I usually see him several times a year. He said he has about a dozen amp designs / ideas. The Deco 36 and this one might be called the Tremovalve. Uses the Univalve power amp. The preamp is a single tube. For maximum touch response.
I think he said he built a preamp. But this would be the first full Tremovalve.
He talks about building some combo amps based on these designs. But I think he is more happy fixing amps than production.
