get R5k for the head ☹
As Vic said there is a big push towards lower wattage amps and 50/100w heads just aren't as attractive as they once were, that said I practice with my 50w ?

Actually that serial number puts this amp as manufactured in 1975, not 1969 or 1970. Post a pic of the internals.

With my *limited* knowledge on Marshall history, i know '75 was the year the company introduced the master volume to the Superleads, which this doesn't have.
Which either means:
1) it's pre-75
or 2) Superbass's didn't have master volumes. I'm too lazy to research right now ?

No dude. The serial number is SB/A 3389G if my eyes aren't failing me. The SB/A part means its a 100w Superbass and the G at the end of the number is the date code. If it was a '69 or '70 there would either be no date code at all (Marshall introduced this date code in July 1969) or the date code would be the letter A.

I can vouch for ShaunF really knowing his stuff about dating Marhsalls.. Check his other threads, very interesting stuff.

Is the front panel metal or plastic?

You're partially correct. 1975 is when the Master Volume amps were introduced, but where you go wrong is that you seem to imply that the Master volume was an addition/change to the existing models. Actually the Master Volume amps were introduced as a completely new model, the 2203, and both the Non Master Volume 1959 Superlead models, Non Master Volume 1992 Superbass models as well as the new Master Volume 2203's were sold up until 1981, when the NMV models were discontinued and the 2203 made way for the JCM800's. The exception to this is the NMV Tremolo Superbass models, which were discontinued in 1972.
Interestingly between 1975 and 1981, the new master volume 2203's outsold the combined total of non master volume amps by a ratio of 15 to 1.

By the way, I'm no expert when it comes to Marshalls, or anything else really. I just happen to have a copy of a really cool book called The History of Marshall, by Michael Doyle, who is the real expert. I am just regurgitating what is in his book, which contains a huge amount of info about the amps themselves, Marshall cabinets as well as tons of info about Celestion speakers in general.
If you can find a copy of the book, all the info I have posted around the dating this particular amp is on page 144 and 145.
Another interesting bit of info, in July 1969 the plexiglass panels were replaced with the brushed metal panels, and at the same time, the Date Code was added to the serial number. The first date code, A, was used on amps produced between July 1969 and December 1970, and therefore covers a period of 18 months which is the reason why there are no B date codes.

Don't we all get our knowledge from books or journals, etc ? Well at least now we know who to turn to when wanting to know anything about vintage Marshalls ! ? Thanks Shaun.
shaunf
Thanks for the photos.
Can you take the whole chassis out the head box, turn it over and take a photo of the internals? ie: the circuit board? Also, when it's out, have a look on the 2 big transformers, there should be some type of model code on them too.
Also, if you look on the steel frames of the speakers, there will be a model code starting with a T on each of them, as well as a date code, probably consisting of a 3 digit number/letter combination.
The above info will help with guestimating the amp and cab's worth.

The metal panel would confim the +1970, that an the inspection date. '75 should be PCB and not point to point wired too.

Ok, here are the codes for the drivers:
They all have T1221 on them and then these:
FG 26
GG 5
FG 19
FG26
I couldn't see any numbers on the transformers, they do look old though, the wires coming out of them look old and brown and they are bolted to the chassis in the same way as all the other stuff.
shaunf
The 2 FG26 Speakers date to 26 June 1974, FG19 to the 19 June 1974, GG5 to 5 July 1974. From that, I'd say it's highly likely that all 4 speakers are original to the cabinet.
Value wise, it's really down finding middle ground between what you want for the kit and what a potential buyer is prepared to pay.
Make no mistake, these are great amps, however as others have mentioned, they're not particularly practical, as they are big and heavy, as well as very loud. These later circuit board JMP's aren't particularly in demand, as they aren't as easily tweakable as the earlier turret board ones.
The cabinet is nice, provided the speakers are all working properly, with no buzzing, voice coil issues, reconing, cone repairs etc.
If this was my kit that I was wanting to sell, I'd probably price the head between R6-7k, and the cab around R4k and be prepared to negotiate. It's probably not going to be an easy sell.
