Hi Masimong,
As a former owner of the PL2, may I suggest a few tubes options that made this amp sing. I did try the Mullard CV-4004 Ca. 1980's and found them rather boring so to speak. No real advantage over the stock 12AX7.
After speaking with a fellow Agon member who's opinion I trusted on the best tube for this particular amp..I found that the old 1950's RCA/Tung Sol Black plate's used in combination with a pair of Sylvania Labeled CONN 12AU7's also ca. 1950's was by far the most pleasing and life like sound I obtained from the PL2. These tubes gave the music weighty presence in the lower mids and a textural midrange with clean highs. If your interested in looking for them..Give Andy at Vintagetubeservices.com a try.
