Platinum matched pair PCC189 7ES8 Mullard very quiet ECC88 6DJ8 6922 sub

Two tubes (2 pcs), platinum-matched pair within 5% of the rare PCC189 7ES8, Mullard.

These tubes are incredibly quiet in RIAA preamps, thanks to the unique heater winding method, which differs from that of the ECC88.

They are fully compatible with ECC88 / 6DJ8 / E88CC / 6922 in nearly all applications and are often found relabeled as ECC88 / 6DJ8 by Philips Holland or Siemens Germany.

All pairs we have listed for sale are perfectly matched, with near-identical readings across all four triode sections, thanks to the large quantity we have in stock.

Each pair has been tested on a calibrated Tesla BM215M tester for plate current, and they have been checked for hum and noise in a preamplifier.
