This Diytube St-70 is a complete remake of the venerable St70. The diytube uses a 12AX7 and 12AU7s for pure triode perfection allowing use of an almost limitless selection of NOS and new tubes. This new driver uses the classic modified Mullard topology with constant current source in the tail of the phase splitter - a perfect mix of performance and warm tube sound. It has low distortion and excellent square wave response.
This unit has about sixty hours of use.
