     I have several tube testers that measure transconductance as well as
inter electrode shorts etc. I've never seen "hardness" listed as a tube
parameter as mentioned. ???? Most of my tube equipment is shortwave
receivers. As far as tube organs go, I'm restoring a 1935 Hammond Novocord.
Ever played with one?
