AO-35 Coversion (first time)

[rockinmac]

I am a first timer converting a AO-35. I would love to keep it simple with one tone knob maybe a treble roll off and would love to run the first two triodes in parallel(like a matchless spitfire) if possible if not what would be the simplest way of getting a good sound then i can experiment more I also have a ao-39 i wish to convert after the 35. THanks!
