[ARC5] [Glowbugs] RAL-7

[Geoff]

Why guess, read the manual.
http://bama.edebris.com/manuals/rca/ral/

BTW it is 600 Ohms.

I have both the RAK and RAL here in memory of having used them aboard a USN 
ship in the early 60's and amazed at the performance. Arguably the best 
regen ever made commercially.
