Stu ,
I was just thinking: maybe the problem is comming from your balancer.

Along those lines, Chadwick-Helmuth makes (or used to make) a calibrator
for the purpose of check the balancing equipment. It was a fairly
simple device and probably could be duplicated (as the Chadwick version
was pricey). After chasing the T/R balance on my 269, it turned out the
problem was indeed the CH balancer. It was not an obvous problem.

I looked online and noticed that CH had been purchased by Honeywell and
I wasn't able to find any further info.
