Suggestions for

So I got m a dirt cheap batch of 50 NOS Rushdy Ge PNP transistors these things are mint and look cool, low leakers but only 30-50hfe.

Really wondering if you guys have any suggestions for what they might sound good in.  I have the bread board at the ready and going to make something right now.  I am thinking a rangemaster might lend itself to them if biased right... What about a low gain Fuzz?  anyway welcome to ideas

Try it in fuzz face style circuit for a dirty booster. Worth a try.

I used some low hfe OC45's in a fuzz face. Sounds cool.

Will try that just soldering up a proper FF right now just etched a tiny board

Set them up as a FF, except use 4 transistors... 2 or the 30hfe in darlington config for Q1, 2 of the 50hfe in darlington config for Q2...or add a PNP silicon boost stage in front, Kinda like this.....



++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

Rangemasters for the 50hfe, or "darlington-ize" for more gain

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

Rangepig with silicon / germ

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

use as diodes

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

make "resistor men" using them as the "head" .....  http://www.instructables.com/id/Resistor-man/

Well, bout a year ago I built a FZ1A and one or 2 of the trannies were low hFe, so, try it that circuit, it does sound really good. Do some bias.

Dragonfly you came up trumps there!  I shall try that!!  Only bummer being I am at work now   And I really need to put my spare time into playing my axe this week.... got a dressing down from guitar teacher today about not improving,  its hard doing 55hours a week at work having a girlfriend and building effects.  So effects are taking a back seat till the weekend. probably sunday then I can have a build again.

Slideman whats the FZ1A?

I've built Rangemaster style boosters with low gain Russian transistors and they still had plenty of boost.

Well, breadboard it first...its an idea, and it will still need some tweaking possibly...though it should be fine. If you're a "more knobs" guy, theres plenty of things you can incorporate....disconnect lug 1 of the "gain" control (which will make it more of a "soft control / impedance matcher"), replace the 68k with a 100k pot (boost control), replace the "bias trimmer" with a 4k7 and 10k pot in series, use a more traditional "fuzz" control, etc, etc....

Slideman whats the FZ1A?

Maestro FZ-1a...

You should be able to find a schemo for it...but if you like vero...
