Murphy A46 Part 4 Valve Tube Radio 1939, Mica caps (4K)

Well I'd almost forgot about it except I see it every morning looking at me. Its been over 2 years since I looked at it. I decided to investigate those white mica capacitors and see if they have problems after comments from my viewers. Further strange results in this video make interesting thoughts on what is going on with the tuned circuits. I will continue to investigate. Please comment with any thoughts. Warning:- Valve Tube radios contain high voltages that are dangerous to work with.
