And I just wanted to say that golden wire looks very cool =)

I guess you are trying to make a 4-channel audio system..?
Nice BP...

Done number two...


Well congrats... tongue

Maybe you can find some litz wire on ebay if your trifilar winding still overheats? It would give much more surface area compared to just 3 conductors. Though, what you have there looks like it should get you good results.

Can you try to use a breakout point that doesnt explode into a shower of sparks? It would be nice to see the actual discharge, to note any differenced compared to a "low" frequency SSTC.

Fins? WTF, it's a Tesla coil, not a light sabre. wink

Firkragg: Winding a high frequency coil on a tubular former made of low-loss material is hardly a new idea rolleyes I've even seen things like BP's skeleton coil former inside radio transmitters, but made of ceramic.

I don't think the winding is trifilar.

looks like bp ends his coils with 3 half-turns thru the former.

I don't think the winding is trifilar.

I was talking about bp'S 'golden' coils; they are wound using 3 wires together, but all lined up on same form.

It looks very nicce but I still think 'skeleton' coils with large amounts of thinner wires beat it on some level..

The golden coils are single-filar, terminated both ends with half-turns through the former as Electroholic observed.

Why thankyou. Not my intention, but I'm sure it's an admirable quality =P

Just for kicks, I'm going to wind the fourth former with 0.25mm wire to make the frequency a little more manageable and see how it performs.
