Skreddy Lunar Module

Very much like the screwdriver except for 3 high gain BC109C's.

The very first Screw Driver prototype used all BC109C's as I recall. This was before I decided to do away with having each section of the circuit individually switched.

At one point I began using Mena Suvari inside, but that quickly became too expensive.

Do you now manufacture in Mexico like Fender Skreddy?

FYI: The above schematic is completely wrong in a number of places. Remember: this is exactly the same topology as the Screw Driver but with different parts.

Damon Jonesta · Post by **Damon Jonesta** » 17 Jun 2009, 01:48

If you are referring to the missing 100uF on the supply and the reverse orientations of some of the pots, that will be fixed later after i have had a chance to put it on my protoboard and test it out. Some of your labeling doesn't correlate with actual components used and the lug numbering on the pots doesn't match with what is there either. Just plain wrong. My reversal is only as good at best as the "wrongness" of the board.

You traced it completely wrong. Sorry if that sounds like an insult or something. Not my fault you didn't trace it right.

Damon Jonesta · Post by **Damon Jonesta** » 17 Jun 2009, 02:45

Not insulted at all.

I've re-traced it 3 times and basically got the same thing except for the 100uF at the supply and some orientation issues. Maybe it is wrong...

We'll just have to see if it's completely wrong like you said, in which case it will sound like a POS, or if it works. If it's wrong then it's the trace, but you can't denied the lug labels on your PCB is in error. Just saying.

If Mr. Skreddy says there are major errors, then it is so. I'm not taking sides here, but history has shown him to be an honest, forthcoming guy. Your effort is still appreciated, however.

And I don't think he said "completely wrong", for the record.

Skreddy · Post by **Skreddy** » 17 Jun 2009, 04:16

I won't drag this out; here's the schemo.

C15 and C16 are just alternative capacitor footprints.

Sorry; my bad. A couple of drinks and I lose all sensibility.

It's just drawn differently, but your schemo looks like everything connects to everything else in the right way.

are you serious? Did you get your beard all messy.
Any way, C15 is missing from your PCB.
And so is C16... not on the board at all... Did ebay sell me a defective copy?

I only saw 2-3 differences. Not exactly "completely".
seriously check your lug numbering. It's all backwards.

Thanks for the schemo. You are an example for us all

NVM about the c15, c16. Jut saw your post.
You should use my schemo. It looks better

Drinkin' on a Wednesday... I knew there was a reason beyond pedals I love this guy! Thanks for the schemo too. So what are ya drinkin'? I've cut back lately and I've really been craving Guiness and other fine stouts. Wolavers Cream Stout... yuuummmm

Have you met yourself? Seriously the guy gives you his official schematic after saying you have errors on your tracing attempt and you still talk shit.
