Description
One (1) tube, PCC189 7ES8 with balanced sections made by Philips Holland in Heerlen tube plant in 60s. This the 1st ever version, with dual stage big ring getter, much better sounding than later small ring getter and A frame types. Genine Philips code is etched on each tube during sealing. There is delta symbol for Heerlen tube factory. They are very, very quiet in RIAA preamps, thanks to the heaters wounded in different way than ECC88. Great tube for audio compressors! These tubes are compatible with ECC88 / 6DJ8 / E88CC / 6922 in almost every application and you can often found them relabeled ECC88 / 6DJ8 Philips Holland or Siemens Germany.
