  In the Ranger, the LV feed to it's rectifier is from two equidistant taps 
between CT and the 'ends' of the HV secondary, the which ends feed the HV 
rectifier.  I'm a bit worried that if I run the whole radio on the LV 
winding, it will stress it. If anyone has any concrete "real-world" actual 
experience with doing this, I'd love to hear how it worked out.

   Guitar (and other musical) amplifiers traditionally have their volume
knobs marked 0 - 10, thus '10' is 'loudest'.  From whence derives the joke
in Spinal Tap - "This amp was custom made for me - see? the knobs all go
to *11*!!!"
