Has anyone built this phono stage you can buy on ebay as a circuit board.

I bought it for 23 dollars and it's actually a nice phono stage based on the Sansui but with an SRPP and more tubes. It uses a pair of 12AX7s and a single 12AU7,three tubes per channel. Here is the schematic but with a low output MC cart you don't need a stepup device..Here is a schematic. I still have more switches to install of course. Then I have a 280v supply all ready for it.
