Romy the Cat has found another room. I’ve started a new fiction project under my name, Roman Bessnow. The new work is at MutationsBook.com

Risking that the topic has already been discussed and that I postin a wrong category (Romy feel free to (re)move this post:Is there any sense in trying 6C33 at higher volatges and lower currents?More precisely, I've been wondering if 1/2 6C33 @ 300-...

[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...

Dear Romy,it had been a while before I hv return to your goodself and here.The Meliq had been built according to your circuit. However, after a few days' breaking in period. The VR2 have issue and causing sudden increase of current... I think it migh...

[quote user="romy"]send you two 6C33C – a new one and the burned out[/quote]Please do. I have interest in the result myself and don't mind spending the time. I can post photos for each tube.[quote]a trace for the very given tube is “nice ...
|

Sadly I have never spent the time to try and correlate the sonics of a tube with the trace characteristics. Ok, sometimes it is obvious. A flat line is a dead tube. Normally I measure and compare both sections of dual triodes. ...

[quote user="drdna"] How about using the 6C33C for the low midrange-woofer, the 2A3 for the upper midrange, and the 45 for the tweeter? I suspect if each circuit can be optimized, that they can do their best within each frequency range. [/quote] Hm…....

[quote user="cv"]Not to start a pissing contest, but how are they wired (series/parallel?), and with what voltage across them? Something just can't be right; the makers spec is 88db / 2.83V, which is over 1W. Unless it's uniquely smooth room gain wit...
|
|
[quote user="cv"]...yes, I remember. I wonder if it's due to the large (and varying with signal) capacitance of the 6C33 input interacting with the small coupling cap. Hopefully this will be less of an issue with the 6e5p/6p.[/quote]Chris,
It is cer...

A site’s visitor sent me a link about the $100 per socket:

Despite of the semi-idiocy that is written in the promo material in the link the socket looks like the good one. I would personally would ...

Yes, well - I wasn't really saying much; just a vague hypothesis. There is some tendency for lower Rp tubes, (and somewhat related) tubes with a certain harmonic structure, to sound more romantic, and hence impart that quality to music regardless of ...

Sorry for making that video so large. Here it is again but 1/10th the number of bits. Compression can be a useful thing.http://www.hagtech.com/blog/media/6c33.wmvjh...

Romy,
I have a TV2 too, please can you tell me wich is the configuration/settings to test the 6C33?.
Almost I want to test filaments if it´s too much amp for the tester.
Thanks

Romy - Not sure if you mean increase the load above 550ohms, which would give you less power, better damping and possibly less distortion (trade off between how much you need to push the tube and the flatter loadline, also I suspect there is dis...

Sine I informed public about Melquiades amplifiers I receive many emails from people asking me about the operation points of 6C33C. For whatever reasons people mistakably took me for some kind of 6C33C guru, which is am not. Moreover I could be hardl...

(sorry, this is supposed to be posted in the questions and answers colume but I must be so stupid to have it posted here and now I don't know how to move it there.)Hi Romy,How are you! This is Welborne, from far across the ocean, Hong Kong. I have k...

Panos, it is not about convincing me. My standing is absolutely irrelevant in this subject – I do not sell audio and do not making living by evaluation of SET amplifiers. I report what I have witnessed, nothing more. Sure, it is very possible that y...

Interesting Romy, particularly the "echo" affect and weird overtones with the aircap. I wonder if the thing is picking up resonances and if the impedance issue is responsible for the overtones... signal being modulated by the varying input capacitanc...

Romy, Now you mention the issues here, I am thinking about what the differences in quality might be due to. I notice that you haven't explicitly said which is better, super or regular... so think of this just as brainstorming as to why things are... ...

Hi!English's not my mother language so I'd have advices to choose wich Melquiade could be the best for me...I read that there's a lot of different versions...and I wasn't able to email Romy because of the robot barrier.I've very good 95db Fullrange B...

Alas, not much time to deliver the promised treatise...So, tantalisingly, I will suggest this; for the range 1k up, you would have no problem getting a small mumetal OPT made suitable for the 6C33/S2 combination. Actually, I have something simil...

David, there are no different Melquides versions. Melquides is all about to use two-stage solution around cathode-ground 5E6P/6E6P with grid resistor bias where the bias voltage buffered by gas tubes. You can creates countless versions around th...

[quote]do two tubes at once then it make sense to have one selected reference tube[/quote]I see. Yes, the digital scope option would work. I have one, might try it out. With a 6c33, the VacuTrace has only enough power to trace ...

Ok, so should be burned in nicely. There are some theories around how mylar and similar interwinding materials (as used by Lundahl, if that is the OPT you are using) can need a fair bit of run in. This is more of an issue on eg input transformer...
