hey folks,
i have a lot of 2n3906 trans left over from a project and i want to do something with 'em... does anybody have any ideas on a project i can build using these? thanks, jon
Simple boosts? There are so many things you can do with those.
I always figure if nothing else, no matter what the transistor, I can make a single-transistor booster.
well what do you want to do a gain thing a eq a phaser what.. you could do most anythign you want with it. a little practive amp
thanks for the quick replies.... i'm kind of a newbie, so probably NOT an ada flanger or sansamp! maybe a boost or drive...
i just haven't found many pnp projects on the usual sites. ideas or schematics greatly appreciated! jon
Id be interested in an eq thing. Ideas?
Hello Hullo--
Hey Jon, how about some kind of single-tranny booster? [LPB-1, Gus' NPN Boost, etc....] Check around in the "Schematics" section. {Actually, Aron did a step-by-step tutor session on the NPN Boost at the top of this forum.] One good thing about these is that they are "Fender amp friendly". Some of the Fuzz Face type stuff doesn't play well with Fenders! [Having said that, maybe you could throw together Jack Orman's "Yaff" Fuzz using two 2N3906's.........low gain trannys sound REAL GOOD in Fuzz Face circuits!]

Convert any NPN transistor ckt I know of to PNP...just change the battery, and polarized capacitros, and diodes [invert the polarity] check out the reads around here for more ingo
thanks for the info...i didn't realize it was so easy to covert npn/pnp designs. i'd like to try a rangemaster style build.
joe gagan has alot of 2n3906 based circuits.
Hello Hello Jon--
The Rangemaster / Treble booster circuit is not really "Fender Friendly" [At least not with the amp set-up you've got]. Try a more "full range" booster like a LPB-1 or NPN Boost. Also, the transistors you've got [2N3096] lend themselves more to a full range booster. Save the Rangemaster-style build for a good germanium [or, a well thought out and correctly biased silicon] tranny!
Brian.
thanks brian. i'm going to try the npn boost (pnp boost!) with the extra eq circuit at the end. by the way, do you have a local source for germanium transistors? jon
