[R-390] B+ current

I was asked off-line if the 12DF5 is the same height as the 
26Z5.  Apparently, the 12DW4 has clearance issues with the bottom 
cover.  The 12DF5 is the same height as the 12BW4 -- nominally 2-3/8" 
envelope height, 2-5/8" with pins.  (The 26Z5 is nominally 1-15/16" 
envelope height, 2-3/16" with pins.)

BTW, there are a number of good resources on the web for tube 
data.  One of the best is:

Best regards,
