I have read that the Fisher 500B was only made in 1961 and 1962 before being replaced by the 500C. And any units purchased after 1962ish were leftover dealer inventory.
These pictures of my 500B indicate otherwise based on date coding information I am going by from posts by larryderouin primarily. I don't doubt Larry at all. I just think the 500B was produced for more than a couple of years as commonly stated.
All of the tubes in this unit were Fisher branded, except for the power tubes, and have date codes of 1965.
(I have replaced some of the Fisher tubes)
Please comment and correct me as needed,
Jef
