heres how it should be wired....

I put that pcb in breadboard, input of PCB i connected to one jack, output to 500k pot and output of pot to anothe jack and firstly I had clean signal, I measured collector voltage and it was above 9V and then I unplugged in and out, measured voltage and it was around 3V so I change resistor in second transistor from 10K to 5,1K and it went to around 6V, then I plugged in and out and it was back above 9V...

have you got any stripboard?

if so, here is my original layout.

I dont have stripboard, just protoboard but I made layout by your schematic, maybe this will work better than layout before...

cool......

let us know how you get on...

Does it look ok? Ok, maybe tommorov I,ll try it, I hope :/ But thanks a lot

connect the other 10k to 9v.... and add a ground on the bottomn of the diode...

Ah sorry, I was moving with resistors so I forget to make line to second resistor...

And one more question, you said that 1uF cap should be nonpolaryzed, what will happen if I use electrolyt?

Great uncertainity concering its leggings..

P.S.
Electrolytic capacitors aren't necessarily polarized..
(at least, for a couple of μF values..)

Ok I made it and its just amplifying, I used blue LEDs instead of yellow

Domin · « **Reply #411 on:** August 23, 2020, 03:13:28 AM »

I put yellow ones and no change, when Im no playing I have only some hum in really low pitch

Show us a close up of your breaboard....

Domin · « **Reply #413 on:** August 23, 2020, 03:57:08 AM »

Sorry but I dissasembled it...but I checked it twice with my father and it was ok...I tried simple bass fuzz but it had same problem, just amplifying and not distorting...

deadastronaut · « **Reply #414 on:** August 23, 2020, 04:15:22 AM »

Hmmmmm wierd that its happening with 2 different circuits....

If i get a mo i will draw up a breadboard with the xfuzz on ok.
And we will go from there.....we WILL get this bugger going ok.

Ok, thanks, but I dont understand it, I would understand if transistors were bad, but they are conductive from base to collector and from base to emitter and voltage is around 800mV, one side has more mV than other, but maybe only 20vM more, I tried 2N5088, BC549C, BC547C and same...Collector voltage is only 25mV lower when I put 100K resistor instead of 10K, something is making problems and I dont know what...

Indeed, very strange......

if that bazz fuzz failed....

can we have pictures of your in/out jacks that you connect to your breadboard?

Domin · « **Reply #418 on:** August 23, 2020, 05:24:24 AM »

Bazz Fuzz I once made with 2N5088 on breadboard and it was working, so I made it on PCB and its great, then I started to have problems with effects...

Probably i found what was making problems

Edit: I used 100nF cap in clipping section but its working!!! Noe i need to find why my pcb isnt...

well at least you have something working yay........
