2x Telefunken-branded PCC189 (7ES8 ~ECC189 ~PCC88) Siemens Codes, NOS/NIB/100%+!

For sale are two pieces of Telefunken-branded, Siemens-made PCC189 tubes in NOS/NIB/MINT condition. These are a vari-mu variant of the PCC88, and are nowadays used e.g. in high-end audio limiters or audio preamplifiers. These have identical factory codes: IP3 ≠3H and identical batch numbers 50131! Tested as 100%+ and with well balanced sections at: Tube 1: Ia1= 21.00 mA / Ia2= 23.60 mA, S/gm1= 12.20 mA / S/gm2= 13.70 mA Tube 2: Ia1= 18.90 mA / Ia2= 22.50 mA, S/gm1= 11.50 mA / S/gm2= 12.70 mA Where 100% at this working point is approx. 15-18 mA and approx. 10-11 mA/V. They were also screened for shorts/leaks (hot/cold), and found to be great performers in all tests. They were left on a tester for a prolonged period to ensure stable performance. Tubes come with a meaurement sticker showing tested values. I have more vintage tubes for sale in my other listings.
