Another Sylvania Tube Manual Available for download

[Deane McIntyre]

I have scanned the 1950 edition of the Sylvania Radio Tubes
Characteristics book, this is an earlier edition of the one
I posted earlier today. As before, it is available as a 7MB PDF
file at my server:

<http://deane.bio.ucalgary.ca/Sylvania1950.pdf>

The original was a bit rough in places and the scan reflects this
but it should be readable. Some of the tube base figures are a
bit faint in particular but the tables themselves are fine. At
the end is a listing of panel lamps followed by the new fangled
Germanium Crystal Diodes.

73,
