I need a reliable source of tubes to restore several Grundig &
Blaupunkt table radios which are missing several tubes.

I also need a tube diagram or schematic diagram of a Blaupunkt Ballet
model # 20003 table radio (Late 50's - early 60's).

All the common European tubes are available
from a number of online vacuum tube dealers.
Do Yahoo search on "vacuum tubes" and snoop
around. As for the schematic, you might
try Walter Groer at
http://www.geocities.com/Paris/6483/

He doesn't have the specific model number you
requested on his Blaupunkt page, but every
Ballett he does have listed uses the same tube
line-up so I'll bet they're all pretty similar.
Of course the chassis layout can be wildly different
from set to set but they're all 5 tube sets so
shouldn't be too hard to figger out. Sams
Photofact also has a Ballett listed. See if one
of your local libraries carries them.
