the only time stan ever ran more than one tube was when he used the alternator, all VIC's were for one tube set only. even his brother Stephen used 2 alternators for 6 tubes where each tube was driven off of a single phase. I think your 16 tube set would be awesome, but i just wanted to point out the research behind making the decisions, because you can spend a lot of money on a cell, it just depends on what you are trying to replicate and which system you are experimenting with... and the delrin insulated resonant cavities were always small and individually driven, and used over 1000 volts.
