[Amps] 4CX600A

[kg7hf at comcast.net]

Interesting!  The pair looks just like the 'B' and 'F' versions (gold, round top), they say Eimac, and made in the USA, but that is really all that is on them.  That sure supports why I can't find a data sheet.   Another amps reader Rob sent me this document in the link below, it has mention of the 4cx600A in a table, and gives various specificifications.   They came second...thrid...fourth hand to me so I don't have any idea where or what they are used for.  I guess  I can figure out the pin out, but before I embark on the project, it would be nice to have more detials on what the heck I have ;)

I have a 24 page Eimac brochure on the 4CX600 family of tetrodes. In the brochure they state that the initial members of this family is the 4CX600B and 4CX600J. There is no mention of a 4CX600A at all.

This makes me wonder if you might have an Americanized version of a Russian tube in the GSxx or GUxx series.

Anyone have a data sheet for the 4CX600A?  I've found 'B', 'F', 'J', and 'JA', but not an 'A'.   I would like to know if I could use a pair of these in a 144 Mhz amp.  Also the real data sheet would be handy ;)
