  1. Anyone would care to post smoe part numbers for obsolete (not selling
    currently) electronic parts, thanks

    smoe ?

  3. Sorry for the typo, I meant some

  4. 1N829A

    see also ;-)

    Hope This Helps!
  8. Come now, those are unreasonable old parts.
    How about uA703 and later, the uA709 opamps.

    Howabout 6SN7, or 6L6, or most any other tube number.

    I have never found datasheets for either of these.

    Service to my country? Been there, Done that, and I've got my DD214 to
    prove it.

  12. Thanks gents. I used these terms to see if any more spammers come up
    in the first pages, which they did not. (some of these parts have a
    large following and a lot of history, wikipedia articles etc, there
    are of the kinds where spammers would not come up in first pages
    anyway. But some parts were rather rare).

    ouch. ;-)

    Well, gotta give 'em some credit... they're starting up a new factory
    in Elbonia based on the new unobtanium oxide semiconductor
    manufacturing process.


  14. Would that be the UHF FET a friend of mine is lamenting?
    He builds RF sniffers used in transmitter hunting for which
    he's bemoaning the absence of a credible replacement GaAs FET,
    and can't achieve the same noise and dynamic range performance
    with any of the UHF chips.

    Probably. Its reverse capacitance was so low you counld make a 70-dB
    isolation amp at 100 MHz in one stage, with one FET and two
    resistors--you just connected G2 to source, and away you went.

    NEC makes two dual-gate gaasfets, NE25139 and NE25339.

  17. That's what I *love* about Usenet. I figured if anyone had an answer
    for Bryan, it would be Phil or you, and *both* of you answered! I'll
    forward your response to him and I hope it will solve his problem.
    If it does, you'll have his eternal gratitude!

    The mrf966 depletion-mode dual-gate GaAs FET claims Crss
    of 40fF, typ, damn good, whereas the NE25139 and NE25339
    are even better, 20fF. But I see NEC's specs are all with
    Vg2s at +1V, a bit of a pain with the bypass requirement,
    etc., compared to 0V ground used for the mrf966 specs.
    John, have you tried using the NEC FETs with grounded G2?

    Don't forget AC128 and AF115. Which reminds me, were any ICs made of

    - YD.
