572B Breadboard Linear Amplifier – oh, the insanity!

Today I bring you a video by “bob4analog” on YouTube. His version of a breadboard is slightly different from mine!!!!

Really detailed description of his project and a great tour of it in operation. I have a 572 based amp and found this quite interesting. Others, may just find the layout utter insanity! I really thank him for posting this video, it was interesting and I did indeed learn a few things while watching this video.

From his video description:

An experimental ‘Breadboard’ Linear Amplifier for 80m, using two 572B tubes.
