Reducing some of my 6922 tube stock. Unused except for testing (by TC Tubes) and come with recent test results. Low noise rated for phono stage use. Original boxes.Here's what the Brent Jesses website has to say: " Fabulous original 1960s vintage white label HOLLAND made Special Quality (SQ) or Premium Quality (PQ) type tubes. Ultra low noise, matched triode sections, heavily plated gold pins. Carefully matched to within 2 percent. These have been rated by audiophiles as as good if not better than the famous Amperex, and rivalling the famed Amperex 7308 white label tubes! Most are Philips SQ or Amperex PQ labels. Some are labelled for Mullard, Philips, Dario, RTC, Valvo or other brands, but all have the Philips Heerlen Holland factory code. " I will include PP and shipping to lower 48 states at asking price.
