2x 6N6P or ECC99 each channel, PPP

Edcor's are not expencive
Shown alu box is very affordable too
LL line trafos are not, unfortunately

I might give it a try

I might give this one a second chance :clown:

and... at the time i didn't know about the Blumlein Garter cross reference bias scheme
might make sense to use it for this

how many ECC99 or 6N6P will I need to us a 1K6 PP output trafo ?
my first guess is 6x ECC99 per mono amp
being double tubes means 6 tubes in paralel, in reality
