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.

It is a bare driver kit without components meant for experienced tube hobbyists, including:
* FR-4 fiberglass construction that will last a lifetime
* top & bottom silkscreen ensuring easy assembly and friendly modding
* a ruby red solder mask finish that will never make your amp look like a science fair project
* a drop-in replacement with no other changes needed
* detailed schematics & a parts list with Mouser.com part numbers and easy cut-n-paste Mouser BOM
* email support provided and a growing community forum here at diytube.com
* preview the manual (~457k PDF)

Most parts can be purchased easily through Mouser, and vendors are suggested for the others (ie tubes and tube sockets). Go to diytube Poseidon forum for more info and pictures.
