After  years of research I am proud to finally offer the holy grail of D Style amps the one and only Steel String Singer! This is the original circuit not a circuit that “kind of gets you in the ball park”. This was known as the SSS#005.
This has the Cathode follower driver tube like the original and the High Low Step filters.

This was owned by Carlo Santana and Eric Johnson.
The amp is also available with the FET input.
Comes in 20 watts, 50 watts, 100 watts and 150 watts.
Available as a Head, 1×12 combo or 1×15 combo.
