I thought I'd quickly drop by and post this interesting (I thought so) tidbit I just came across. You may remember that the Red Llama PCB had a bunch of extra space on it that looked like it could be for a Jordon Bosstone style circuit. Well...if you look at this picture, the Purple Platypus PCB is in the top right corner, the Red Llama in the left, and the bottom is a closeup of the values:

The Purple Platypus is a Tube Sound Fuzz/Red Llama mixed with...something.
dum dum dum....
hmmm...what could it be?...
I always thought the Purple Platypus was a Octavia/Octave Face style circuit, but that combination of 4049 + two transistors with clipping diodes doesn't look like anything I've seen before.
I posted something about this a while back when we were discussing the Red Llama.
I had a Red Llama and traced out the whole thing using the values printed on the board for the missing components.
It is a Tube Sound Fuzz into what looks A LOT like a Green Ringer.
There are a couple of offboard connections that I couldn't figure out.
Please post a full pic of the inside and/or any other details like transistor types.
I'll be glad to share what I've found once I have the complete circuit.
Thanks.

Sorry to disappoint you Jason, but the pic is just from someone's eBay auction:

The PCB looks like it's wired up exactly the same way as the Red Llama.
is it that effect that we figured out the DIP is a transistor array?
Nope, that was the Swollen Pickle. The Red Llama is a tweaked Tube Sound Fuzz based on a 4049 hex inverter. You can find the schematic by doing a search on the messageboard.
Is that the UBE or unbuffered chip that can't be found easily?
It's the unbuffered version. I found that out the hard way :oops:

The 4069UBE is easily found at www.smallbearelec.com :D (45 cents)
4069 and 4049UBEs can be found at DSE and Jaycar, too.
