Analogman - King of Tone [traced]

- the input cap is 22n on both sides
- instead of 1s1588, this uses 1n914
- output cap of the high-gain red side has an "H" painted on it, but is the same value 105 as on the yellow side.
- the feedback loop cap on the yellow side ist a weird value. 505? The red side has the usual 101=100pF.

I haven't verified all of the resistors.

Am I correct you are not joking?

Haha you are correct, however, I did not WAIT 7 years for the pedal. I just didnt decide for 5,5 years if i wanted the pedal. But when I did, they sent it the next day

Pfoooh

Dirk,

what do you reckon is up with this 505 cap?

That should be 5uF, but that doesnt make sense?

[Motter]

Maybe it's a 50 pf and the second 5 is a tolerance marking? Or maybe an S? Can you see any other markings on it?

[Seiche]

That's what I'm assuming, but it's not consistent with the other one (101).

Wow, same happened to my fallout character when i maxed his social marketing bullshit instead of soldering.

So I traced the circuit and it's pretty much what we already know. The only differences are thus:

- the input cap is 22n on both sides
- instead of 1s1588, this uses 1n914
- output cap of the high-gain red side has an "H" painted on it, but is the same value 105 as on the yellow side. The IC also has and H painted on and the chip id sanded off.
- the feedback loop cap on the yellow side ist a weird value. 505? The red side has the usual 101=100pF.
- On the high-gain red side the gain resistor is 100k, on the yellow side it is 1k.

I think the last part is news, as this resistor was always assumed to be 10k and the gain pot changed for high-gain on DIY projects.
