Yes, Beware of "late" date-coded 6146W's on the market now. They look
like crap: I had a pair that had the plate caps mounted at about a 10-degree
angle from the top of the glass envelope. One had
a broken vacuum and was all white inside....these were NOS boxed tubes.

6146B's may be the best bet. RF Parts may be a safe-bet and good place to
get tubes.

Hi,

The 6146B tubes are soft in my Kenwood TS520. I need info on a good
domestic USA supplier of tubes. I also need info on the right DMM to
install them.
