[HBR] 50Khz IF Transformer fior new Build

[Steve]

I am in the process of gathering parts and I have been dealing with trying
to find IF Transformers.   I have quite a few 265Khz ones that will need
modifications, 5 ea  85Khz ones from an ARC 5  and some 50Khz ones from a
junker National NC300.  So the big question for me is which sets should I
use?  Modifications of the 265 is quite a task, so it seems to come down to
using the 85Khz ones whihc there is plenty written about how to do that or
use the 50Khz ones from the National.  Any reason that I should not use the
50 Khz ones, understanding that I have to make a few changes in the
oscillator frequencies...The 50 Khz ones would be easy to use and mount on
the chassis.  This the last major hurdle for parts that I have.
