Re: Caline CP-32 Clear Veil Overdrive Fuzz

I bought some higher quality electrolytics for this, a 2.2uf and 22uf nichicons. Not a lot of difference but quieter. As with the puffer fuzzes I bought, the input jack/circuit board has some issues and I had to resolder it to get rid of the excess noise and intermittence. Once I did that, it now so...

Re: Caline CP-11 Puffer Fuzz [schematic]

The transistors have around 230hfe in the 2 I bought now, they both seem to have issues with the circuit board too and the soldering on the input jack. I've had to fiddle with them both to get the noise down, bad connections.

Re: Moen - Jimi Nova

Can you tell me what value C2 and C4 are, C2 in mine is .047uf which is wrong and it should be .0047uf, and C4 is missing (470pf?)

Re: Maestro Envelope Modifier - ME-1 debugging

Yes and the schematic is for an older version of the Envelope Modifier, so this particular version of the Envelope Modifier needs to be traced.

Super easy to add a tone control to that and make it into an overdrive with a couple 100k pots.

Re: Caline CP-32 Clear Veil Overdrive Fuzz

I got an Atlas DCA55 for xmas, so I measured the hfe on the transistors in this. They are both 346. Those are some hot 3904's, I wonder what brand they are.

I replaced them with some Fairchild ones that have 200 hfe, it sounds better but not by much.

Re: Zonk Machine - why can't I get my OC44 working?

The schematic seems incomplete to me and there should be a resistor between -V and the base or one between the base and collector.

Re: Caline Fuzzy Bear

Yes, it's pretty standard stuff C5, as it's in the power supply section and is slightly larger and I think it is 100nf which is standard filtering there. C6/C7 are not, and appear to be in the pF range (they are same size as the 20pf cap) and well away from the power supply cluster. I'll take some s...

Re: Caline Fuzzy Bear

It's common practice when designing low noise smoothing/decoupling circuits. One will be an electrolytic, good for smoothing out low frequency (ripple) but less so at high frequencies, the other a ceramic to catch any spikes that the electrolytic lets through. They are both very small capacitance v...

C6 and C7 are also strange to me, they are right next to each other on the circuit board, I see no reason for them at all.

Re: Caline Fuzzy Bear

what's the purpose of C9? I'm guessing just to stabilize the voltage drop across R7. Battery sag emulation I guess? Yes it's just a Fuzz Face clone, and no it doesn't oscillate, it's sounds awful though. I suppose if you like fuzz that gets really compressy when you hit the notes you might like it....
