The 6146W has a ruggedized filament. The rest of the characteristics may
be the same as a 6146A or a 6146B depending on when the 6146W was built.
From what I have gathered the early 6146W was the same as the 6146A but
with rugged filament. After the 6146B came into existence, a short time
after that all 6146W's were made the same as the 6146B but with the
rugged filament. So if the 6146W's you have are later versions then they are probably the same as the B. As far as a B not working in place of a regular or A version, I have never had a problem with interchanging them except in the collins radios where you sometimes had to change the neutralizing circuit to get them properly neutralized. In VHF and UHF radios it may be more of a problem. In your HF rig, plug them in and if you can neutralize the final they should work fine. 73 Gary K4FMX Steven Grant, W4IIV wrote: you may run the "W" if you wish the 6146B had different capacitances from the 6146, and 6146A, so the B would not work properly in older (and some newer) equiptment. it caused bad parasitics.....in my opinion, this tube (the "B") should not have been called a 6146 at all...it is that different
