Tesla Coil Questions (MOT Stack, Rotary, etc)

Original poster: "A" <striker754@xxxxxxxxxxxxx>

I need some help with some tesla coil stuff guys!

My tesla coil had been working for some time until one day one of the bleed resistors on my MMC caps blew out and arced to the capacitor. I'm not sure if the cap is shot or just the resistor died. I haven't messed with it until now, so I have kinda forgotten how to fix everything! Been too busy! It gave some pretty decent arcs before it blew up, it was pretty cool!

What is the resonance cap and the LTR cap? I've been out of this too long!!

Here are the pictures of it: www.theflyingbullet.com/teslacoil/

The specs are:


9000 V 60 mA NST
Couple inductors in series I got from Terry Fritz to protect the NST
~15-16 turns depending where measured

24 AWG wire
6" diameter
coil is 30.5" tall

Toroid is a donut shape. Piece of wood inside a dryer hose covered in aluminum

My MMC caps are 2000VDC and .15 uF. I have a string of 6 in series and a string
of 5 in series. I can get more but Hopefully these can work.

I would like to get this back running, not sure what I should use for the caps.
I see LTR and resonance and not sure which to use!

Also, for spark gap, I'm using a crude setup with a couple copper pipes.
www.theflyingbullet.com/teslacoil/124_2443.JPG You can see it, its the white plastic tee with duck tape on it. I put a leafblower in that ducktape to blow the spark out. Its not a very precise setup as it can move alot and is a PAIN and would like to move to a rotary setup. I also have a 4 stack MOT in oil that I would like to power the new setup with. It provides some pretty heavy duty power. IIRC, it draws around 80 amps at 120V when shorted. Makes one hell of an arc too! What specs would you need on that to know what capacitors to use for that? I really want to get the MOT stack running to get some better arcs out of this coil.

I also have some extra MOTs and microwave caps and magnetrons for sale if anyone needs them

Thanks a bunch, I appreciate the help!
