No. They are ruggedized versions of 6146A's. Still have the same heater
voltage (6.3) as regular ones. Note that they are NOT the same as 6146B's
however in a TS-820, it may not be noticable.

6146B have 6.3V heater. What tube are you using exactly?

There were several variants with different heater voltages. I once
bought a bunch of them cheaply at a hamfest. If you were building
your own rig and could set the heater voltage, they were well worth
the price.


yes, I remember, but afair they had different "names", surely not
marked as 6146B.

6146W IIRC

Nope. A 6146W is just a ruggedized version of a 6146B. Same pinout,
voltages, everything. I have two of them in my Kenwood TS820S, replacing
S2001s.
