I have now split the two GU81 valves that were in parallel into two separate teslas for the bass clef and treble clef systems and wound the primary coil for the second one. On the left in piccy.
The primary coil formers I use are acrylic flower pots from you know where.

Awaiting more wire to wind another 750 turn secondary...….
.........not looking forward to that !

Have decided that as I have already built (not yet tested ! ) one MIDI converter
kit I would build a second one to serve both of the teslas.

Maybe my EHT will need a boost to drive the two independent systems.
We shall see.
