Stock input/driver tubes used in Mono 120s: new production JJ with EI Yugoslavia. They sounded okay, a little forward.

Ended up with NOS Mullard drivers and Tungsram or Mullard input tuber in front of the large Tung Sol KT150s for output tubes.

About 150hrs burn in time and it evolved to more of a 3 dimensional sound once broken in.
