[ARC5] Loctal Tubes

[Dennis DuVall]

My understanding is that Loctals were originally developed for mobile  
use, to stay securely "locked" in their  sockets.  Later on they were  
thought to be superior for RF use  because the pins came straight out  
through the glass on the bottom, i.e., shorter leads and no "lossy"  
bakelite base.  Don't believe the latter claim proved to be true in  
practice.  My direct experience with loctals has been with the BC-659  
FM transceivers where I've found pin corrosion and socket connections  
to be major problems.
