I'm about 90% complete on a rebuild/upgrade of a KT34XA to a KT36XA.
I had to purchase a new balun from m2 because the ferrite core in the
one was shattered into a thousand pieces when I got it on the ground. I have
no idea what caused that? Lightning, banging it when removing the antenna??
But I still had the old balun and there are no markings to indicate +/-,
nor are there any references to +/- in the original assembly manual. There
is also no info on stacking these in the original manual either.
On the new balun (from M2) there is a marking on one of the terminals
looks like an = sign above and below the terminal.
Don't know if this helps or not ...Just more info.

I am in the process of building stacks with various KT 34s and KT 34XAs that
I have acquired and have been rebuilding. I am planning on stacking them
using the Stackmatches by WX0B.
Most of the 4:1 baluns are either not marked with the typical + and -
markings that are usually appear on the KLM baluns. In addition, the one
previously installed KT 34XA is at 65 feet and is inaccessable to check any
Someone told me a while back that in stacking the KLMs it was imperative to
keep the + on the same side for the entire stack. Is this so, and if it is
what is the reason for doing so? I know you can check the balun with the
259 to determine which side is which and plan to do so but does it really
make a difference?
