HI, It looks good, but seems expensive, given that it's using 6bm8 tubes in push-pull mode. This is similar to the $150 antique sound labs or SE electronics kit that I built a while ago, that uses 11bm8s in push pull. Th estoetkit that Wayne Parham built cost $550 in kit mode, and used 6bm8 tubes also. I think the big difference here is the use of tube rectification with a PI filter, and maybe better output trannies. Not having heard it versus the stoetkit, i can;t say. But the price seems a little high. Th esound may be great, I would love to hear it. Just my thoughts -akhilesh
