Source for 1N34 Ge Diodes?

[sfr]

Does anyone know where to get 1N34 Ge diodes?  

Also, somehow I ended up with a whole bunch of Zener diodes - something I don't use very often in most of the things I build - are these of any use in effects?  They couldn't be used as clipping diodes, could they?

I am pretty sure Mouser has 1n34's.
The zeners might be useful in reverse polarity protection I think.
I know nothing though so maybe I should keep my trap shut... :roll:

Hrm, look at that!  Last time I checked my catalog, I didn't see 'em there, but I just found them searching the website.  (the  wonders of technology!) Colour me embarrased.  

Thanks!

1n34a @ $0.17 ea.  Something like a $30 minimum order. Buy a lifetime supply - be happy for years to come.

Small bear electronics has a work alike in stock.

NOS Diode with no minimun order.

They work fine in my Shakka Braddah III (still on bread boarded begging for a good tone control - might go active 3 band).

Good hunting,

Circuit Specialists from Mesa has them for sale. Steve Daniels offers a workalike for a bargain price.

The workalike is the "NOS Germanium Diodes" from the stock list?  I think I have some of those in my last order, and I didn't even realize they would work.  I seem to remember thinking they were something else.  Once again, colour me embarrassed.  I'm going to do a better job researching my own question before I open my mouth again!

Don´t worry about this, I stepped into the same trap some weeks ago because someone here on the forum posted that Steve´s NOS Germanium Diodes are 1N60 workalikes. But I have the information from Steve himself, that they are exact 1N34A workalikes, so just throw them in and they will work fine.

Try here    http://www.web-tronics.com/    The prices are reasonable.  I've ordered from them in the past and haven't had any problems.  I wouldn't recommend ordering the pots - not very good quaulity but everything else I ordered was OK.

A month ago I purchased 100 of the 1n34a from Computer Controlled Automation Inc. (http://comtrolauto.com/). They are an opaque black color with white printing on the side. I thought the 1n34 was transparent. Do I have a work-a-like or the real thing?

I've seen 1N34 diodes that were painted but they were always glass construction underneath. See if you can scrape off the paint and see the body material. It is a point contact diode and should have a fine wire in the glass body making contact with the  semiconductor surface.  

You can measure the voltage drop across the diode to see if it is Ge. Put a 1k resistor in series with the diode and measure the dc voltage across the diode...    like this:  9v battery positive lug to 1k resistor to 1n34 anode,  then cathode (banded end) to the battery negative post.

Hey all,
I can get you all the 1N34a,1N270, and 1N60 diodes you want.
They range from $.12 each for the 1N34a and 1N60's to $.22 ea. for the 1N270's.

Email me anytime :-)

Peace,
Mike N.

It was paint, and it was glass with a little wire inside. Silly me.

You can measure the voltage drop across the diode to see if it is Ge.

I measured four of them per your instructions Jack. They came out .33 to .38 volts. A quick google search said 1n34 is typically .3 volts as opposed to .7 for silicon. That seems close enough to call them GE. Thanks for your help.

For those guys in the UK who don't really want to pay transatlantic shipping costs, http://www.bowood-electronics.co.uk/ stock 1n34a's.  Although the diodes are fairly pricey (£0.35 each, and a minimum order of £5.00), i've ordered from them a couple of times now, and their customer service is second to none (that i've experienced - i have yet to buy stuff from Small Bear - there's some stuff there I can't find anywhere else).

I found them out of a general longing to get away from using Maplin...I'm trying to lead a boycott of Maplin, purely because anytime i've had to use them, i've found them (a)unhelpful, (b)unknowledgeable, and (c)overpriced.

Just my tuppence worth...

http://www.greenweld.co.uk is another possible if you are in UK boycotting Maplin. Anyone hae experience with them? Possibly some useful surplus.
