Auction is for one (1) tube, balanced sections within 5% of rare PCC189 7ES8 made in EI tube factory in Yugoslavia back in 70s.

These tubes are compatible with ECC88 / 6DJ8 in almost every application and you can often found them relabeled ECC88 / 6DJ8 Philips Holland or Siemens Germany.

They are very, very quiet in RIAA preamps, thanks to the heaters wounded in different way than ECC88.

I have few boxes of 100 pcs PCC189 / 7ES8 made back in 70s in EI Nis tube plant for export. These are premium grade, specially selected and with exceptional quality control for export under Philips, Siemens, Valvo and Telefunken brands. That's why they don't have prints on each tube. 

Geniune IP Philips code for PCC189 / 7ES8 etched on every single tube together with production date and EI tube factory code.

All tubes I have listed for sale are really perfectly balanced with exact or almost exact triode sections due to big qty I have in stock.  

Variable mu triode, perfect for use in tube audio compressors!
