This is a link to a thread that someone else had started where I had posted a comment to a similar situation with regard to this radio -- I still have not been able to either identify the model or find a schematic.
The only clue to the tube is a hadwitten list on the bottom of the radio -- I have all the others but not the 55B2
Thanks for the article but what I don't know is enough info about what the tap does and what it's drop should be --
I asked if the 55A2 was a legitimate sup and I got this from Jim at Vacuum Tubes Inc :
Unfortunately they do not sub for each other. It appears the difference is in how much ballasting action is applied to the dial lamp(s)
The "standard" number for the 55B2 is KY55C.
The Amperite universal replacement is a type 50AB. It looks like Playthings of the Past in Cleveland, OH has a few of the 50AB's. Their website is: www.oldradioparts.com
Is there any reason to assume this is not correct ? If all is well with this at least I have a couple more options now.
