I would be very grateful if someone can explain to me why a convensional
coil uses a height to diameter ratio of 3:1 upto 5:1 and most vacuum
tube coils I have seen use very long thin secondaries. I have a 3.5" x
10" secondary powered by three 812AW triods. I get a 4" "brush"
discharge. Will I get better perfprmance if I went  to a secondary say
2" diameter by 36" long.

Regards
Pete
