Latest thoughts.
Delving into SSTC's I have decided to make two small ones for treble and bass clefs.
To save time have bought 2 secondary coils from USA. A chap there winds all sizes to order and is reasonably priced.
Now this bit might not work.…….The 2 GU81's will be reconnected as one system as before and will be modulated with the
bass clef
divided by two (one octave lower) !
So the valves, will hopefully, be playing very low whilst the two SSTCs each play the normal polyphonic music.
This will not require any more MIDI converters.
So I am now teaching myself about winding my GDT's (gate drive transformers) and the rest of SSTC circuitry, which is all new to me.
It should, I hope, sound good...…..living in hopes.
