AC 128 replacement Fuzz Factory?

[Marbles]

Hey there :)

Hope you guys are somewhat recovered form Christmas..

I want to build another Fuzz factory, had built one before, but gave that one away. I could be crazy, but I can remember not paying that much for AC128s..

Musikding sells them for 2.50€ but they're out of stock. Banzai has them for a whopping 5,65€.. Each!

Now I might be cheap, but can't remember them being that expensive.
 
Would other germanium transistors have the same characteristics? I have a batch of GT308b/v 's laying around. Would they give me the exact same result or will there be very notoicable differences?

Are there better replacements?

Use sockets, and try your GT308s.

They might work fine, they might not - I've not used them in this circuit, so I really don't know.
Remember that Russian transistors sound as though their gain reading is far higher than they actually measure.

They would be a great low cost alternative if they do work though!

[Marbles]

Yeah.... A big difference in price haha.

Any other usual suspects I could try? I know the ac128 sounded great here, so I'd like to be close. (In other fuzzes I always thought: Meh.. But who knows, when they're obsolete they will probably be the holy grail-mojo tone transistor ;) )

Do you have experience with other transistors in this circuit?

[Beaker]

I'm afraid not - I've only built one (using AC128s), and I doubt whether I will ever build another.

[Marbles]

Haha, not a big fan eh?

I'll try them. If they're not as unstable as the ac128's, I'll try some others or wait till others have it in stock.

Thanks
