    Interesting --- if you look at the bidders, 20 of the 28 bids were from one person with a feedback count of 65 or a newbie.
    The high bidder had 779 feedbacks.

    Wonder what it will cost to get it working???
    Better them than me!!

    Hi. Just came across your posting, the cost was less than a dollar! I had to replace the shorted C27 390pf cap and the charred 47 ohm resistor.

    I have a st70 series 2 also that i just picked up.
    the board is nasty looking as it's had problems
    the bias leds aren't working
    1 bias set screw has broke of and another pot added in that place
    it works , but i would like to put it back to normal and ad some of these new mods to keep it from burning up .
    is there anyone making the boards for these ?
    does anyone have a board from one and willing to sell it ?

    I'm not aware of anyone other than Dynaco (Panor) that EVER made any boards for the series2.
    LEDs and trim pots are cheap, but using some finesse putting them in an old board may require some expertise.
