Hi everyone! I’ve got a rare B.K. Partners A205 amplifier and P205 control unit (circa 1959). The preamp (S/N 237) features an interesting tube lineup: three EF86s and one ECC83, including Phono stage, Tone, Presence, and Rumble controls. I'm currently restoring it and looking for a schematic or shared experiences. Does anyone else own this 'British' pair? I'm curious to know where the other 236 units are hiding! 
Thanks


Thanks
