6 volt recifier tubes

no gas · 1st September 2010, 03:21 PM

What are some of your favorite 6 volt rectifier tubes? I'm looking for a good high current, highish voltage unit a la 5ar4 in a 6 volt flavor. I have no problem using pairs if need be.

I use pairs of 6AU4GTA in some of my amps, works greats.

6Ц4П

6Ц5С

Any idea what they are in english? My cyrillic(sp?) is lacking this time of year.

6D20P, 6D14P are dampers.

6Z4P and 6Z5S are kenotrones (rectifiers)

Here you go: ''Èñòîê2''. Ðàäèîëàìïû - ïî÷òîé. Ïàðàìåòðû è õàðàêòåðèñòèêè ðàäèîëàìï.

6BY5 (octal) oops...

6CA4 (noval)

6CM3... The daddy of all the American dampers. A pair will output 800ma, BUT they take 2.3-2.5 amps each filament current.
Nice slow warm up time.

Only 6V rectifier's I've used are 6X4 and 6AL5.

None of the diodes mentioned here will deliver the power that a 5AR4 can except for the damper diodes.

The 6BY5 needs a rather small input cap to survive and they will spark out if you use the typical 47uF. The 6X4 is a wimpy 7 pin rectifier, the 6X5 is the same thing in an octal package. The Bendix 5993 is a bit better, but specced at only 70 mA, and blows up at about 140.

That leaves damper tubes. These are designed to run as a pulse rectifier in a TV set. Many have a very high heater to cathode breakdown rating so they can run off of the same heater supply as the other tubes. They come in many flavors and ratings in 7 pin, octal, 9 pin miniature, and 9 or 12 pin compactron. Two tubes are needed for a FW rectifier. Several are on the ESRC dollar menu. Look for type numbers ending in 3 (sometimes 4).

The 6AX5GT is a nice little octal 6 volt rectifier. I don't think anyone has mentioned it yet. Though I think the noval 6CA4 will deliver a little more current...
