Hi Mike
Siemens RS1026 has the Eimac 5867A as an equivalent.
>From the Eimac catalogue:
"The 5867A is intended for use in industrial heating applications. The large
heat storage capacity of the graphite anode aids in compensating for the
wide variations in load generally associated with this type of service.
The 5867A is also suitable for use as a RF or AF power amplifier."
Some tube data:
Plate diss: 350W
Grid diss: 30W
Max Fq: 50MHz (for max ratings CW)
Amplification factor: 25
Filament: thoriated tungsten, 5V at 14.5A
Max ratings: plate 4kV at 400mA
If you don't have the Eimac catalogue I can dig out some more specs for you.
