Congrsts! You are going to love it.
definitely a made by mullsrd off label gz34 rectifier f32. the stock sovtek sounds dull by comparison and blew out in mine after 3 months taking fuses with it.
i have tried lots of 6SN7 and the EH are easily improved. The 50s Slyvania GTA sound excellent, are reasonably priced and NOS are in good supply.
