Anyone know the advantage of using a 7543 over a 6AU6A in the VFO of a
KWM-2.
I know both will work and that the 7543 has low hum feature.
I can't tell any difference with one over the other when
I exchange the one in the VFO of my KWM-2.
I am sure the answer is in the CCA archives but they are down again.
Thanks in advance,
