Pearl CH02 Chorus PCB

[Sylvain Ramone]

hello!

Newbie here, I wanted to share the Pearl Ch-02, it is the first time that I make a PCB from a schematic.
My notes:

- I omitted the entire sw-1 board as well as the capacitor C3 (1uf) and R4 (100k), also with R45 (100ohm)
- The main thing, seeing a post from Aion  (https://www.diystompboxes.com/smfforum/index.php?topic=110616.0) and other chorus pedal schematics (arion sch-z, Boss CE2) is that resistor R19 (56k) connect it to ground instead the schematic said (at 9v) It was the main problem since it didn't work for me at first and works when i ground it
-The original IC4 is a TL022, I didn't have it so I tried others. Worked for me: TL2262, TL062, LM386 and TL082, (not with the 1458) but I liked it better with TL2262
- as for the trimpot, use a 50k one, i leave it at 2.7v for pin 2 and 3.8v for pin 1
-R0 is a 1M resistor
-for the capacitor C18 (0.47uf electrolytic) i use a 474 polyester
-The transistors that i choose were for Q1,Q2,Q3 2n5088 and Q4,Q5 2n3904
- The dimensionsnare aprox 67 mm x 58 mm
I think I will continue with the Flanger Fg-01 version, since it is quite similar to this chorus
Enjoy it!!
Greetings

Nice work!

That schematic *is* very reminiscent of the CE-2, isn't it?!?
