Anyone nice enough to tackle turning the cosmo into a LM?

I'm not the best with schematics- but I'd be willing to sweeten the pot with
1) good vibes
2) 5 dollars via paypal (sorry, it's all I got)
3) buy you something at mouser (it's in my hometown) and save ya some shipping?
4) offer you advice on how to raise a dog?


You guys are the bomb!

workin on it!!

First I compared the guitarpcb, skreddys LM and MB cosmo schems to verify their topology is the same. It is the same with a few parts omitted and some value changes. Ill just list the LM values. I used the component numbering from the cosmo. I'd double check it cause I could have a made a small mistake.

R1 1M
R2 omit (skreddy schem this is a 56k labeled R8) maybe socket and try it with value then jumpered
R3 100R
R4 470K
R5 10K
R6 820R
R7 100R
R8 56K
R9 100K
R10 56K
R11 10K
R12 2K7
R13 omit

C1 10uf positive facing Q1
C2 100pf
C3 22uf (100uf on skreddy schem)
C4 5.6nf
C5 220nf
C6 4.7nf
C7 470pf
C8 220pf
C9 220pf
C10 22uf (100uf on skreddy schem)
C11 15nf
C12 3.3nf
C13 2.2nf

Transistors all Bc109, omit zener diode over Q1. Q1 will have collector touching C2/R5 junction and emitter goes to 680R resistor. There is also a 100k resistor after C1 but before Q1 if you look at the schem. It goes to ground and I'm not sure if its important. Maybe someone else can chime in on that one. Also the electro on the gain and fuzz knob are different between the two schems. MB has them at 100uf, not sure why but maybe someone else can answer.

I love my Lunar Module clone!! Its one of the best big muffs Ive built so far.
