hi list!

i found in the junk an curious old device. it says " arc lamps 
starter". it is very old, i think 40 or 50 years old .
i took it and open it. inside i found a little nice tesla coil.

It is a real spinterometric tesla coil, the strange is the secondary 
coil size. the wire diameter is very big than usuall, almost 1 
millimeter diameter. this machine is able to produce arc between 
grounded object and the upper terminal of about 5 cm. But not free 
sparks in the air So i changed the secondary coil with one i did 
before, and it work better, now i can see a small corona. which is 
the rules for building a secondary? bigger is better? i mean , i 
would emprove this machine, so how?

thanks!
