I'd like this finished project to go to someone who'd appreciate it. I'm only hoping to get my costs out of it: $800 plus shipping. Full ad is here: 300B Amplifier Tubelab SE Design w "PowerDrive" Single Owner Builder EX Cond | eBay
BUT I'd just assume it be sold through this channel.
The Tubelab SE is not such an easy project when you go off the reservation. I fought to get it into shape where one can adjust the bias and B+ voltage separately, requiring a separate PSU for the B+ (see image below). I also fought to get all the original parts from the BOM including the rare Toshiba MOSFET for the PowerDrive and the proper voltage regulator. I guarantee it to be a fine working example of this very good design. I have tuned it up to My ear but there is plenty of room for the next guy to apply his own criteria!
