C6J: Xenon thyratron, Peak Reverse Voltage of 1250 volts, Peak Forward Voltage of 1000 volts, anode peak current of 80,000 amps, Ave. anode current of 6.4 Amps. It uses a 2.5V, 21 Amp filament.

DCG5/5000GB: mercury vapor rectifier, rated at 6 amps at 10 kV (60 degrees C), with a 5 volt, 7 amp filament.

ZY1000: is similar to the above mercury vapor rectifier, but has a slightly higher PIV rating. It is also found at the site above (in Spanish): http://ourworld.compuserve.com/homepages/jlvillabona/w-hoja12.htm

NL760L, NL-710L/7509A: similar to the C6J above, except that it uses mercury vapor, is rated for 77,000 peak amps, at 1500 PIV and PFV, with a 2.5V, 21 Amp filament.

BK448/5551A: Ignitron, size B (2 3/4" diameter, 9" long), 500 PIV, 56 Amp continuous, water cooled ignitron. Some info available on the Richardson site and some (for the older 5551) in Tube Lore.
