This adds to the input signal and will be amplified by the tube. Main thing, the tubes work, and if it goes wrong we replace them, they say. What is the best EL84 to buy?

The lower microphonics are reached by using double layer mica, which gives better stability to the system. Even so, Chinese factories make it a sport, continuously tweak the processes for using cheaper materials, and leave steps and control away.

The longer lifetime can be achieved by using more expensive materials. Then you end up with tubes that have dataxheet parameters for everyting. So whatever the situation, I prefer such lots that have not been picked from. This “resistor” injects a 50Hz ripple signal from the filament to the cathode.

They throw nothing away. They do not throw away tubes that are on the edge of the specs, but also not throw away over-stocked or not so well stored production materials.

The 6P14P-EB deals with all of these problems at the same time. With standard EL84, plate current ranges from an estimated 30mA to 90mA. Matching in pairs or quads in included in the price.

EL84 Only differences are listed here when identical, it is not listed. So if parameters of a lot are the same, the higher datasheft you can have to the base quality of that lot.

Only differences are listed here when identical, it is not listed. Now, for the 6P14P-EB Hum will start at kOhm or ddatasheet.

If you know about tubes, you will immediately recognize the is very special. This tube used to be very expensive when it was made! This picking makes little sense, but it does get a problem when stocks have been picked from multiple times. These low cost materials produce contaminating datasheef when the tube gets older. This is really special. It was never before available for commercial use.

A similar situation we have for the Philips EL84, also a fantastic tube, but expensive. Perhaps not many of the readers had the chance to compare lots pcs original packed NOS tubes with each other, or compare such lots with pcs of new made tubes.

If tubes of a lot appear all identical, this promises best quality. This lot may have lower lifetime, and problem rate is highter. The table below is an extract from it. 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 datxsheet that he sold. So I make a distribution, and then I see immediately of some values are missing.

Like a box of getters was in contact with air too long, etc. A good alternative is the EI Datssheet, which sometimes can be found.

WIth the tubes comes a four page original printed data sheet, listing in full detail the excellent specifications of this tube, in Russian. The tighter tolerance for plate current can be achieved with simply better adjustment of the tubes, before putting them in the glass bulb. Also vice versa, this applies. The standard EL84 has actually not a very high lifetime, it can be microphonic, and is produced with an eatasheet unacceptable wide range of plate current.

This will lead unavoidably to a wider spread in tube parameters. Actually it makes little sense, but some people pick out the center values, as if those are better. 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.

Or better said, dataheet use lower cost materials, of which the low cost EL84 is made of.

NOS stocks of this tube have been released for public sales only recently, and stocks are low. In that was sure Telefunken.

So I take from tubes randomly 6 tubes. After hours they begin to wear out, and they are worth not much any more.

Others pick out 6pp14p higher DC current values as if those are better, and if somebody has a Hickok tester, he’ll pick out those with higher transconductance as that’s all he can see.
