Dynaco Mark III Stereo Monoblock Tube Amp with Poseidon board. They have DIYTube Poseidon input board with brand new parts.
To be honest there's not much old parts left and they sound great. Some of the best amps I've ever had. But I've moved onto single ended and building my own amps, so I haven't been using them for a while. Will come with new production KT88 Russian tubes, new production rectifier and new production preamp tubes.
