Bas, try searching on 6P1P-EV instead.
I built two SE amps with it, "FireFly Single Ended Tetrode" and a PP amp "Sven 6P1P PP".
In addition there is info in the Meng Yue Mini thread.
I just looked up the Sven 6P1P PP Amp thread, and that amp has been running for three years now as the main upstairs amp. I've never gone back and touched anything in it. I should clean up the PS (change from 1N4007 to lower noise diodes) and try LED bias for the input stage.

Hi,
as this tube is a 6AQ5 clone in a different package, any search for this tube (or 6005, or 6V6) will do.
Best regards!

Hallo Kay,
I know. But I was wondering if someone has used it in a hifi amp. And if it really sounded like a 6v6. Guess I'll just get a couple and try for myself.
Kind regards,
Bas

Bas,
I have built both SE and PP amps with it.
While working on the Sven 6P1P PP amp I pushed several to see what they could do.
I've also tried in vain to find a western tube that is the same.
No, I disagree and believe that the 6P1P is not a copy of any western tube. Rather, I believe it was designed from the ground up as a new tube design.

6P1P characteristics look identical to 6V6, but of course the 6P1P is a 9-pin mini, so that is different. 6AQ5 is also identical in characteristics, but is in a 7-pin mini bottle.
At least that is what I have been able to find out from reading spec sheets...

Here is the specs for comparison. I agree that all three tubes are similar, but believe they were each designed individually and none is taken from the other. Look at the mechanical construction and one can see that the 6V6 plate would not fit either of the other two envelopes. Likewise the 6P1P/-EV would not fit in the 6AQ5 envelope.
Both the 6AQ5 and 6V6 have much higher max Ik as both were designed for vertical deflection service as well as to be used for audio output.
The 6AQ5 is a beam power pentode, the 6V6 is a a beam power pentode, and the 6P1P/-EV are Tetrodes with the characteristic kink in the plate curves.

Ah, that is a major difference. I guess I'd missed that very elemental characteristic. Thanks.
I wonder if that will make a difference when triode-strapping...
Triode strapped the kink goes away.
Curves are very similar for 6V6, 6AQ5, and EL90. The 6P1P bias is close but off more than the others. 0v bias for 6P1P at 200Vak is 83mA compared to 90 to 93 for the other three.

russians also say EL90
They're lying...
Isn't EL90 the Euro equivalent to 6AQ5?
That's right!
Best regards!
The Mazda-Belvu 6AQ5 Datasheets is headed 6AQ5 with EL90 directly below it.
I think that pretty much confirms that the two are the same.
Since the 6P1P is not a 6AQ5, it is also not an EL90.

EL90 and 6AQ5 are different names for the same valve. Whether it is implemented as a pentode or beam tetrode may depend on the manufacturer. 6V6 is usually a beam tetrode; it was developed as a cut-down version of the 6L6.
I think some ebay sellers offer the 6p1p as an 'EL90' but it can't be as it has a different base. It may be electrically equivalent. There is also the 6BW6 which is a Brimar 9-pin 6V6-alike; different pinout from 6p1p IIRC.
Apart from minor differences like capacitances and maximum power dissipation all these valves can be regarded as the same, so any circuit for one can be used for any other.

I should translate that one, as it appears to have a lot more information than:
electron Tube Data sheets - 6
electron Tube Data sheets - 6
what is maximum plate voltage you can get away with ?
how do they sound in guitar amp compared to el84 please ?
thanks bill
