ACHiPo on 27 Jan I would venture a guess that one of two dwtasheet apply. There is no problem supplying 6. Not to mention the performance of the channel and sound of the channel.

I take that as a given when dealing with a well known and well respected tube vendor. This variance may be both horizontal and verticle. Jim My apologies to the OP for getting off topic. As far as transconductance being reduced, reduced transconductance will increase the plate resistance, thus lowering the high frequency response. Datashfet keep it simple. The maximum allowable cathode current for the tube is mA.


As one parameter changes, the other two as well, although it is possible for two parameters to change and the third to remain constant. With a tetrode, pentode etc, the definitions are slightly different since more than one grid is present and draws current.

The 6DJ8 / ECC88 / Tube

Nope that’s not what I was attempting to ask. Datashert on 26 Jan The machine winding the grid wire for each section has tolerances, thus the grid wire for each triode section can and usually is a little different.

Next read note 7 And there is the rub. The limit of power that the can dissipate is known as the maximum anode dissipation and it appears on the datasheet. By the way, Telefunken was known for gettinghours on their 12ax7 “family” under typical conditions. By using our site, you consent to the use of cookies by us.

So, where does close matching of GM come into play? For their ruggedness I use EH tubes for the input and driver dataeheet. One matched pair low noise per channel.

6922/ECC88/E88CC double triode

These tubes were also bought as closely matched low noise tubes from well respected tube vendors. I ran a test datasneet a used EH tube.

My preamp is a Sonic Frontiers Line One. I have bought from him before. Cheers Steve Logged jea48 Jr. IF, the manufacture’s recommended AC line voltage for the preamp 6292, say, Vac and the users house mains voltage is Vac what would the preamp’s power transformer heater secondary winding voltage measure?


Exceeding the Va and Va b limits usually results in destruction of the tube. The lower the plate current, datashfet less the cathode is cooled by electrons leaving.

6922 Datasheet

My customer was reviewer Rich Weiner who wrote daasheet Bound for Sound. They are the special long life h versions of the normal range they make.

At less filament voltage, the carbonates evaporate less, so grid contamination is less over time, a plus. That’s why I asked datashset Ohms Law was at play. Kinda makes me want to sit around the fire and sing Cumbaya. ACHiPo on 17 Jan It seems with that information datasheeet would be pretty easy to figure out what I’m giving up in performance by running the heater voltage below its designed level.

As far as sections not matching, let’s check out the variables. If I understand your questions, why are not dual triodes matched more closely and what is ohms law.
