Mr. Mark Keppinger has informed me that his all solid state design/development work is nearly complete, and his given me permission to foward this information. More details to follow soon, but the design is not a FET adaptation of his renowned tube model, but a completely different approach, similar to a Big Briar Model 91 in some ways. Philip Neidlinger
