[sdiy] Anyone need any transistors? I got lots and lots...

[Aaron Lanterman]

I'm finally (mostly) finished obsessively and compulsively sorting through 
the pile of transistors and other stuff that my dad brought on his last 
visit, which he had inherited from my grandpa. I have them sorted into 
plastic baggies.

Quick question: If something's tagged as "RF" "UHF" "VHF" etc... is there 
any reason I couldn't use it for audio (although it might be overkill?)

There is more here than I could ever imagine using, and I'd like to see 
them go to good use. So if you see something you need for some obscure or 
not-so-obscure purpose, such as a repair or a circuit you want to build, 
make an offer - probably would be best to get a bunch of stuff to make the 
shipping worth while.

If you see specific data listed (hfe, etc.) that probably means I got the 
info from Roy Tellason's page (great resource!) and couldn't find a 
datasheet for it.

http://yourpage.blazenet.net/rtellason/parts.html

If you see a vague description and a tag (data?), that means I got the 
vague description from www.datasheetarchive.com, and couldn't find any 
further info. If you see a vague description and no tag, that means I 
either found a datasheet online (usually from www.alldatasheet.com) (or 
else I forgot to add the (data?) tag.)

There is some rather weird stuff in here, like unijunction transistors, 
and a bunch of germaniums (maybe I should start a fuzz box business), and 
a tetrode switch, whatever the hell that is.

Also, note the "mysterious" sections - I have a _lot_ of some of the 
mysterious items and would love to know what they are...

There were some other items - some other 74 series, a bunch of LM324s and 
LM318s, a couple of LM380s, that I'm going to keep for myself... but the 
rest is all up for grabs. (Note that these parts are of varying age, many 
decades and decades old, and some of them are "pulls," and some look like 
they were never used but still look beat all to hell. If you find 
something interested in, I'll give you more details about their 
condition...)

Lots of mysterious large flat mushroom old Fairchild ICs

Linear IC cans:
I could find datasheets on the CA3035 and CA3018 online, but nothing else...
CA3005 RF-IF amp (1x)
CA3007 single-channel audio power output amp (1x)
CA3013 gen purp video amp (1x)

TAA293 single channel audio input preamp 
NS LM272 - I found a L272 datasheet, but it's in DIP type packages...
this is a can...

Logic IC cans:
HEP580 2-input NOR (2x)
HEP583 single JK flip flop (2x)

Voltage regulators:
MFC4060A (tons)

Some Logic DIPs with an S logo:
(Michael Baxtor suggested these are part of a proprietary Signetics
TTL line from the 70's, and that they should work fine with SN74 series
logic)
N8416A 3-Input NAND-Function Logic Gate (4x)
N8270A 4-Bit Shift Register (2x)
N8826A Dual J-K Flip-Flop (2x)
N8266B (?) (2x)

Resistor-Transistor (?) DIPs:
(Michael Baxtor suggested Plessey RTL or DCTL from late 1960's - the
one datasheet I could find had RTL, so they're probably RTL)
SP321A Dual J-K Flip-Flop (1x)
SP328A Dual D-Type Flip-Flop (2x)
SP362A Single Monostable Multivibrator (5x)
SP380A Resistor-Transistor quad 2-input NOR gate Philips (6x)
       (found a datasheet)

Motorola Logic DIPs:
(Michael Baxtor suggested MC7XX parts are RTL from late 1960s. Roy
Tellason suggested that the DTL parts should interface OK with modern
TTL, but the RTL parts probably won't)
(Also, Steve Ridley and Kevin Lighter noted the 717, 719, 778, and 793
are used in the Moog sequencer)
MC667P Dual Monostable Multivibrator (4x)
MC717P 2-Input NOR-Function Logic Gate (1x)
MC719P 4-Input NOR-Function Logic Gate (5x)
MC725 (handwritten) 4-Input NOR-Function Logic Gate (1x)
MC778P Dual D-Type Flip-Flop (5x)
MC789P ? (5x)
MC790P ? (1x) (dual JK flip-flop - from online forum)
MC791P ? (1x)
MC792P 3-Input NOR-Function Logic Gate (1x)
MC793P 3-Input NOR-Function Logic Gate (2x)
MC830P Diode-Transistor 4-Input NAND-Function Logic Gate (10x)
MC846P Diode-Transistor 2-Input NAND-Function Logic Gate (1x)
MC894P 4-Bit Shift Register (2x) (probably DTL)
MC9820P 2-Input Multifunction Logic Gate (2x)

Several list members noticed that by biasing things correctly, you could
run the RTL chips in a linear mode...

Apparently Craig Anderton used one in something called a Timber Gate - I'd
love to have a copy of that article if anyone has it...

Well, there you go! Somebody please take some of this stuff off my hands 
and put to good use...
