I bought one of these amps for a good price from a fellow headfier some time before christmas, and I like it very much with my K340's. Clarity, extension both bass and treble and and transient control/attack is better than the EF2 I used before.
I have rolled in a NOS pair of japanese made EL84's but I'm looking for some other input tubes, I will most likely settle for a pair of 5751 to have a little more movement of the pot, ATM I'm at 8-9 o'clock most of the time, but it will depend upon which deal I can find.
Are there any of the currently produced tubes, that are recommended or should I just settle for NOS tubes?
