[Milsurplus] RCA AR60 part 2

[Al Klase]

Hello Paul,

AR60's are rather rare.  I don't think I've ever actually 
seen one. At $495 dollars, not many ham's responded to the 
original QST advertisement.  I've been working on the 
history of RCA short-wave sets in the 1930's and 40's, and 
I'm coming to the conclusion that RCA knew more about high 
performance receivers than anyone else.

If, as you indicate, there was a second version of the AR-60 
using octal tubes, that IS NEWS!  Can you post pictures?

RCA used an output limiter to provide pseudo-AVC for CW use 
in several of their receivers including the RAB and RBB/RBC 
superhets and the RAK/RAL TRF-autodynes.  The AR-60 was 
designed in the time period between the RAB and RBB/RBC.

Regards,
Al
