  2. Here is the data sheet for the part for all that are interested. http://www.philbrickarchive.org/pp55a.htm

  3. THis is one I have not seen before.. cool


  4. The Philbrick OP-AMPS that had two vacuum tubes (valves) sticking out of the top and plugged in were the first modular OP-AMPS and the Burr-Brown OP-AMP in the walnut box was really neat. I have seen pictures, but I don’t have any.

  5. I’ll see your op-amp and raise you an ADC.


    Came out of an ancient radiation field analyzer (along with, among other things, a lifetime supply of reed relays and 20-turn trimpots). Sadly I never found any data on it.
