hello coilers,

I want to replace the antenna in my pll (class-e) system for a ct on the base of the secondary (see schematic), what do I have to change to do this?
I was thinking of a couple of 5 volt zener and shottky's like steve ward do this in his drsstc.

the reason is that I wan't to place a second coil for stereo sound, so I can't use a antenna anymore.

q2 can I use amidon t50-2 for the job?

fres is about 4.7 mhz

I have seen twin coils ran on an antenna before. They say that the antenna just has to be a lot closser to one of the coils.
