HELP! 20AWP4 CRT Needed for 1954 Magnavox
 

A good friend of mine went through all the hard work of replacing every cap and many resistors in my 1952/3 Magnavox Combination, which my folks bought new when they were married. I watched Captain Kangaroo on it! Now, it works like new (see below!).

BUT, I'd like to return the favor for my restorer by finding him a good 20AWP4 picture tube for a similar 1954 Magnavox that he is restoring. Can anyone help? I would really appreciate any leads.

Best regards,
