SUPER PRICE !!! 6n23p REFLECTOR-SARATOV new lot 100 pcs. + Bonus 3pcs. - (1966-1989 YEARS)

                                                          For better sound.

I present to you a lot of 100 pieces of the new 6n23p Saratov factory with a silver AND gray shield. On some lamps, the inscriptions are not visible, due to long-term storage. You can always request additional photos. Have a nice shopping !!!
A TEST WAS MADE RANDOMLY FOR A HALF OF A LOT. GOOD RESULTS. 6N23P TESTED WITH THE EQUIPMENT:
1. Powerful stabilized power source UIP-2.
2. The stabilized power supply B5-7.
3. Voltammeter M2018 for measuring the glow current (error +/- 0.2%) ./- 0.5%)
4. Voltammeter M2020 for measuring the anode current (error +/- 0.2%).
5. Digital multimeter for measuring incandescent voltage (error +/- 0.5%).
6. Digital voltmeter V7-22A for measuring the anode voltage
7. UK-830LN digital multimeter for measuring bias voltage (accuracy +/- 0.5%).

NOTE:
6n23p are checked for operability, but without fixing the measurement parameters for each lamp. This service is not included in the price of this lot.
