    unknown control board

    I need to identify some boards I've got from a radio broadcasting station. I gather they are some kind of server boards from the late 90s - early 2000s but the coding on them doesn't help to find out what they are. First I just wanted to cut off the gold fingers and depopulate the yellow ceramic tantalum capacitors but looking them over it occurred to me that this boards may have resale value as a whole thing. The only problem - I don't really know what this boards are. There are two versions, as seen on the picture. Any help with the identification would be greatly appreciated.

    They are video-audio boards produced by Leitch ... probably from the MXA, VEA, AMD, and/or ADA series ... I can not identify without clear board numbers.

    Thanks for the help. I would never guessed that they audio/video cards, I thought for sure they are some kind of telecommunication cards. I've got more pictures with what looks like model numbers. I didn't take pictures of the opposite sides since there is only soldering there and the stamps of QA.

    Just a tip for you. Whenever you see an adjustment with the word GAIN, that will be an amplifier circuit.

    At least now you have some info from RLS to see if there is any resale value. If I were sending them fr scrap I would definitely snip those TCs. Good luck.
    Copper, brass, and Leather. 3 of my favorite things.

    In these situations, is it better to desolder the Tantis? Or to just snip them off as Hipogear mentioned?
    There's extra weight in the legs but I don't know if there's any Tanti in the legs either.

    Those boards value seems only to be the Tantis, the Gold fingers, the few IC chips & Copper backed power transistors.
    This might be a situation where it comes down to 'Your Time = $$'. And 'Postage weight costs you $$ too'.

    I actually snipped off and cut in a half almost every piece on my sample board to see what's inside. I ended up collecting just like you've mentioned the gold fingers, IC chips and TCs. RLS0812 pointed me in the right direction with the manufacturer's name so I looked up the prices on the Ebay. I was very pleased and surprised to see what I saw although the stuff being sold on the Ebay seems to be much more modern from what I have. Still, if I can figure out what exactly I've got, I will post them on Ebay instead of scraping them. Now if they don't sell in a year, only after that I may scrap them for the valuables.
