Philips E188CC (ultra premium 6DJ8/7308) SQ Special Quality tube 1963 (VR6∆3I3)

Rare NOS E188CC (ultra premium 6DJ8/7308) Philips SQ Special Quality type, early LARGE HALO getter type with grey sides, made in Holland, gold pins

New Old Stock Original Box. Rare Heerlen, Holland 1960s made 7308 type tubes (Philips plant where Amperex Holland Bugle Boy tubes were made) similar to Telefunken or Siemens Cca but with a bit more midrange warmth. These have the grey sides and the large halo top getter that is most often sought after in this type of tube. These are the Philips SQ white label type. Rated online by some audiophiles as the best audiophile Amperex made 6DJ8 type ever made, at any time, even better than the Cca type. Gold pins, Heerlen Holland factory mark, large halo getters, very low noise. These are VERY scarce in the USA
