Tubes in stand-by formation... Interesting idea... Sounds like a good line
to give the FCC when they show up to see the twin 8877 amp in operation!
<<Personally, I don't like cramming all those solid state devices together
that way when 1 tube will do the same.>> Not sure what this has to do with
anything other than failing eye sight.
Transistors surely aren't for everyone...I own tube stuff too! ...but, get
back to me in 5-10 years when all your tubes are gone/ manufacturers are all
out of business and we can discuss this again.
