Clipping Diode ID

[selfdestroyer]

I got home and looked at my diodes and I have a bag of IN914s from tayda that look identical...

Thanks for looking, I guess the "70" screenprint is what's throwing me. I'm breadboarding up something tonight to mess with. I got the mosfet boost done, now on to the 808 part.

D3 and D4 look like 1N4148 to me...

I think you're right. I just tried a few 1N4148s symmetrical and they do sound great. Thanks AlanP

Do you think the water clear LED may be on the Drain and Source of the mosfet clippers? I never seen LEDs in asymmetrical before but I have seen an LED with mosfets before. hmm.

My guess on those would have been BAT 85s.

They are 1n914, pretty sure, from Tayda...like the others said. I even pulled some out of a TS9 from the 90's that looked like this. I've found that 1n4148 diodes tend to look like the others in the picture.

You can't ID an unmarked diode from the package. There are literally dozens of diodes made in any given package. Just because Tayda sells 1N914s that are colored and shaped like that doesn't mean that the diode is a 1N914 from Tayda, or a 1N914 from somewhere else. You have to desolder it, measure the forward resistance, and then lump it in with the inevitable dozens of similarly measured diodes ... basically, what I'm getting at is that you aren't going to ID the diode itself, but you can at least determine its function in the circuit.

Makes sense Jon, thanks.

When looking at what diodes are used in 808 mods these days, it gets me close to IDing them. I'm sure they used standard clipping diodes and nothing rare. It's a great sounding pedal for a modded TS and I really like the options of the input cap selector and diode selector. Now I wan to see what IC they went with, if it's the standard 4558 or one of the variants.

Reminds me of the VHT V-drive

11 diode options, 12 input cap options, was a really nice pedal, too bad I sold mine, but it was in the "I can build better" section of my board.

OK, found these in my stash.  FV a little high for 1n34a

Thanks so much.
