Have curves been published for the 6P3S-E in quasi-triode? Most power tubes don't allow connecting both the screen and suppressor to the anode, so I'm curious how it performs. Alternately, has anyone here taken distortion measurements on this tube in triode mode, either PP or SE? This is something I've been meaning to get around to myself, but just haven't had time.

It can't be connected to the anode. Which triode configuration did you use to test the 6P3S-E? Did you by chance compare results with the suppressor on the cathode VS. anode?

Michael Samra Dealer Posts: 36118 Location: saginaw michigan Joined: January 30, 2005	Jack I understand that but its the actual beam forming plate that connects to the cathode,not the actual plate. i think the 6p3se also has its beam forming plate connected to the cathode.I did the test in standard triode with a 100 ohm resistor tying plate to screen grid.

I swear I looked it up last night and found a basing diagram with the suppressor grid brought out to a separate pin. I can't find that now though, only the diagrams showing beam-forming plates internally connected. So... nevermind, I guess. Thanks for the info regarding triode mode being similar to the 6L6.

I believe this is what you maybe looking for:

What's up with the crazy prices on Stratotones? I had a '65 that I bought new, played it five years or so and couldn't wait to get rid of it. Strings too high, tone sucked, wouldn't stay in tune - all around, a really cheap guitar. Eventually gave it to a friend and bought a used Jaguar. What a difference! Anyway, I see Stratotones on eBay now at $600 and up. Do sellers actually get that kind of money? Something's really wrong with this picture...

Here's the model & color I had (makes my ears hurt just lookin' at it):

You got me. But, there is a kinda retro-look wave going on that started with Indie bands. Check the prices of some used 1960's Danelectro guitars. Kinda cool website.

Here you will find all the necessary data for 6p3se, as well as an example amp 6p3se 20 watts in triode.

I should note that everyone who uses a pentode 6p3se badly mistaken, choosing the 3400 ohm load, and the need to select 2300-2500 om!!!

6p3se closer to the optimal load impedance to the EL34, but not 5881. 5881 corresponds to the parameters 6p3. I have a lot of information for 6p3se ... As ever tell, if needed.

Triode_Kingdom Audiophile Posts: 10049 Location: Central Texas Joined: September 24, 2006	I'm not able to download the files you linked to. Can you clarify the graphs you posted? Are you saying that the 6P3S-E in Triode is similar to the EL34, but the 6P3S-E in Pentode is similar to the 5881 and 6L6? Thanks for the triode curves; what is the source of that data?

If you like being deceived, then use the wrong data, thinking that the graphics match 6p3se 5881, as many do:). I gave precise information from the laboratory of the firm. Data are taken from the original documentation, it is still our Russian lamp and who does not like us to have all the information about 6p3se. I think you are very easy to make graphics for 6p3se in triode, making the measurement is very simple. 6p3se in pentode is very close to the optimal load to the EL34, but not for 5881 and 6p3s, as many mistakenly think, and correctly applied. In a triode the optimal load is also similar to the EL34, but it all depends on the regime and the specific application.

tubestar Audiophile Posts: 9 Location: Crimea Joined: January 23, 2011	Compare yourself with the curves for 34. My friends band is easy to replace a Marshall EL34 amps at 6p3se(in the pentode).In triode 6p3se fairly high resistance Ri = 1,2-1,3 Kohm, which is higher than the Ri = 0.7-0.8 Kohm for EL34. I think that I gave you rare information that is very hard to find. my life is hell but your life isn't better!

I had previously assumed that the 6P3S-E in pentode would be most similar to the 6L6, 5881, etc. That information is only from word of mouth, though. What you have posted will cause me to do the comparison myself later this year. Unless someone else posts data first (such as output power VS output Z), I will compare the 6P3S-E to both the 6L6 and EL34. I have a fairly large stock of the 6P3S-E, and they would be much more useful to me as reduced-power substitutes for the EL34. Thank you for providing this information!
