    Some kind folk expressed an interest in seeing the beast. Well, started taking pictures now (finally put the guitars down...). Kicking off with my knob - what did you expect, classy contributions? Come on...
    Behold - the crevasse of overzealously tightened all-plastic grub-screw knobs. And only 1 of the ten fitted still has its silver cap - may replace the bloody lot with Fender barrels, or some chicken-head knobs so I can at least see where they are pointed...

    Ah but your knobs are already pointy!

    Why did they stop making the pointy ones. I like them.

    neikeel speaks the truth here, and yet...
    Step one pace away from the amp and they are invisible - and yeah, I know, my ears should decide, not my eyes... but occasionally it is nice to glance over and reassure oneself that the volumes aren't both maxed out before hitting the strings...

    My guess is that notoriously money conscious (aka tight-fisted) Jim found a cheaper knob than the pointy ones...

    There are more in my "Media" thingy...

    Serial Number:-
    Red block on the back suggest 1978, the number itself (10868K) confirms 1978 with the 'K' suffix. This number is ALSO stamped in to the chassis just beside the Inspection label...

    Inspection Label:-
    Dated 25th April 1979

    Power Valves:-
    KT77 (aka EL34 aka 6CA7) - Marked KT77 / 7826 Z / MADE IN UK

    the blue over cream GEC label is (as usual) almost burnt off...
    ...but that's The M-O (Marconi-Osram) Valve Company, Brooke Green Works, Hammersmith, London

    Date code is for 26th Week of 1978 (June/July)

    Pre-amp Valves:-
    ECC83 marked I63 / B7L3, thus Mullard, Blackburn ('B' code...), 1977 December

    Speakers:-
    Marshall badged Celestion G10-50 type T3137 with the date code EM10 for 10th May 1979 - this is a mild puzzle, since everything else points to 1978... perhaps the amp was put together and into the cabinet, and the speakers were inserted later before shipping it out? That era Celestion coded seem pretty accurate...

    Apart from the exact date - everything appears to be totally original 1978/79 original - including the fantastic sounds she makes... I guess because she was gigged frequently during her first 20 years, and then regularly played for the next 20 or so until now.
    I am one happy bunny right now :applause:

    I lied - put some even older Mullard ECC83's in the five holes (lowest noise ones in the two 1st positions...) and got a serious drop in noise (hiss) as well as replacing a slightly microphonic unit.
    Then noticed a slight honking when very loud - one of those lovely GEC KT77 has an issue - not major (yet) but it is microphonic too, more so than its siblings. So... now the hunt begins (although I may just put in a set of JJ or Groove-tubes pro-tem...)

    And the output transformer...
    C2668 Dagnall Electronics 100W output TX, as ued in 100W Plexi, JMP and JCM800 type amplifiers
    No wonder she sounds so good - even with a failing KT77...

    People just do not look at amplifier's innards. I have always thought a Club&Country would be a great platform to modify if you want to modify a Marshall.

    Very true, @mickeydg5 - and even without modifying her, she cranks up beautifully, sure, not to modern high-gain standards, but like a dirty Fender Twin Reverb. She makes sounds that just keep you playing her. Had a Traynor YGL-3 for a while, and this old girl even beats that for clean in to break-up (which is where I like to be...)

    Nice photo gallery Nick, my first and favorite Marshall was a 1978/9 JMP 2104 212 combo, first era of MV, I wish I had never sold that amp, but life had its priority’s ! :(

    Just had a great day checking over the biasing - noted the KT77 in #3 was mildly red-plating, not a lot, but the precursor to some real issues. Since this was accompanied by sum serious hum increase, I thought I had better see what was what. Moved 'em around and smacked 'em about with a chopstick - 2 are overly microphonic and probably on the way out... it HAS been getting some loud playing of late though.

    Turned out the nobheads who did the "alleged" bias adjustment in '87 set it to the hottest it can go without changing resistors. Currently it is set to the minimum (as in coldest), and tomorrow I shall raise it to the sweet spot, then put her all back together.

    Upside is... biasing now holds no mystery for me, and I am happy to do it myself, and I have learned an awful lot about snake oil vendors only too happy to part fools from their money.

    Clips will be coming soon - once she's 100% good to go :dude:

    Mine was a 1987 JTM45 Lead, 45W head dating from '65 - it was only on a long-term loan and went back in time - I sspent a long time going round and round kissing amp frogs before a Fender Bassman fell in to my lap. When Fanny Mae and Freddie Mac screwed us small business folk over, she had to be sold to help get cash to stop us going under and it has taken me a long time since then to find the tone I wanted (though a Traynor and an H&K came close...) until I lucked out on this monster on fleaBay...
