Title: Cool 1943 US Army training film - Electronic Vacuum Tubes
Post by: Chris H on December 19, 2020, 12:27:05 AM

Not sure if this is the right place to post or of interest but came across this 1943 US Army training film online, thought I'd share.
For a beginner such as myself, I found it clear, concise and every bit as informative as much newer instructional videos.
Gives a good high-level explanation of screen grid and suppressor grid in getting from Triode to Pentode.
