[Amps] 6146B vs 6146W

[Steven Grant, W4IIV]

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

if you choose to run the "W" (a rugged version of the 6146A) it should work ok tho cause those tubes were much more stable...of course settings may be a tad different

I have been reading up on the 6146 and would like to know if the "W" version would be suitable for use in a TS-830S. I have read that the "W" version is rated for less plate dissipation -- is this because it is a ruggedized version and the ratings are "conservative," or does the "W" truly have less plate dissipation than the "B" version.

Thanks in advance...
