[Hammarlund] HX-50 vs 50A manual

[John E.]

Looking for information on the differences in the operators manual 
between a HX-50 and a HX-50A.

Thought I read some where it was just a supplement in the HX-50 for the
HX-50A manual.

Looking for that supplement or a manual for a 50A.

Thanks de John K�CQW
