    Went ahead and pulled the chassis as per request for some pics.
    Serial number is S/A 10823
    Chassis inspected by JM on orange label.
    Paper label reads to the best of my knowledge:
    date 25/4/69
    Chris B. Parel
    Tag B. Kath
    Top+bottom Kath
    D.L. finish
    (VB)
    inside of circle: inspection 4
    There are a few other markings/intials I cant' make out. Take a look and see if you know what or who they are.
    Does anybody reconize any of the names or intials?
    I know the inspection label is Jim Marshall, the others I have not heard of.
    Enjoy and thanks for the help.
    It was my pleasure to pull the chassis since you asked!
    BTW this amp is 100% unmolested! Except the groove tubes circa 83-84.

    I understand "nice wigs".:D
    But I am not so sure regarding the "photoshop is your friend".
    Are you saying I should have used photoshop to increase the clarity of the pics? Or are you saying I photoshopped them already? (adding something?)
    I don't have photoshop. The pics were taken with a junk Fuji 2.3 Mp.
    Just curious.
    Thanks.

    I understand now.
    I will need some practice, but will try to accomadate the page width in the future.
    Does it compromise details? I am guessing so.
    I need to do some testing on the re-sizing.
    Thanks!

    Sweet.

    I have two small box 50s, a '68 and a '71 but neither are as minty fresh as that one. That's really pristine. It looks like it's almost never been played. I've never seen the labels on the inside look so clean.

    How's it sound?

    I have a friend with an exact twin to that amp and his is mint also. My friend's amp is also a very late plexi, with the more modern (seen more in the 70s) style impedance selector like yours. Most plexis have the earlier style unit with the big button type plug for changing the ohm selection. Cool amps, and probably the last plexis made before the change over to metal panels in mid '69.

    Hi Lee,
    The head sounds fabulous. So good that I am afraid to gig or just jam around the house. You know how alot of amps sound so great right before they go pooffff!!? It's always sounded that good. I had used this amp full time from77 to around 89. Including a couple of times a year until recently.
    Back in the old days 77-89 it mostly was in the band truck in Nashville and Ohio.
    I always did try to bring it inside during extended periods of non-use!
    I am just afraid to push it anymore. There has not been any changes to the amp at all.
    So I just power it up every now and then to charge the caps and play through it very gently.
    Weird thing, I put it on stanby for about 2 hours last night, then turned it on to just sit and idle for a couple hours. Guess what? I forgot about it being on. Got up this morning and there it sat, it had been on idling all night long!
    Plugged a cord and guitar in, sounded as usual, wonderful.
    The cab was a 94 Matchless 1-12 8 ohm.
    I have alot more confidence in the amp now, but what a crazy thing to do!

    Hey man,

    Killer amp! These thins really sound great and are incredibly underrated. Compare the tone to most modern amps and they usually come up way short. Nice tubes, are those 6ca7's? One word of advice. I wouldn't use it with the original filter caps on the power supply and bias supply. That's where the real risk is in running these things. I've found that when properly serviced with new filters, properly biased and fresh tubes installed these amps are extremely dependable and can be used all the time. If you are afraid of loss of market value, I wouldn't worry, I've never had any problems selling any of my properly serviced vintage Marshall gear at current market prices. Bias trimmer would be nice too so you get set your bias reliably.

    So what are you thinking... I am serious.
    A changed out choke?
    I deal in artifacts and antiques as well. Take a close look at the patina(aging) on all the original parts. They all match in regards to appearance.
    I also just took a close look at the leads on the Partridge. They all look original.
    I am am interested in your input reagarding the choke.
    Let me know, I am listening and would appreciate your opinion and others as well.
    I know amps( I do some amp repair and have collected since 77 when this Plexi amp got me going. Although ....I am not an "Amp Ninja"), I have never changed a thing since I bought it in 77. It was dead mint when I acquired it.
    Overall impressions visually indicate no changes.
    Let me know what you guys think.
    Thanks,

    "wreck

    Uh, these things were born to be played. It would be a very sad thing to have it just as a 'noodling' amp at home. Let the world hear it. (But get a flight case! Only you should carry it. And jealously guard this in between sets!)

    Bring a backup if you're worried (as you should always, as well as tubes).

    FWIW.

    I have been collecting pictures can't afford that many amps. I have at least a dozen folders each one is a different amp all from 69 and no two are the same. Look at those weird pots on the volume controls never seen those ever. Marshall was the very essence of boutique back then.

    I can't believe you've used this amp that much and it still looks like that. Wow.

    Anyway, I looked at the choke in my '68 and it does not look like yours. But I think the choke in my '71 does look like yours, but it's in the bedroom and my girlfriend is sleeping so I can't say for sure. Regardless, cool amp.

    I very much doubt that the choke has been changed and if you have had the amp for that many years i cant see it being messed with ,but i know a certian store in northern england were famous for adding plexi panels to 70s metal panel marshalls and the partridge choke was always the give away,as i said i have NEVER seen a plexi with a partridge choke,always metal panel,having said that if you have owned this amp since 1977 i guess yours must be an overlap/transition

    LOL!!!
    They aren't copper they are some type of cloth.
    However you will now always been known as creating the Marshall slang for the tube retainers on vintage Marshalls as "Jerry Curls".
    Congratulations. You will never be forgotten KTT!
    From now on they will be known as "Jerry Curls".
    I love you man:AOK
