notice the lead breakout,
the pri runs underneath the heavy sec, not the best way to wire,
it is better to drill holes in the bobbin or use a bobbin with slots,
this method runs the thin pri wire by the heavy speaker winding,
and this unit was wired out of phase just like the Vibro Champ output i took apart from the same company,
brn goes to the top 6V6, there is a 2.2 k feedback from the sec,
so this will feed back if wired normally, maybe i should give Antique a ring?
so things we can improve on:
dcr is 300 ohms,
the KT88 output i just made is much bigger but has a pri dcr of 60 ohms,
lower dcr and you lower distortion,
insulation is bare minimal, we can use nomex in between pri/sec/pri,
use a 1 inch stack-this means less turns for the same henries,
less turns means lower dcr, and we have room for bigger wire which means even lower dcr, however, our MTL(mean turn length) will go up 20 percent.
lay the wire flat, this will make the xfmr more reliable which means no costly court battles, and we can use bigger wire again, since the turns per inch will go up.
leakage C might go up due to closer wires, but we are using less turns so it should cancel this out.
use 7 sections, 4P and 3S, for better balance and less leakage,
hook up the black lead to the finish, not the start!
use some Ni lams to add perm and thus henries at the expense of a more saturated sound, oh darn,
