Hi Njonker Glad you like the Anthem gear. I own the Amp 1 and did have the pre2L. If I'm not mistaken the tube should be a 6922 and it should be a sovtek. I replaced my 6922s with nos philips when I had the pre and valvos in my sonicfrontiers dac. I really like the valvos and the philips tubes don't sound bad.(replaced the pre2L with a ARC) You might try Anthems web site to see what tube upgrade they recommend for your player. Keep in mind you may pay a little more for their replacements. Good listening!
