Tau DHT Amplifier – first build.

After completion of the breadboard stage the questions were laid to rest. After more than a year exploring the circuit variations which tugged on the curiosity the circuit wound up back at the original design with parts section as anticipated. I should add here that the “natural motion” of an interstage or output transformers spoken of in vintage tube building lexicons that does indeed sound more natural than any of the other topologies such as, Ultra Path, Parafeed, plate chokes, plate resistors, plate CCS etc… The AC activity moving in both directions simultaneously within the transformer might have something to do with it. This speaks directly to the hierarchy of circuit over layout, layout over parts.
