I wired the EHT PSU this weekend. See attached picture. I had to remove the coil from the capacitor can because when it was inside, the oscillator did not oscillate. I think it was because the can acts as a short-circuited turn thus reducing too much the inductance of the coil. I placed it bellow the chassis with two wooden blocks.

But that leads me to another doubt. In radios all coils and RF transformers are inside aluminiun cans. Are not they affected by this? Then, why my reaction coil is affected?
