Al,
Not necessary it would require to have an extra tube for each channel(buffer). Just like in conventional preamp with one main 'out' that can be disconnected from poweramp 'in' I don't see a necessity to have a buffer stage unless you'd like to have both preamp section connected to amp and another set of preamp outputs together.
