To get the maximum performace out of the current 6112 tube based MF gear. There are NOS alternatives to the 80's vintage stock Philips tube. The 6112 was designed by Sylvania and I have a 1960's NOS pair in my unit. NOS 6112 may also be found branded Raytheon and General Electric. However, I believe that the OEM on all 6112 tubes is Sylvania. I have also seen NOS 6112 tubes with standard pins (not flying leads) I own a MF A5 cd player and find it quite involving, especially with the NOS tubes. I know of no other player in this price range that performs at a higher level. In the recent past I owned Esoteric DV-50, Marantz SA11-S1, ARC CD3MK2, Krell SACD Standard, CARY 303-300 a loner Wadia 800. The MF is the one that is still here....I must be deaf???
