Pics of electronics things laying around

Just crud some might appreciate or some understand. Kicking it off with some sorted Germanium for waiting to be installed in some gear we made. Going back a ways here.

There are still THOUSANDS of these 2N404's here. I could make a bean bag chair out of them.

Do you happen to have any ASY77 ?

I have been doing some simple experiments with germanium transistors and I like them a lot.

I once did a simple mono line amp and I was surprised what it did to bass and vocal, so I built another for stereo and was quite happy with the imaging and overal presentation just by introducing some germanium gain.

It was not a good circuit and after some time thermal runaway ended the life of my transistors.

It sounded great while it lasted...

I can take a look - that seems to be a VERY LOW hfe PNP transistor with higher than normal voltage limits. Like a small power transistor in a TO-5 can. I can look thorough the unsorted transistor boxes at some point. I do have ASY48 one of the bins says, I am not sure how many. The picture above are 2N404 - there are thousands (10's of) those here. There was a stretch of time here where we were buying ALL through hole transistors that the electronics vendors had left. RCA etc, was kind enough to list their distributors in the back of those old tube manuals, and come to find out (at the time) some of them were still around with inventory. There are more full boxes of unsorted transistors here than sorted ones. Enough to fill a car, and I am still looking, lol.

Was not really posting to sell, but I am happy to take a look for you.

Yes the higher voltage limits is why I picked it from my stash, I have a few and I am using it with an opamp design on +18 -18V so it can run from the same psu rails, as a buffer after an opamp to drive a small transformer.

So just in case you happen to run into a bunch, I will be interested in having some.

Whoops was selling a bunch of legit transistors - did you look at his list?

 

[PermO]

No I did not see that, I just looked in the black market, I don't see it there.

I'm not really in the need, but it would be good to have some extra.

Couldn't we design an all pnp germanium single 24V supply DOA to use them up?

Cheers

Sure! I have been sitting on them waiting for a worthy project. I am sitting on about 60 low noise 24V linear supplies too. They were getting too hard to find to throw them all into stomp boxes.

I am about to add another random picture I think - A Metal Knob 33609 just arrived to add to our collection.

 

[13engrsapper]

Just arrived - I hope to have time with it on the R&S Audio Analyzer in the next few days.

Not particularly directly electronic but it is an electronic art work that is on my office wall.

You can guess the artist.

I really like the idea of some germanium DOA's ...

Design the PCB so you can break it apart into indevidual DOA's to keep costs down.

This could be a very affordable project with cool sonic qualitys, I would defenitely want some, the GDIY germanium DOA

I love it

Last year with my youngest grandson Kash, and a newer 33609, and a pair of Fonia EQ's... Gotta start them early. I am sure they will never realize that most guys who WANT to touch and use this stuff never even actually get to see it in person.
