    There are covers for the ST70 in brown and black.
    I have been offered one for my amplifier in brown.
    I do not know if it's according to my model. What times or what models used one model or another?

    From memory ( and I think there is a wiki even on this )   it goes  brown   grey   black from past to present day..
    Personally   regardless of  keeping things proper with respect to model/year     grey is my favorite..

    Pillo69 --- the original ST-70 (circa, mid-1960's) used a Brown cover. Even those from the early 1970's used a Brown cover.

    The only Black covers that I have seen were those repainted by some previous owner.
    I don't remember a Black cover on a new ST-70 in kit form??!!

    Covers of ST70. Empty Dynaco Covers

    Hi Guys...
    Early covers for the ST-70 were Brown (I have never seen a Grey cover)....Shortly after Dynaco's move from Philadelphia, PA to Blackwood, NJ they changed to a Black cover for the ST-70, MK III and PAS 3X. Dynaco's last full color brochure shows all three units on page (20) with the new black covers and Modern block style Dynaco label.

    Just to add what Kevin has mentioned. Years ago I heard from an old Dynaco tube guy that one of the reasons they made the switch to the BLACK covers was that sometimes on the top surface of the tube cage the brown paint would actually turn a black color from the heat of the tubes. This would not happen to all tube cages but in some cases if the amp was left on for many hours, the heat from the four output tubes and sometimes the rectifier would turn the brown paint a blackish color. He said that Dynaco figured if the tube cage was already black, then this slight "burn" of the paint would not be as noticeable. I can't say whether this is true but check out the photo below. You can clearly see 5 blackened areas on the top of the tube cage that correspond to the location of the five octal tubes.

    Dude...Why would you cover a thing of beauty with ugliness.
    Of course my opinion.
    I do have cloth covers for my m125's but that cage reminds me of a ZOO.

    Liability concerns, perhaps? Remember that Dynaco was based in the home city of the Philadelphia Lawyer. What a Face What a Face

    It protects the tubes from falling debris.

    A friend acquired an ST70 in poor condition, has made a new chassis, including wood.
    I do not have the cage and he has given it to me.
    I will not use it, but I will save it as an amplifier component.
    My ST70 indicates on the Blackwood front, I think it must be black.
    I have the doubt to paint in black anticalórico and to obtain the logo of kevin, although I believe that said logo is of paper.

    Covers of ST70. Empty Label

    Hi Philo,
    If your referring to the Dynaco NOS black labels I sell....These are printed on a very durable vinyl like material with a peel & stick adhesive which after some (50) years is still tacky.

    I'm over (60) now and has been accused of being "Tacky" also....I'm old enough not to really care.

    Regards,

    Kevin
