The Reflector Corp based in Saratov in Russia made some of the best Russian military types.
All items are original Military sourced items and therefore offer superb build and sound quality.
The 6P14P is the original Reflector made 8000 hour super EL84 that was originally designed for the Russian military.
This valve has special design parameters and because of these you will not find a valve that will provide better performance.
The Features:
These valves were made with the highest grade components and precision and were all tested using the
This involved reducing the filament voltage with the result monitored at every stage for a drop in
transconductance for a designated time period.
As a valve is used and gets older the ability of cathode to emit electrons decreases.
So valves with no drop or only a small change in transconductance would get the 10,000 rating.
The second part of the test was measurement of residual reverse current.
Valves that met the highest standard were rated at 10 000 and given 6P14P-EV marking.
The other feature of the 6P14P-EV is that they were designed to be resilient to vibration so great news for guitar amplifier users.
This valve was very expensive when they were made and was never available for commercial use.
This valve is extremely rare!
The final important points on this valve, of which there are many is that it has a wider bandwidth and has
20 % better transients
when compared to the Philips or Mullard EL84.
The Russian specification sheets show the heater tolerance is around 10%.
So for an EL84 output pentode this is really very special.
The valve also has 14 watt plate dissipation, higher than any European made Mullard or Philips EL84.
It is not surprising that this valve sound is very clear, open and sweet.
The valves transparency and dynamic response is superb and is easily up there with the best NOS items.
These come in burst tested matched pairs and quads with all the original markings and government stamps.
