I just put all new pre tubes in '06 Herbert. I put Ruby 12ax7ac5hg's in v3-6 and hg+'s in v1 and 2.
The tubes I took out were a Tung sol 12ax7 in v1 and a tad 325(b) in v2. the rest were ruby 12ax7a in v3-6
Any chance these were the original tubes. If not anyone know why the tad325 might be used in V2?
