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...

Romy,
I assume you plan to use one of these as the driver tube. Do you distinguish any difference in the sound between the two tubes? I am curious as I have been looking over a big pile of them and they respond quite differently regarding vibrat...

BTW, how stable 6E5P is? I'm asking as I was contemplating biasing the output by the voltage drop on 6E5P's plate choke (DCR is say around 1k),with only some minimal autobias on the output. The drawback is that any drift in the driverwill rebias the ...

Not quite on topic but perhaps this deserves to be here:http://www.theaudiophile.net/threads/762-Lyrita-s-new-Mono-amps-and-DHT-Preamp?p=7735#post7735It appears to be a simple two stage SE design with the 6e5p coupled to the GM70 via an interstage tr...

[quote user="Antonio J."] 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 adjustment...

I think it should be somewhere posted for my and perhaps for others future references. Here is the setting for testing Melquiades' single-stage tubes on Hickok 580/580A tube testers. To test the tube as a driver for a full Milq (two stages) set ...

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 not know why it gave to y...

Sometimes my time will come and some of you will try the 6E5P as a driver, properly used. Then, if this person has a sensitivity and rudimental audio intelligence to recognize some unique 6E5P’s sonic signatures then he will find interested to reread...

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...

Taras Oleynk aka “ML8” sent me a couple months ago his measurements of different driver line-level tubes including the Melquiades’s diver tubes – the 5E5P. I am posting his data here with his permission, including Taras’ statement that is JUST PRELIM...

Here is a document in Swedish language that describes its authors’ view on 6E5P. Since the author extensively use a park of Russian tubes I presume that he is Russian descent.

[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="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,...

[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...

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="Chirag"] 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 D...

[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...

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...
