Bajaman can you upload your schematic as pdf?

Thanks you all for putting the schematic from my crappy handwritten drafts in a software. I just hate doing it for some reason. But I can trace all day long! That is the fun part for me.

Was just waiting until the correction were released.J0K3RX wrote:What, nobody made a single layer through hole yet? Is it because it doesn't have Wampler tattooed on it?
Don't make me do it! We will be debugging till the cows come home...
I'll finish it after work today. Just a bit hard to make out what's going on with the power network, I usually prefer to use Net labels or Voltage reference symbols for that sort of thing, so it was a bit harder for me to decipher it.

Azrael,
Here is the PSU in an easier to decipher format.
I already posted that before, but actually I forgot the 4007 in series with a 47 ohms resistor. There are 2 4007 diodes in the PSU... Good polarity protection!

This is a new version with implemented corrections. Points 1-5 are connected to ground, IN-input, OUT-output, IN1 and OUT1 to insert out, the T1 Tight pot, G1 and G2 to gain pot, G3 and G4 to gain pot other sections (both at Gate SW also), TO1 TO2 TO3 on Tone pot, TH on Thrash sw, V1 V2 V3 the Volume pot and
+9 V power supply.
+9 V power supply.

I will post complete files including gerber files etc. once layout is deemed to be correct - I will probably adjust the dc socket footprint for a 2.1 mm standard DC socket in the final draft.
here is a composite of V0.9
cheers

im not accustomed to the way bajaman drew the PSU.
so here is one for those who are like me

Can you do double sided etching okay Jim
and you may not like my latest schematic euronymous0001 but at least it is correct - your one has at least two errors in the layout and component values ( and it is almost too small to read ) hint 15k resistor should be 1k5 and the second filter to ground in the notch section is connected wrong
