Again, Chip remembers an earlier post of mine. Align all high voltage
leads and knobs so they are "purdy" and straight! Cross over and rat's
nest accordingly, to bring all in phase, all low voltage primary leads.
Do this transformer by transformer (see my earlier post) never with an
It appears that every day is a new day in the Neon sign Xfrmer business
and the primary/secondary phasing is never done the same way twice in the
Finally, it is always only necessary to change only one side of any
trnasformer to bring it in phase. Always fart around with the low
voltage side only!!
