[Milsurplus] LV on ARC RX

[Charlie L.]

I have run every ARC 5 receiver I have on only 28VDC B+.  Have to use a set
of headphones, but with a clean DC supply, feeding 28 to both filament and
normal dynamotor B+ pin, they work fine.  The ARN6 RDF uses all common
tubes and runs only 28 on the plates.  I have never analized the ARC 5 on
28V B+, checking sensitivity and selectivity, but just for normal
comparisons, seemingly  very little difference except for audio power out..
