Hi Bob!
You could get a PDF with the specs of the 203A tube on:
http://www.mif.pg.gda.pl/homepages/frank/vs.html
Anyway, the filament specs are 10V / 3.25A
These tubes are very hard to find here in Brazil. Please tell me if you will
not use them! I have some Johnson 4-pin jumbo sockets waiting for tubes!
73!
