Fuzz Face problem...

Hmmmm...I almost catch something, but I can't say that I do...the terminology is painting a too vague a picture for me to comment informedly.

eheh ok!  :?

I thought he said he was using a battery in the last thread.?

[Karmasound]

have you tried a different c3?

[HeaD]

have you tried a different c3?

no but i can try now, wait please

[Karmasound]

for the sake of simplicity just use a battery for now.

[HeaD]

Oh crap... I was sure that the problem couldn't be C3... i change it and... IT WORKS!!! sorry guys :/

[Karmasound]

ohh my lord !!

is it really over now!!? :lol:  :shock:  

just playing


you might have burned it up with the iron, or just got a bad one.



get the collector of Q1 at .5 v

and C2 at 4.5v



I think we all learned from this one :idea:

[HeaD]

Yeah, I'm so happy, in my place is too late for a good test, but tomorrow I'll close it in the box and I'll test it! Thanks to all!!!

I see two schematics on that AMZ page: 'Positive ground for the FF".
 I see Q1 Emitter connected to ground on both schematics.

You seriously need to get your eyes checked.  On the negative ground one, Q1E goes to +9V.

Seems you've got the problem fixed, but as you probably know by now, it's all about the polarity of your caps.  The + end should be at the base of Q1, with the other cap's + end to +9V.  If that doesn't work, your transistors won't take the reverse voltage.

Schematic reading ability anyway...daft no ground symbole there ...  :oops: .

Head, I apologize for my forceful contention about Ground at Q1E on a FF.
 However I also feel if you actually Gnd that point, [actually convert the PNP transistors you have into a Pos Gnd FF Circuit] that it HAS to work.
 The neg gnd PNP FF's...I have seen mixed feelings about them at best, now somehow [IIUC] Dunlop and others have figured out a PNP POS scheme that does work, I believe Jack Orman has one, I don't know what the secrets to that actually are.
 I've only read about these FF problems, but have built many with Q1E at ground that fired right up.
 If you figure out the Pos Gnd PNP thing let me know what did it, It's a 'trick' I haven't seen a sure fire method for yet...I've heard it can be done, but mostly I've read about those who have gone with the traditional scheme to cure FF circuit board Ills.
