Recently I found another early version of GEWEI (upper) that uses a 4046 PLL instead of the 4013 and varactor junction configuration.
I went through and compared it to the GEWEI that evolved into the Deerhorn.
I believe that Peter went with the other configuration to allow for more gestural and performance capabilities.
The 4046 version only has a single antennae and antennae oscillator.
The 4046’s internal OSC takes place of the feedback oscillator (the other antennae) and the antennae is “tuned” through this IC as well.
The circled section is what the GEWEI/Deerhorn use.
The circled section is instead replaced with this ^
Peter showed this to us many many years ago in the
deerhorn prototype video
And just recently I realized the one on the right was a different version.
I found in the google docs from the timara section of the website.
Here is the first test with one I just built up!

Here is the paper circuit if anyone is feeling adventurous.
Please know, it takes knowledge of this circuit to get these to work, and modifications to the paper circuit as well.
It is not as simple as just building it and powering it up.
I will help when I can, but please know I cannot diagnose everyone’s paper circuits 
Take note of the schem I posted above - as it does show the added varicap (trimmer) and it also shows the lowpass filter that leads to the theta buffer.
Take a look as well at the actual GEWEI and you will see some additional 102 and 103 caps that need to be added in specific spots.
** Edit - Mine sounds slightly different than in Peter’s video.
I disconnected the hardwired FM Modulation that came from the Theta Output.
When Peter originally made these - each only had 1 FM input and 1 single CV output - he would then wire the horns together so they modulated themselves and then the horn next to them (this was the Deerhorn Tapestries - which were made up of GEWEI’s)
However I have not added the attenuveters yet. So I don’t show off any fine tune between the 2 bellows in my vid, but it is very easy to add
Other things that can be done -
^ Note on the AUX.
You can probably get a neat mix on this version of gewei if you add it, however, since there is no switch on this version, you cannot mute the internal synth.
That being said, adding the switch is also very easy!
