Need a few obsolete part numbers

[Ignoramus19284]

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

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.

NEC MC-5800

RSPR MV7780

I have never found datasheets for either of these.

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.

MRF966 dual gate GaAs FET

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.

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
germanium?

Yup--and don't think past tense:
