Dynaco ST70 DIY tube [Expired]


no longer for sale

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. Features: + Auricap and Ampohm caps + Riken and Takman resistors + Porcelain sockets + Hi-qual German can capacitor + Stainless steel case and hardware + Teflon wire + Shottky diode and mil spec pot in bias circuit + 5-way binding posts Tube complement: + Sovtek rectifier + Tung Sol reissue El34s + Mullard Mil Spec CSV4003 12AU7s + Jan GE 5791 (12AX7) The sound is excellent throughout the audio spectrum, a little softer than my other Diytube st70. I take checks and MOs. Checks must clear befor shipping. Buyer pays shipping.
