Yes most of the old links are broken. This post makes it easy!

Chuck and All,

The balancing transformers are nice when more than two variacs are going to
be connected in parallel. However, if you only need to tie two variacs
together, an even easier way is to make a home-brew center-tapped high
current choke. Because the worst-case voltage difference between identical
variacs should be only a few volts or so, it shouldn't take very many turns
of heavy gauge wire wound on an iron or ferrite core to do the trick - say
20 total turns of #4 or $6 AWG, tapped half way through. Most of the flux
in the core ends up being canceled as current is pulled through the center
tap of the choke. The configuration is as follows:

            _____________
 Wiper #1   =============    Wiper #2
      <-----OOOOOOoOOOOOO-------->
                  |
                  |
                  |
                  |------  Out
           
Best regards,

I read the archive thread on the T5587, and the link showing the choke's
construction is broken. Anyone have a copy by chance?
Also, Bert typed up a text schematic of a simple homemade choke for only 2
variacs.  This is a sound idea, right?

Thanks again guys!

Hi all, I have a 3 stack of 1256's that i had recently bought for a very
good price but it is lacking the paralleling chokes.  I was wondering if
there is anyone here that has any T5587 chokes that they are willing to part
with at a decent price.

Thanks,  John
