The
analog Phoenix theremin is 10 years old, now revealed to the
public 9.26.18
The
digital people made big claims back then... years later
they delivered R2D2 on a kazoo.
If you want to construct one of the finest original analog theremin designs that rivals and maybe improves upon Clara’s theremin in response and sound then you
are in the right place.
WebPages
unseen till now specifically for the Phoenix theremin project
If
there is any interest there are some areas I would
like to better explain before you build.
There is still room for
your improvements and there is so much more I wish I could tell you but time has taken it toll on my creative theremin enthusiasm, you will be more or less on your own. It is very exhausting
for me as I no longer have the psychic ability to do email troubleshooting.
Post your
interest in my Chat
Forum maybe others can eventually trade ideas.
I use a modular approach to construction on several PCB’s so sections can be easily improved or scraped. The pitch and volume sections are independent of one another.

Mouser Parts
List, one component I can furnish... the Vactrol I use in my PWM volume
control.
Schematic it could be
re-drawn, some corrections on sheet below
Schematic
corrections to the drawing of the audio section above.
PDF pattern to make your own PCB
boards, this is with the latest mods
Top
Silkscreen & Bottom
Copper
I
am making some modifications so check back January
2019
Have
a beautiful classic sound, perfect pitch field
linearity and thermal drift resistance
I
am putting together a Phoenix to be sent to
the great-grandson of Lev Termen himself in
St. Petersburg, Russia for an independent
evaluation. Not until this is completed can I
add
the modifications to the latest PDF
Will
also add a how to make the PCB webpage without
heat and pressure, fascinating!

If you
succeed
building the Phoenix you will have Clara's voice
for a little over $100. You will be compared to or
will be even better
than a finely tuned RCA, yes that Hoffman
instrument. My hope is to be able to share practical information in bite size amounts
from my feeble aging mind as we go forward. When you
listen to what the digital people are doing, something
about the theremin is sadly being lost.
