1N60P diodes

[MmmPedals]

I ordered 1n34a and got these guys instead. both germanium. I guess they are probably interchangeable but are they the "same" for stomp box applications or would there be a difference in tone (primarily for clipping but curious about all applications)?

Many different things were sold as "1N34". For 9V audio stompboxen, diodes originally marked "1N60" will be equivalent.

When I was building my D+ I tested aa117, oa90, 1n60, etc. They sounded slightly different, probably the different forward drop.

I have those new 1n60 looking like 1n4148, and old ones. The main difference between old and new is reverse leakage.
I tested many diodes to find the correct one for my TB3 using this simple arragment:
vcc > 1k > reverse diode > gnd, DDm across the 1k.
New 1n60 read almost zero voltage drop across the 1k, but old ones read as high as 100mV, ie, 100mV/1k = 100ua.

Did you buy them from Futurlec by any chance?  Same thing happened to me.

[MmmPedals]

yeah it was futurlec. guess it wasn't a mistake. i had a feeling it was no mistake but i dont mind if its equivalent.

I didn't mind either because I wanted 1N60Ps as well, but I emailed them a month or so ago saying that last time I tried to order 1N34As they delivered 1N60Ps instead, and although I wasn't bothered about it I would actually like the 34s, so I asked if I were to order again, would I receive the correct item.  I never got a response so I suppose that answered the question.

I did get some correct 1N34As from an eBay seller and there are differences between the two types of diode.  The forward voltage is different, although the audible differences to most people will be subtle I suspect.  Like everything else though, it's nice to have a selection on hand so you can try out a few in a build and choose your favourite.

From what I understand, there is a silicon 1N60P Schottky diode that is meant to replace the germanium 1N60P.

You may want to look into that, in case the 1N60P you were sent aren't germanium at all.
