Delet if not proper topic. Was wanting to experiment with 6e5p driving lifeless speakers. with possible 100v swing i'm guessing way to much for regular garbage amps. What are peoples ideas for lowering output v (to like >5v?) with out destroying...

I am not the person to speak about the 6E5P but I have messed with hybrids. If you want LF power, I can say I've heard some pretty simple plate amps that "work" at LF. It would be helpful, and it might even be necessary for you to tell more about you...

people think you can use 6e5p single stage full range.
like for example

Hi ShannonI think that Romy have it already on his pre-assembled Zarathustra on this topic's pictures: http://www.goodsoundclub.com/Forums/ShowPost.aspx?PageIndex=1&postID=4121#4121and also here:on post #8http://www.goodsoundclub.com/Forums/ShowP...

No special bias sauce, it seems.

Hi Romy,The builder regards VR1 more like an "offset to 0" adjuster than a bias control for the 6E5P since its working range is quite narrow. He asked me to know from you if along the 6E5P's lifespan it needs further adjustments at VR1 or if a single...

Hi Cat,It seems the 6e5p is driving the transformer directly. I've used various versions of even simple mosfet followers to good effect at the headphone level, but never considered using a speaker level transformer. Did you and Dmitry cons...

Sorry, with me apparent alzheimer-inspired progressing dyslexia…. I’m keep confusing whatever is possible to confuse. What I meant to say was the 6E5P vs. 6E6P. The last one you have in DR version. They are essentially the same tubes with different p...

[quote user="ml8"]...but resistor between screen grid and plate, to my hearing, makes sound slightly unnatural, especially in highs.But this may be not true in your case (i didn't try to use this resistor with 6E5P, only with other power tetrodes), s...

I still would hesitant to short the scene and anode and it would require a very sever control of the tubes. The problem is that it would be necessary to do not only then they new (it not too difficult to put then before a fast scope and to see if the...

Dima and I spent today quite a time experimenting with different operation of the Single-stage Milq. We drove it from my Fluke 409D with resistor bias, loaded with 12.8:1 into 12R. Playing with bias, voltage and current we tried to find an operation ...
|
|
Now I re-listen all the things the we try to measure. To surmised everything I have to tell that Dima’s way to looks for optimum operation point of the tube (setting balance for voltage vs. current sufficiency) turned out to be very successful as I d...

[quote user="KOTriode"]Romy,I looked at your Melq schematic : http://www.goodsoundclub.com/PDF/Melquiades_SET.pdf regarding the 6E5P bias. Would it be simpler to use two alkaline battery in place of R5 to provide 3V , or 3 Rechargeable for 3.6V ...

Frank Blöhbaum, from Sweden I believe, have designed for Thorens a preamp that I think the first outside of Russia commercial use my 6E5P tube.

[quote user="ml8"]That's true that this resistor have negative impact on sound quality. You can run your 6E5P without it as long as you do not get parazitic oscillation.Just connect screen grid and plate electrodes right on tube socket, using shortes...

[quote user="KOTriode"]Ok, I just read your "Melquides Remote biasing". This technic can not be duplicate in my amp due to DC coupling, the C3G (I dont use 6E5P) driver stage basically adjust the 6C33C current in the output stage. Just for curiosity,...

In my post above I have mention that Srajan is in a way a brainless parrot that repeats the heard and has no ability of desire to understand what was the noise about. His comments that 6E5P and E810F are “close electrical” is a good indication how it...

The basically the same tubes. The 6E5P has own unit pins layout with heaters connected across the tube – very moronic in my view and it does not allow twisting the AC filament wires to the very end. The 6E6P has a common pins layout that most of west...

[quote user="Romy the Cat"]Why do you think I bout a 1000 of them and closed to the rest of my life my interest in driver tubes?Still, the 6E5P should not be measured as a driver but heard as a driver – the beauty in this tube is in its sound.I do no...

I did have the Déjà vu feelings about it as I felt that we had this conversation in past. Here we go – it was a year ago.

[quote user="hagtech"] Stepping back a moment, I'm guessing this tube is designed for radar operation. Maybe in an aircraft. The spec sheet definately talks only about pulse mode of operation. Maybe it was a driver for a pulse radar...
