RE: new single 833A VTTC



Original poster: "Steven Ward" <srward16-at-hotmail-dot-com> 

Actually, i just looked at the voltage again just now, it looks like only 
10.3V or so.  Im not terribly worried about tube lifetime anyway.  I ran 
the coil again today for a long time at 15pps.  At 22" the plate is just a 
tad bit colored, at 20, it gets more noticable, and at 30pps its probably 
at about its limit, or at least as far as i would push it.  It makes me 
wonder how people got long sparks before the use of staccato!  It seems 
that the tube would be running incredibly hot really.  Did people just run 
the plates bright red?  Or am i still missing something with my design?
