Greetings to all the brilliant people of this forum. I've been reading through it for a while and have arrived at some questions, which I feel I am ready to ask.Some background first. A little while ago I set out to build a Theremin. After somewhat extensive research and some minor experiments I arrived at the understanding that a handmade Etherwave would be optimal for me in terms of its capabilities, expenses and personal involvement. So what I have now is a EW schematic from respective Hotrodding manual and couple Thierry's posts dating back to 2009 which mention improvements made by Moog on the part of linearization coils (3 coils in H-formation instead of 4 coils in a zig-zag pattern, reducing their mutual induction), and the Hotrodding manual predates these improvements, so they are not included in the schematic.What I want to know now:1. Is there any more up-to-date EW schematic available than what's in 2003's Hotrodding Manual?2. I am considering a different power supply scheme. Everything to the left…
