About the multispool VIC in my opinion the thing that matters is that you have few turns and a low L value of each spool to increase the resonance frequency and still have a huge series resistance . Otherwise it is impossible to hit resonance at a high enough frequency and not get alot of Amps into the cell. His old one is simpler and there is no reason the multispool VIC should not work with the EEC. Remember Stan had only limited time to document what he was doing.
