Know a PNP from an NPN???
 

Mutch less a TO3 from a chip???


jest curious.....


show me....

+ or - trannies, regardless from a carrier package,
they're both available in the many cases.
TO3, TO92, SOD, SOT, SSOT. 3,5 or 6 pins (for dual units),
SO6, SO8, SSIC, blah blah blah.

I knew a girl with an STD.

Does that count?

Didja hit it?

Yes, she said **** me and make it hurt.

So I did her and then hit her with a brick.



Credit I think goes to an old Andrew Dice Clay joke.

Yes, I know the difference but have largely forgotten the details because I haven't had to pluck out the correct transistor from a parts bin to solder into a board in a few decades. But if I had to do it again, I'd make sure it was right.

Some of that custom 'tronics I built for my Vette console, I dunno where any spare parts are for it now.....some 24 years later......

Digikey.

N and P signify polarity of the bipolar junction transistor. NPN is "negative polarity" and PNP is "positive polarity". Basically which way the current would flow (to the emitter for NPN, from the emitter for PNP) when it was turned on. There are a lot of different types of transistors though, and they don't all have this sort of designation. I always considered NPN to be "typical" because PNP types were ass-backwards from what you normally wanted in a simple amp circuit or switch.

do you know MTV from VH1???




do you know a FET from a SCR???

You guyz pulling up so many old lektronic terms, shit I not seen since maybe 35 years now......and certainly not messed with since doing my console in the vette....

TV channels......

Field effect transistor.....VERY high input impedance....

Silocone Controlled Rectumflyer......

Here. Lemme kontribute something worthwhile; Tubes sound better than transistors, static electricity ruins my hair.

A LOT of folks claim that is true, but that is totally subjective opinion, not backed up by lab research ......

and May I suggest the static got to your brain???

:rofl:

fixt

RONG. :Jeff '79:

Even clean tubes sound better. :yesnod:

Oh the horror!

:lol:

I used to fix Color TV sets at a static charge of 30 kv..on the pix tube and ASSociated generation circuits....running off the flyback transformer from the horizontal scan frew of 15730 hz......15750?? been a while....

at any rate the voltage was shocking......and so many of my memories are kinda subject to pulses......nuff said.....


:issues:

We know. Trust me we know.

:rofl:

Here is a guy that knows his stuff and describes it in simple English. The last time I took electronics was way back in 1972.

Testing & Replacing Output Transistors

Hmmm, wonder what Fran looks like naked in bed?

Why, yes, yes I do.

a sine wave... is a sine wave... is a sine wave; unless you like one sources doctorization of it over the other.

If that's the case, then "clean tubes" :rofl: are not clean at all; altering the AC's input signal waveform (maybe to something more pleasing... I'll give you that). But then "clean" would be opposite of the word you'd used to describe what your ears hear.

Thing is that in order to drive a speaker system tubes need an output transformer, even if a cathode follower, and such transformer has to be bifilar wound for max effectiveness of the sharp/square edges of some music.....there are all sorts of krazy amps being built, even today, and most of the vacuum tubes are made in Russia/eastern Europe.....

Probably a lot like VegasJen... :leaving:
