Replace CJ with new equipment

If you like what you're hearing, I would also say get it refurbed. Older CJs have a very specific sound that few others can reproduce. As long as you are doing it be thorough .

I would like to add that CJ and Klipsch make a great combination.   I have some La Scalas and always wanted a PV 10 to match up with a small McIntosh I own.

@Komander  not to start a thread jack but Yes as  a general rule NOS tubes are much better but there are some really good modern tubes around these days.   I have a very large collection of NOS and ANOS tubes so ……..

The older CJ gear isn't full of haze per se. It was a a warmth treasured by some .  Modern clarity in tube and SS gear became respected only later.
