HI Earl,
Thank you for your help, appreciate it. I have Sevick's book and have read
thru it several times..I just couldn't figure out if splitting it to 2 cores
changed the winding count. I have pretty much found that I can get a flat
response with my 2" Arnold MPP type cores, 125u from 1Mhz - 45MHz, with 7
turns per half, it just gets hot when running 500W carrier thru it. I don't
know what is "normal" allowable heating...maybe I'll try a stock W2AU to see
how hot it gets under the same conditions, into 50ohms tho of course.
You gave me an idea though, to stack 2 cores instead of splitting into 2. I
don't know which method would be better though...
Thank you
Paul

You can get higher power capability by using a larger core, stacking
multiple cores to make a larger core, or using 2 1:1 baluns on separate
cores in a series parallel combination to make a 4:1 balun.
Sevick's books cover it pretty well. This page talks about it as well:
