    Hello,

    Perhaps you could help me by identifying my bass cab? The logo, grill cloth and speakers have all been replaced by me, in the style amp of a 60’s pinstripe on a budget. Originally a 1 x 18 - the cab had been converted to 2 x 12. I’m confused by the model numbers but think it may be from 66 or 66? Any info would be appreciated.

    I’ve enclosed a pic of the serial no. 5612 on the back. It sounds fabulous with my old Marshall valve Master PA, but totally amazing with a Selmer T&B head!

    I hope you can help. I’m just curious. I’m a Selmer man and out of my depth here!

    kind regards,

    Matt

    That's a rare cab indeed. I've seen a few 1988 model cabs but with the later basket weave and the side metal handles, your PA amps looks like one of the first '66 ones with the meter window on the front, is it a 50 or 100w.

    Thank you - I have seen this, but have no idea if the 1966-1967 is the Year or model number? I’m a Selmer man out of my depth!

    Without the original speaker and pulling the levant off a corner (butt vs finger joint) I doubt you will narrow it down more than that. IIRC there is a pic of one in the Doyle book. You may be able to see from the worn corner.
    Regarding the amp, most of that model were steel chassis but there were some 65 100w (45/100) versions on aluminium chassis. The early 50w is exactly the same as the more desirable wooden sleeve heads save for the meter on the front. The knobs on that are rare (same as early Park heads). I confess I broke one of those amps (missing quite a fe parts) for spares several years ago:(

    I am very grateful for your expert help, and have included a few pictures here. It disturbs me when I can’t answer with confidence should people ask me what these items actually are, and I like old gear and just like to know! Plus I can compare and check originality and Source correct spare parts. I know the power input socket has been changed on the PA head. Yes - the power amp chassis seems to be made of steel as my magnetic crab shows. I have a couple of interior pics too.

    For the cab, it seems to have Butt joints. And was originally an 18” as evidenced by the repurposed speaker mount. So definitely a bass amp? What would be the correct period head to go with this please, should I want to return to original spec?

    Many thanks,

    Matt

    Looks like a 66 to me, from the butt joints and the serial number. The logo and grill cloth are not original which is a shame. There are good repros available out there and would improve it a lot.

    Thank you Bygone Tones, I understand the logo should have a gold top, like my PA head, I looked into getting correct rubberised cloth but it was about £300 so I may save that option for another day. I used a grill cloth from Stew Mac. Which is strong and in the spirit of the original. I could perhaps stretch to the right logo. Is there an official Marshall name/model number for this cab? It is really sturdy and produces a great sound, even from the 2 x 12” sixties speakers I have in there just now. These are only 20w each - but will do (I’m not SO loud and they sound fabulous as long as I am respectful with my 60’s semi basses) unless I find a serviceable Goodman’s unit. Bass speakers tend to be much higher rated these days, and the old 18” speakers can sag. Happy to know if there is an 18” anyone can recommend? Nice to know the cab is potentially older than I am. I gigged with it last month.

    The head interests me - first of those I have seen with valve rectifier (should be a GZ34 tho’).
    How do you feel about pulling the chassis? I would really like to know the transformer numbers and get a peek at the circuit board layout.

    I’d be delighted to help, please tell me more about the wrong valve - is that serious, it has been that way at least 25 years!

    I’ll take some pictures over the weekend, and leave it in bits in case I missed something important. When the monster mains cable was added it was noted (if I remember correctly) that There was a mod to the output stage so it could be over driven as a guitar amp? There seems to be an extra input 1/4” on the far right channel too? I’m happy to pop it apart and would welcome any info you can offer. I used this with a pair of Vox 4x10 columns as a PA head before pairing it with the Marshall bass cab, but my Selmer T&B has the sound I love. Plus 100w so I have to be careful! Matt

    OK - I couldn’t contain myself - it was ily four bolts and you have all been so quick and helpful to respond.

    Here are some images of the inside of the head.

    it is still apart, so let me know if there are any areas of special interest. I hope you find these can tell you what you would like to know, I’m keen to expand my knowledge too.

    many thanks.

    Just saw a Marshall 1996 JTM45 Bass head on a popular auction site, script logo, aluminium block ends black/green - oh dear! ££££

    I think perhaps I’ll be sticking with the Selmer head for now. It sounds great! Some of you Marshall enthusiasts must have deep pockets.


    However, one of the transformer numbers on this auction item is similar. 784 183.

    Model 1988, it's shown in the old catalogues in the Doyle book.

    "Containing one 18" Goodmans Audiom 91 loudspeaker. Designed to give a consistent distortion free output of 40 watts, although the peak power output rating of the speaker is 50 watts. Height 32", width 24", depth 14". Complete with 5' speaker lead and waterproof cover."

    They are cool cabs, probably more desirable now it is a 2x12. I would definitely put some eric collins grill cloth on it. I am not a fan of the repro logos though. I would wait for an original logo to come along, or just go without. Maybe the logo on your amp is the right one, but be very careful removing it if you do, they are super fragile.

    Has it still got the original leather handles on the side?

    Sadly no, the handles have been replaced.

    Thank you so much for the model number. The logo is just a cheap generic one for now. I was in touch with Eric Collins, if the cab is quite rare I guess it would be worthwhile to invest in the grill material, but it is also gigged, and the rubber material doesn’t look very robust?!

    Maybe if I get a Christmas bonus?

    Thank you so much. A model 1988 bass cab from 1966 is most likely. That’s great! that would get confusing if I played a Rickenbacker 1997 from 1967 through it . . .

    Or a 1999 from 1964 would sound better.

    Dig the gear Matt and glad to see another bass player here, hope you stick around.
    I wasn't sure but I thought they were all generally guitarists here IMG_3295.jpg .
