    1st timer. I have a Marshall Master Lead Combo with SN A19508. Came across it in my Dad's storage unit & would like to when it was made and how much power its rated for. Also, would like to obtain a manual/schematics. Finally, what, if anything, the amp is worth. Thanks in advance for anyone's time!

    I'm not sure.
    I had one a long time ago...my first amp. It's 30 watts, solid state. It's not worth too much.

    A, if it is BEFORE the 5 digit serial, is 1969/1970.

    Can someone confirm???

    No, you're referring to the old serial system, when the letters would actually be after the serial number.
    This doesn't apply to the solid state stuff.

    Marshalls didn't introduce master volume amps until 1975 with the 2203 and 1976 with the 2204, and the transistor master amps came in around '76 too.
    What's the model number of the amplifier? (Should be four figures)
    This will help put an approx date on it.

    And no, it's not worth very much at all.

    If it's a model 5010 and looks like this:

    It's a 30w solid state amp. I have one. It was my first amp ever, that I got in 1987. For a solid state amp, it sounds pretty good. Not worth a whole lot of bucks, but now and then I see them go on Ebay for a couple hundred bucks.

    Cheers!

    You need to be a lot more specific on this Master Lead Combo. A picture would help. Is it a 1x12 or a 2x12 speaker combo, what does the grill cloth look like - "basket weave", or checker board, or solid black.

    I have a first year JMP 2199 (UK made) in my collection - 2x12 Celestion G12L T1632 8 ohm speakers, 30W, checker board grill cloth (only used in 76 from what I can find out). They are loud and clean, if all the electrics are good and clean. When new, they were a nice clean studio amp, but you needed "pedals" (effects) for "noise". These were made from 76 - 80.

    And WRONG, depending on condition and age, they go from $250 to $600 for spit clean. One sold on this board last year for $300 in mediocre and well used condition.

    Last - I've yet to find any conclusive info on the correct SN dating. Marshall was all screwed up on SN's in the 70's anyway, but particularly the SS amps. But so were most of the Amp companies at that time ... must have been the drugs around then. :hippie:

    If anyone can point to a website with accurate info, would be appreciated.

    Oh, that model 5010 is a much later series - late 80's. Not as "clean" sounding as the early JMP 21xx models. These are of the "JCM" series (JCM800) - "5010 Master Lead Combo, 30W 1x12" This combo was introduced in 1982 and discontinued in 1991. It is a transistorized version of the JCM800 4010 combo. Early 5010's were fitted with the red 12" 4Ω McKenzie speaker. Later 5010's were fitted with a 4Ω Celestion G12M70 speaker.
