Well, Chris, my transformer is amorphous type but I would have difficulties to comment about the progress of the burning. For the first couple weeks when “Melquíades” was born I have difficulties to “get” how to load the output stage properly a...

Yes, it is what it is. I spoke with Dima last night and he passed his view on the subjects. He does not agree that 24 bit really exists in out 24 bit converts. He feels that we get 20-22 bit in the very best cases. He also think that all our 16-bit c...

The Rohde & Schwarz EU-6201 tuner was made for German Ultrakurzwellen (ultra short waves or FM) Broadcast Network. The idea was to have a chain of wide-bandwidth composite signal receivers that feed re-transmitters. I made an attempt to accommoda...

I juts got home, put a record to play and suddenly discovered that my SPU has it’s cantilever bent 90 degree and then even twisted vertically. It was perfectly fine last night!!! I have no idea what kind forced what appl...

OK, first off all I have moved the latest posts to the “How to drive 6C33C” thread.
Regarding the operation point. My initial intention was to give Melquiades’ output as ML2 did: 175V, .310mA. What is important is to understand that for LF channel I...

Hi Jack , it's very interesting ! [quote user="Jack 14"]When I was younger -35 years ago-, I have observed the glowing of a NEW VR tube (it was a 0C2) for few hours (ok, I had nothing more interesting to do then..) and seen that at low currents,...

I did today some interesting listening. I took my SL-CT470 walkman and plugged it directly into the Baby Milq amp. It was fan. The Baby Milq has no bass now and all together sound kind of screwed but the dynamic capacity of that entire set really imp...

I do not see any major changes coming in 2009, nor do I feel a need for them. Recalling all my dids and my thoughts here a brief outline of Audio Projects that I will be involved in 2009 and of cause anything else might come alone in future…

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 ...

Yes , I told Romy about this funny idea , which is quite simple of course - to make a simple SRPP stage on special hi-voltage tubes , powered with high voltage supply ( 10000 V , for example ) and drive the electrostat panel directly from the output ...

[quote user="morricab"]Well Romy, IMO they are not just tonally different they are more tonally correct, ie. they simply have less coloration than other technologies. Just listen to a recording sometime made with a ribbon microphone and you wil...

I wonder if anyone make, commercially or otherwise, any (good sounding?) a two-stages classe “A” hybrid running 100-200W into 8Ohm, with no feedback? AcousticPlan looks like tried to do something but their amp is just 50W and it looks they have...

[quote user="DHT4ME"]Romy if you feel that you are not loading the tubes enough put a 16ohm power resistor in parallel w the S2. this will cut the load line in half. It should be less wiry and stronger more weighty sound. Obviously you might experime...

[quote user="Romy the Cat"] In the 2008 I have a few immediate goals:
1) Finalize the 6-chennals version of Super Melquiades and integrate it with Macondo

3) ...

[quote user="Romy the Cat"] As now the Rohde & Schwarz + T-85 sound just wonderful and I would not look for other Multiplex Decoders with exception of a future idea to built one even better (with L de-emphasize) INSEDE of the Rohde & Sc...

Ok, I do not know what it was: was it DHT, was it 300B, was it some other specifics of this given amp or whatever… but those two aspects that I named: intentional density of colors and randomness of pace are something that I would like to exercise in...

Jessie, absolutely wonderful. Dima used the very same techniques to build his own MF horn. BTW, I made in past a prototype horn with similar idea that ended up disasters because of my stupid “willingness”. While I was applying plaster I spared ...

Hi Dima,Yep, I really think that I get this one right: I never take the time to do any research about it until your posting came. Luckily, I got the clues in less than 15 minutes. If only other things can be like that...About VR tubes stability, now:...

Hi all ! [quote user="morricab"]
Hi Romy,
Could you explain a little more about the amp? If I understand you correctly it is a 1 tube stage with solid state (Mosfet or Bipolar??) output. If it is Mosfet then it is likely to be running w...

While Dima and I were thinking how to get out of our 7788-7721 80dB gain, a visitor in reply to my inquiry above about a “second-type” phonostage sent me a link that make me very much queries. He suggested looking at DACT CT-100 phono module. It is r...

T, The phrase “"no measurable jitter” was actually the Ed Meitner quote and it was he himself who claimed that his transport and his DAC bound together via his C-clock interface have no measurable jitter. I have no reasons to disbelieve him regarding...

It was a bit tricky to make it works. The Schwarz original crystal is imposable to get and the new one that I got from ICMC had different internal capacitance, so I was forced to shut them with additional inductance to let the oscillators to fire up ...

Hi Jack ,Thank you for your very educational info ! It looks like you are right , and your tubes are rebranded SG13P .... Maybe a big stock of those tubes were exported , and you know them better than we do :-)And another question . You wrote :...
|

Thanks, KM
It makes sense but I do not like to burn those tubes at max plate dissipation. How about if I put one more RC chains in PS and drop anode voltages from 400V to 350V? Then if burn let say 60V in cathode then I arrive to a comfortable...

Shannon, I am not 100% sure what you are asking. If you want
to drive SS with a single 5E6P stage then you have some difficulties. Dima had his version of SRPP with 5E6P to drive his SS and it "worked" very fine. http://forum.vegalab.ru/showthread...

[quote user="Romy the Cat"]
Dima for instance (and he has quite high expertise in the subject) claims that there no true 24bit converters available anyhow. BTW, with all advances of HDCD, that I fully appreciate, it makes send only on 16 bit. At 20...
