Please make an offer.

  I have an 833 that shows continuity on the filament...only test I can do....that I would trade for something interesting.  No warranty beyond that the filament was good when it left here.  It looks clean to look at it, not burned.

    I have a good supply of 810's so I figured a pair will modulate one nicely.
    I like the BTA-500/1MX's. As a matter of fact, I was supposed to be wheeling
    and dealing on a -500MX with Eric, WB4VVI (SK) before he went SK. Oh well. I
    like the prospects of the 810's and the single 833. It won't weigh near as
    much as one of those boxes. I have some nice black krinkle panels so a
    krinkle motif is in the cards.

    There's a fellow near me that built a single 833 modulated by a single 833,
    one of a class A bias-changing heising design. I gave him a big reactor for
    it. I can get details if anyone wants.
