Retubing ARC sp11: Suggestions?

You need to replace with phono and line stage section.
Highly recommended Siemens 7308/E188cc for the phono section and Siemens 6DJ8/ECC88 for the line stage section.
I've tried just about every 6DJ8/6922/7308 tubes out there on the SP-11 MKII.

Joe and his idiotic pile of lore needs to dragged out in the street & whipped till there is nothing left. I have never seen a bigger pile of misleading info. As if one niwit on a Sunday afternoon with a handfull of tubes tryed on one system is THE judgement on tubes with OVER a half CENTURY of history in Hi - Fi. His off-hand dismisall of all Telefunken tubes should be notice enough that this guy is an isolated & ignorent nitwit!

Fifteen years I had an SP-11 and used original Telefunken 6DJ8s or some Amperex 7308s. Brimar 6DJ8s must be impossible to find now, but were extremely musical and a good choice as well.
