Hi All,

I have a pair of 5D21 tubes I want to put into AM service and can't find any specs on this tube. Does anyone have any information on the pinout, voltages and specs for this tube? Any information would be greatly appriciated. *TIA*

Hi Dave!

Try this:  http://www.mif.pg.gda.pl/homepages/frank/sheets/061/p/P535-1E.pdf

It's a complete data sheet on the tube.  This is the best tube data website on the internet,
in my opinion.  Here's the address for the main page: http://www.mif.pg.gda.pl/homepages/frank/

Good luck...by the way, that's an interesting tube.  I'd be interested to hear about your progress with
the rig you are planning, the design, performance, etc.  Please keep in touch (if you have the time
and inclination, that is!).  You can email me at: shaw@swcp.com.

73,
Ken
