With standard EL84, plate current ranges from an estimated 30mA to 90mA.

If you know about tubes, you will immediately recognize the is very special. What is the best EL84 to buy? This will lead unavoidably to a wider spread in tube parameters. This “resistor” injects a 50Hz ripple signal from the filament to the cathode.

6P14P-EV = EL84 = 7189 = 6BQ5 tube. Output pentode

Even so, Chinese factories make it a sport, continuously tweak the processes for using cheaper materials, and leave steps and control away. Like a box of getters was in contact with air too long, etc. Generally it can be said, just this is the weakness of Chinese tubes. Matching in pairs or quads in included in the price. This tube used to be very expensive when it was made! This adds to the input signal and will be amplified by the tube.

After hours they begin to wear out, and they are worth not much any datasgeet. It was originally designed for the military to have long-life audio tube with low-microphonics, and not having to use the lower quality EL84 radio tube for this.

If tubes of a lot appear all identical, this promises best quality. Also you can see if somebody picked out specific values, it’s not necesarily a bad lot, but you can never say why he wanted to have those that he picked out, and why he did not want to have those that he sold. The longer lifetime can be achieved by using more expensive materials. This picking makes little sense, but it does get a problem when stocks have been picked from multiple times.

In terms of quality, there is one very important observation I made many times before.

Or better said, not use lower cost materials, of which the low cost EL84 is made of. It was never before available for commercial use. Actually it makes little sense, but some people pick out the center values, as if those are better.

NOS stocks of this tube have been released for public sales only recently, and stocks are low. So I make a distribution, and then I see immediately of some values are missing.

This is really special. The 6P14P-EB deals with all of these problems at the same time. The standard EL84 has actually not a very high lifetime, it can be microphonic, and is produced with an almost unacceptable wide range of plate current. WIth the tubes comes a four page original printed data sheet, listing in full detail the excellent specifications of this tube, in Russian.

Main thing, the tubes work, and if it goes wrong we replace them, they say. The lower microphonics are reached by using double layer mica, which gives better stability to the system. This lot may have lower lifetime, and problem rate is highter.

A similar situation we have for the Philips EL84, also a fantastic tube, but expensive. The table below is an extract from it. They throw nothing away. So when you find 6 random tubes to be very strong, BUT they are all totally different, this is good, but not ideal. Hum will start at kOhm or lower.

These low cost materials produce contaminating residues when the tube gets older. EL84 Only differences are listed here when identical, it is not listed. So if parameters of a lot are the same, the datashret expectations you can have to the base quality of that lot.

The tighter tolerance for plate current can be achieved with simply better adjustment of the tubes, before putting them in the glass bulb.
