Henry,
Someone's already sent you the link so this may be moot but there were about 1/2 dozen various "dot" cap coding schemes depending on use, industry, military, etc. Usually it's easy to figure out which one you're working with but sometimes one of the colors fades or white turns yellow or red turns brown, etc. and it throws you off. In general they were, as noted, just simple waxed paper caps and now leaky as hell in a particular case style (also easy to "gut" and insert a modern cap within) - the mica ones usually had "mica" melted into the plastic case somewhere (and their own coding system usually). Lastly if it's that early I suspect that you realize it is the old, low frequency, FM band that was given over to a few television channels before the current 88-108 was adopted so even perfectly restored you might not be able to receive anything.

Priceless, the plot thickens
lower frequency how?
Dial has a 88 to 108 scale labeled "megacycles"
Dial also show "channels" 200 to 300
The tuner is dead. It should at least pick up static or atmoshperic pressure. I at least need to get a signal. my gut tells me David Dye will be playing me some great stuff through it soon. Hopefully. Gonna test them tubes now
Thanks for the info
Henry,
Sorry, faulty memory - can't remember perzactly what year the FM band was moved up but you've got the modern one. When I get a chance I'll provide to frequencies of the old band and when it was moved but you're machine was made really close to the time that it was bumped up.

My grandparents had this old late 1940's AM/FM/SW console. It had a wonderful tone. I remember looking at the back and seeing many coke bottle tubes. I remember a 6V6G. And a field coil speaker.
That unit still worked in the late 1980's. They unfortunately sold the unit to someone else before asking me.
Good luck with yours!
