[TCML] mini Tesla coil specs

5kV/60 mA sounds good.
Thinner wire on secondary, lot of turns (above 1000)
Lower than resonant primary cap for a high BPS.
Take a look, this is one of my old projects made with a 9.5 kV/23 mA OBIT:
Unfortunately, I burned the OBIT (was no protection with safety gap), so the re-incarnation of the coil was with a smaller OBIT unit (5 kV/15 mA, with half of the shunts left in place for more current). A few pics:
And a little movie with the new setup:
For your unit I would go for a 7.5 cm diameter secondary, D/L = 1/4, 1200 turns with 0.25 mm wire.
