Getting close to being done with these. These enclosures are such a pain in the ass but I love them. If someone made an aluminum version that would be a godsend.
Some details:Transistor Sockets
For the NPN, I have 2N3565s from Small Bear that I will audition vs other NPNs I have laying around. I built my last one with a NOS 2N2222 and had planned to use those for the NPN but going to play around a bit to see how the differences play out. The 3565s' HFE readings are all over the place so really interested to see how much a higher HFE won compares to a lower HFE one, etc...
For the Germanium transistor, I have some NOS Texas Instruments 2N404As but also have a ton of other PNP germs I want to try out as a lot of them sounded great when testing the circuit a few months ago. It's a bit of a rabbit hole doing this but fun...Trim Pots
Added a couple of trims to help dial in or out the octave down. Tested this on by boxed version and works pretty easily. I'll probably mark the trims with a fine point sharpie and set the circuits for the octave down in case anyone wants to fuck with the trims. What's great is that the circuit is pretty forgiving and it's easy play with the trims and it's not too sensitive to where you will lose a perfect setting but fucking with them. I can give some simple instructions for those who end up with these.Diode Clippers
There's an on / off / toggle for 3 options. I was going to just do 2 options but decided that I might as well include an option for no diodes. So center off is no diodes with a huge volume increase. I highly prefer the circuit with diode clipping but easy enough to include. The other options are stock clipping with 1N695 germanium diodes and another for silicon clipping diodes with two different types (914s and big can NOS diodes that I found a handful of at an estate sale). So 3 different sounds, probably fancy the silicon the best...
Aiming to get these done next weekend. 1 or 2 are spoken for right now so there will be 2 available at $175 USD shipped CONUS. Overseas prob add another $10 USD.
