Good luck with your PL2.
About 18 years ago, I wrote a member review of the PL2.
Without knowing what tubes came with your unit, as well as what the rest of your system is like, and what you like to listen for, it would be hard to give you anything more than some general observations. I do prefer KT 88's & 6550's as the power tubes. I have a PL5 which is still my main amp today.
