 6n23p Reflector MATCHED PAIR new -2 pcs 1975 year RARE!                                          NOS HOLY GRAIL 


                                                                               Getter on the wire. For better sound.

                                                                                        TESTED. USSR 

                                                100% ORIGINAL

 *..This is what  says about the  ’75 Reflektor  (Single Wire Getter Post) Silver Shield :
The ’75 SWGP Silvers  were the best. What did they do different? They could discern the most subtile vocal overlays, no matter how complex. Now on these tracks that’s a trip, as at times there are 4 vocal harmonies going on at once. Wow! The HD800s are very transparent, so it’s all presented in 3D fashion, the vocals layered at different depths in the sound field! The bass was deep and well defined, with excellent timbre. Tonally perfect mid-range, Welch’s voice natural, no hint of etch*

Selection of radio tubes. Why do you need to do this?

The selection of lamps is necessary for the correct and high-quality operation of the amplifier. The lamp is set to conditions identical to the amplifier. The sameness at maximum modes is checked at high voltages and currents. When choosing new lamps from a factory batch, for example, you can detect a deviation in the characteristics of the factory specifications for the anode current, and if you do not select the radio tubes in pairs, quartets, etc., this can lead not only to poor operation of the amplifier with high distortions, background , but also its failure. And even if several new lamps are from the same batch, this is not a complete guarantee of success.

The currents of the first and second anodes with: 
Ua=90V
Uh=6.3V

Anode currents with bias voltage minus 0.5 V
Parameter measurement and steepness characterization were carried out in  MAY 2023. 
MEASUREMENT RESULTS ARE SUSTAINABLE AND STABLE!

Dear Customer. I draw your attention to the fact that these unique and remarkable 6n23p reflector lamps of 1975 are a vintage product. Therefore, it is very important for us to carry out a thorough and high-quality training of lamps in different passport modes before selling, which requires a lot of time and constant monitoring of the process. It is our specialists who with the help of highly stable voltage sources and multi-turn variable resistors stabilize the anode currents, and the measurement parameters become stable. Restores cathode emission and improves vacuum. These are complex methods that can take about 4 hours per lamp. But only after such a workout the lamp is reliable, it opens and sounds beautiful. Be sure the result is worth it. We do it for you.
 Buy a quality and prepared product. 
Have a nice and enjoyable shopping!
