Not a bad idea but no, it's a new amp/preamp design to celebrate the SRA-6S, the first high end Stax amp. I'm working on a prototype with tubes you've never seen before and are very cheap in a circuit similar to a mini WES or a balanced HEV90. Nothing is set in stone yet but the plan is to have the PCB's available and if I can get somebody locally to make me a chassis, build a few amps including one that I'd send as a gift to Stax.
The main problem I have is the tubes are very hard to work with (i.e. I need to compile some of the data myself) and I really need a clone to get all these projects done.
