A sexy ID thread

[stonerbox]

Yay, another one of these threads!  I'm surprised that we haven't dedicated a sticky where people could post pictures and ID components.

Oh well, I savaged salvaged some diodes and trannies from an old 50-70's radio and I couldn't find any info on two of the transistors and one of the diodes. What could they be? PNPs, NPNs, Germaniums? The gray ones are definitely silicones. Go ahead and ignore the bottom two since they are well documented.


Gray transistors:
C06D
EMC07

[Russian] Metal can transistors
2x rT322Б1 VII 75

Diodes:
WF 2GA 113
GA101 ( found info here: http://www.radiomuseum.org/tubes/tube_ga101.html)

Nice!  You will use it for pedals? Amplifiers? Some great things to breadboard!

I like your attitude!

Well that depends on whether I know what they are capable of. I don't want to stick the four legged russian transistors in backwards and risk damaging them.

good work pulling out some NOS parts ! you need to get some sort of test equipment like a peak atlas . it will tell you if its shorted, junction type and voltage drop between base and emitter which I believe is the forward voltage or hfe? I am still learning lol  but that can tell what class to put them in ..like out of spec high/low , fuzz face, booster etc

put an analyser on the diodes and if its around .3 its germanium and if its around .7 forward bias voltage its a silicon diode ..a peak atlas with identify anode and cathode leads as well if they are unmarked

because I was having russian troubles, and because italianguy63 showed me to this link:

http://www.datasheetarchive.com/dl/Scans-048/DSAGER000621.pdf

I can tell you that the "GT322" is on page 39. C06 and C07 are both "good luck".

Those four-legged creatures remind me of dual gate fet's. They're found in older Kustom amps for switching.

I have some new dual gate fets kicking about. I wonder if they could be used to make a booster, or fuzz?

rT322Б1 = ГТ322Б1 = GT322B1

[garcho]

could those non-Russian transistors be gallium arsenide?

Galluim arse... say what?

Still not sure on pin-out of the GT322s. Duck gave me the proper documents and I've been searching on my own but no luck and my multimeter does not show any hFE on them. However, the AC188/187 (PNP) measures fine and has a hFE around 350 and 400.
All diodes measures .3 to .4 so they are germaniums.

Edit:
Got reading on the gray transistors now, both are NPN.
C06 - 115 hFE
EMC07 - 237 hFE

GT322



K = Collector
b = Base
3 = Emitter

The Cyrillic word on the fourth pin is pronounced "Korpus". The fourth pin on the GT311's is labeled the same, which I believe goes to ground for noise reduction. It's connected to the transistor casing.

Thanks man! Love your videos. How much did you pay for that S3N Super Flutter?

Turns out the three of them are pretty low hFE (63, 77 and 105). Guess I'm building my first PnP fuzz soon.

[PRR]

> "Korpus"

Just like the murder movies. Corpse. Body. If it was a vampire you would stake the body to ground so it didn't make trouble. Being a metal-can body, you could say "case" or "shell". Radio signals leak easy, and (as you say) case grounding helps control that. Mostly insignificant in audio.

[duck_arse]

the "emitter tab" is a truly wonderful thing. knowing one pin is case can't hurt either.

and why gallium arsenide?

[digi2t]

No Problemo! Glad I could help. Thanks for the kind words for the videos. I enjoy doing them.

The Super Flutter was somewhere in the $300 range. I can't remember exactly, but luckily, I got it before the Canadian dollar tanked, so it wasn't as painful. This was before they set up they're international web shop, so I had to go through Zenmarket, which is a third party purchasing agent for all things Japanese, so that added some fees to the whole exercise.

I really love it though, it just does speed up/slow down tape stuff, as well as freezing, amazingly well. I started translating the instructions for it while back, but never finished. I should get it done though, because it doesn't look like they're anywhere near getting an English manual out any time soon.

I have heard of Zenmarket but only used White Rabbit in the past, which is in my experience a great third party purchasing agent. Don't know which of them is the less expensive, though.

I was thinking of getting one but to my dismay I found out yesterday it has been discontinued on their site, damn... I needed one to be able to play a guitar part live, off our upcoming album. It is supposed to grab and hold every first hit of a note and repeat it until I step off the hold button. Guess I'll will be forced to keep an eye out on Ebay and just hope that somebody eventually will put one up there.

just DIY one, look, i found a schematic online:

Really? I'm looking at the S3N web site shop right now, and as far as I can tell, the V2 is still available. $298 + shipping.

I was looking at an older version. Great!

garcho, I appreciate your help but that's a not a Super Flutter. Me and Digit has gone way of topic here.

i was making a joke! i doubt there's much in the way of a DIY clone of that flutter pedal. the schematic is the LPB-1. guess the joke wasn't so obvious
