These were built by an experienced amp builder who did an excellent job. They have both balanced and RCA inputs. They include Sovtek 6H30 (not DR) tubes with less than 300 hours and new testing Amperex or Mullard manufacture GZ34 (your choice). I paid $1500, and am asking for $1200 obo.
These kits are no longer being sold. Mine are a very clean and perfectly working pair.
Thanks,
John
