Amplifier Tube Specs for multi-class operation
« on: July 05, 2003, 01:31:51 AM »
I miss the tube spec section of the ARRL Handbook.  I need to know typ/max volts/mils for plate, screen, control for the Amperex 8905 and 6907 dual tetrodes.  The tables in the back of the Handbook were great, but now I can't find any such information for these tubes.  Can anyone one the forum suggest where I might get the information I need to convert some power amplifiers to multimode units??

Thanks

Hi John,
    I'm afraid those tubes were never (?) listed in the ARRL Handbook.  I checked 1971, 1978, 1988 Handbooks and they were not listed.  Do they have any other disignation?  BTW, What's a tube?  (LOL!)

 [ I still have a bunck of 'em packed away!]
