I got my Quicksilvers back today, listening to Diet ILg presently old friend.
Jeff said the problem was that the old style way to bias the tubes in these with the LEDs had failed. He added some multimeter plugs to set the bias. All sounding great and for those using PSAudio, I went back to Windom today.
All told, the bill came to barely $200.
Happy Camper.
Thanks all,
TD
