You can't unless you find them used. They were actually made from the Dynaco designed circuits after Dynaco's demise.
A company bought the designs ungraded the components to a degree and started producing Sound Valves amps.
You can find them occassionally here or on eB*y. They are easy to mod and if you like the Dynaco sound can be a real find.
