I went through lots of anguish with the first version. Now we are doing V2 with two chassis. Jeffery Jackson breezed through town and gave me some pointers including perhaps using 71A. It turns out most of the 12A tubes I had were extremely microphonic but we found a quiet pair. I wish I had labeled them 12a isntead of 112a lol… Oh well. I’d like to get this one off the bench by Christmas and into the rack. I’ve only started the top plates.
