Anyone have a schematic of the solid tube? or know the transformer ratio? I can trace it but I thought I would ask. I bought one on closeout today. Stock out of the box did not sound that great. I pulled the foam inside the grill and replaced the 12ax7 with a GE 6072A, that helped alot. The stock output level makes me think the transformer might be about 10:1 or 4:1 if they use a CF. If I change any other parts I will take pictures. 12ax7 in a microphone does not make sense to me. I am also suprised in how cheap the power supply case looks and feels as well as the plastic frame the insides are mounted to. The list price is about $1,300.00.
