Inhaling Melquiades for long time. But have feeling about dset again. Started experiments years ago and abandoned. have full one stage 6e5p blocks all proper Melquiades way. except misplaced output trannys or maybe never had right ones. What Amorph...

I Forgot they did this. I only have experience with se driver stage. You would remove r3 and c1. change r2 to 10k and put the bias voltage from the gas tubes across it. I would try just regualar zaruthstra srpp circuit first. Like do you know it wi...

thee srp in Zarathustra is cathode bias, melq is grid bias. If gas biased the srpp it would no longer be the circuit in zarathustra. what would this do to sound i have no idea. The function of the gas tubes in melq are not only for providing bias. ...

Congrats on the new brats. And family. How things have changed. Even though Amy has introduced sound problems I appreciate the decoration efforts. Also the Angels playing strings tapestry is magnificent. So did you ever get Zarathustra functional...

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

stiff sound aside what about the b...

Ive heard you mention copper air caps before. Do you have reason to think they would actually make any difference vs alu....

looks like heater inductors wrong label on the 834ptf schema. But i guess we dont realy need chokes anyways. ...

when talking ulf are we talking array of aura 18(the old ones not new junk), or something else...

My wording was bad. I am building zarathustra but am a long long way from completion. I do not have the capabilities to just whip one up. Yes the 6n1p was from the old days when i thought i had discovered good sound, i'm sure i still don't know(but...

Had some fun experimenting with 6e5p driver stage.playing with difrent output transformrs and resistors found that the stage can drive a speaker with ground connected to air. mabye this is widley know i did not know. + of speaker connected to bad ou...

[quote user="Romy the Cat"] A few months ago I bought the first pressing of the same album… only sealed (paid $60 - love Horowitz in the end of 40s begin of 50s)... and you know what? Suddenly the entire album could be perfectly tracked with the cont...

Bonkers says thanks for the compliments he is always been interested in audio pursuits. Been a while since he's had anything interesting to rub against. I wasnt paying enough attention. The gas tubes never made me feel the same way as Melqui...

couldnt get "insert iamge from gallary" to work so i attached it. Had it working for a couple weeks. Single stage 6e5p testbed. The B+ rcore and output transformer is underneath. In the end r23 of 30k worked with 30h choke. no choke on gas tubes...
|
|
Some few 6e5p have black dull getter not shiney chrome getter. never been used and they still test normal. do they sound any different? ...
|
|
I will be fallowing the proper formula, except no chokes on gs tube supply and 30h on b+. I got that far and couldn't find the gas tubes. So untill later thats it. ...

Had a small amount of free time tonight. 150vac secondary, fred, 100uf, 500r, 1000uf, 30k, 5k, (like melq schema 4.4) no load voltage(b and c test point with no gas tube) 226.2vdc both lines. secondary is actually putting out 171.6 so 226.2 makes s...

[quote user="Romy the Cat"]3) There is a mistake in Milq circuit. The B+ of the driver stage has almost insufficient amount of critical inductance. It was because I drew the circuit having the Super Milq in my head where the PS was feeding 3 stages a...

I figured there would be difficulties. Thanks for the link, 117 pages of Russian, wow. Transformers came to mind. i did not know if such transformer could be made. 30:1? with wide bandwith. amorphous? I think i have ribbon mic transfo with ratio l...

I do not think that 6e5p driver stage withh ss could be useful for proper playback. or would it somehow be melq.
I am familiar with the proven method. in the case of melq it should be followed 100% exactly. I am very greatfull for ...
|
|
You understand. that is what i want to do. This is not exactly for my present playback. I hope to gain more understanding the 6e5p. Also experiment with higher power Lf. ...
|
|
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...
|
|
people cant handle that it must have no cathode resistor. That r2 must be 15k. that gas tubes must be used but not for regulating voltage. etc.etc. well if you want good sound anyways. I think many people probably have built it. It is so ridiculous...
|
|
5) You might consider do not make a dedicated PS for positive bias but to take it via a resistor right from C2 capacitor. I did it and I did not see any worsening in sound.
