[Heath] Results of experiment with reactivation of 572Bs in SB-200

[G3OOU at aol.com]

Hi Ken
 
Thanks for your explanatory email on 572Bs made in China. I wondered if the 
 heater current in those is the same as the originals or lower? 
 
This all shows that skimping on the design and manufacture for the sake of  
a dollar or two is a really false economy.
