Update and final outcome.
I ended up trading the Kemper for a Mesa Boogie TC50 head.
Very happy 3 channels and it can use 3 different tubes, EL34, 6l6GC and 6V6.
Currently have 6v6 in it, wow sounds great so far.
I must be a muscle car guy, that needs the roar of a V8.
Thanks for everyones help, a long the way.
Maybe back one day.
Cheers.
