This is a VTA ST70 preamp board fully assembled
Only needs 1 LM334 which I misplaced during assembly.
This is a huge upgrade to the Dynaco ST70 Amplifiers
use 3 12au7 tubes as well as 12bh7 this is an extra board
I built for the Bob Latino ST70 it has never been used.
Was built using all Cardas Quad Solder you only need
To add the 4x .22uf input caps.
$75 shipped
