5 x Philips PCC189 / 7ES8 (equivalente a ECC88) - NOS
I am selling a set of 5 Philips PCC189 / 7ES8 tubes, equivalent to ECC88.
All tubes are NOS, manufactured between 1961 and 1964 at the Philips Heerlen factory in the Netherlands.
Features:
• All have internal A-frame and disk getter structure
• Filament voltage: 7.6 V
• Tested on professional AVO CT160 equipment
Measurement results Ia (mA):
• 15.9 / 16.5
• 17.5 / 19.8
• 17.5 / 19.2
• 16.4 / 16.6
• 17.9 / 17.0
All values ​​are listed on the box labels. The AVO specification for these tubes is 15.0 mA – so all tubes are excellent, with very good and balanced values.
Extremely rare tubes from this period of manufacture, ideal for audiophiles looking for warm, detailed and authentic Philips sound.
