vttc



Hi there coilers,
    Ok, here's my problem. My VTTC tesla with two 833a's works well. The HV
xmfr for my VTTC has a MOT with the shunts knocked out, running a 1/2 wave
voltage doubler(level shifter). Outputs about 4000 volts with 60 cycle
ripple. I bought a large xmfr with 6800 CT secondary. Using 2 uwave
rectifiers I grt 3500 volts or full-wave. This is 120 cycle ripple. The
sparks are much shorter (but sound much higher in frequency; 60/second vs
120/second). Now here it is. Why when I have so much more power with the
full-wave set up do I get a shorter spark. I have run the coil on 1/2 of the
secondary winding on AC and the sparks are much longer. To me, this is
strange. I would think that more power would give longer sparks. The MOT
xmfr gives 18 in. sparks, big xmfr gives 13 in. on AC, 10 in. on full-wave.
The full-wave is very flame like, very hot. Questions, answers?
