Driver board designed by Shannon Parks over at DiyTube.com. Engineered as a replacement driver for the Dynaco Mark III & IV as well as your own DIY monoblock, the diytube Poseidon uses a 12AX7 and a 12AU7 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.
