Greg, all-

(“Going up to 8kvac with 4 series MOT's solves so
many problems and makes things more stable and
predictable.”)
You mean the MOT’s with the capacitive ballast correct? I got my hands on 
this big transformer-
Specs: the faceplate on it reads-
Ram transformer corp.  #50    type B-29608-Y
5000va     60 cyc     3 ph 6- 73 date
Primary- blank  secondary-blank
Terminals 1-2-3 430 volts
Terminals 4-5-6 460 volts
Terminals 6-7-8 200 volts
It has 3 windings on an EI core.

Sound like a good ballast for a 4 pack?.... at the very least the core
laminations will work in my slide choke.)-

I was reading that 4 MOT’s and a ballast cause some, um….. “Oddness” in the 
AC phase. This troubles me because I was planning on using a SRSG with my 4 
pack. I am imprested with your MOT work but I couldn’t find any mention of 
a sync gap on your site. Have you used one before?
The SRSG I use with my 2, 12/60’s works like a charm (thanks to the folks 
on the list) and the sparks are slower and longer than my non sync gap 
work. I like very much how the spark looks and I was going to shoot of a 
similar performance with my MOT’s. But if the AC phase is shifting all 
around perhaps an Async gap is best. What do you think?

Read you later
