[quote user="KOTriode"] Thank you for the comment on this amp, this is my first time of using the 6C33C tube, I decided to build this amp after reading about the Melquiades, this amp is just a quick experiment on the 6C33C sound, since I have a s...

With 6C33C output run at 40W plate dissipation, this amp run much hotter than an 845 amp with output tube running at 100W. I measured the hottest point on the bulb and it is about 380F. I guess the due to short bottle , the heat spread on the ch...

The transformer in this preamp was given from a friend who want to learn how to wind transformer. If I remember correctly it started out as UBT, they were bought (when UBT was operating in the Silicon Valley) at the company swap meet. They were rejec...

There are a few manufacturers out there, Minus-K, Halcyonics, Vibraplane...The Vibraplane is a good unit for the money, I have no problems with it and it does the job the way it should.Those Vibration units work different from construction and are ve...

I think when we are taking about the today TT we do not mean inventions – there are no inventions that I see in mega-priced turntables. All that I see are small manufactures, very inefficient production, very little market for sale and distribution a...

Hello Romy
This is my first post. Did you take courses in electronics and mechanical engineering or have you learned yourself outside of a structured environment? I am very interested to become proficient in working on/modifying my own electronics. ...

[quote user="Paul S"]Romy, I have noticed the same thing with the phono stage power supplies, that the big multi-chassis units with dual 100 lb. PS get no overall sonic advantage, all said and done. So how do we deal with the stupid, lousy AC that is...

Yesterday my machinist informed me that the End of Life Phonostage’s chassis will be reedy next week. So, I desisted update the power supplies of the thing replacing the FRED diodes with those no reverse/forward recovery Silicon Carbide Schottky diod...

The two stages 7788-7721 phonostge can go at near 70dB and it were what I was intended to put in that Chinese chassis. I would like 6-10db more. A transformer? A semiconductor gain stage? A third tube stage? I do not know…
Actually reticently, two s...

I am with you on this one. I am also very suspicious of gigantic, 4-chassis phono stages if only because I just wonder why the need for all those damn noisy parts, along with concommitment connections?So it really pisses me off to admit that th...

In "High End" today we can see nearly every possible Design and obviously it seems that we find for EVERYTHING a fanatical Fangroup.Be it Tonearms made of Wood, or Plastic (of course it has a different, more important sounding name), multi speaker ch...

The ideal "star" grounding plan is seldom realized in practice, for lots of reasons. For one thing, it takes serious concentration to really think it through. As I have said many times, it is often useful to have a "bleeder" on the chassis, and this ...
|
|
If you can do it, try isolating both cases/chasses from your "ground plane(s)". Use one inclusive "ground plane" for both the PS and the gain/RIAA sections, and ground this "ground plane" to the house "neutral" wire. Do NOT connect any shielding to t...

Hi. First time posting. I had long admired an older friend's RX-5000. He left it to me when he passed last year (RIP, Bill) and I recently got possession and did a lot of cleanup on a table that had been sitting for a couple of decades. He has ow...

Dear Romy,
The engineering basis for the K-LEVEL feature of the K-Stereo machine is described in Bob Katz's US Patent Number 7,076,071 "Process for enhancing the existing ambience, imaging, depth, clarity and spaciousness of sound recordings". ...

I you play the video full screen and place the cursor at the top or the bottom edge of the platter, it seems clear that the the platter wobbles since they go up and down synchronously and the upper edge of the turntable chassis is not moving at all....

I must say I've never came in to intimate contact with cables and avoid it untill I can, so yes all my arguments are theoretical.By amplifying I ment of course voltage, not power and ass-u-med that the external noise as well as the cable distortion a...

I was asked for more information on my power supply regulator, which allows the original 100V power line (Japan) to be plugged directly into a 120V line (US), while greatly smoothing the ripple going to the motor.

I would contend that most of the microphonics and feedback in valves is usually caused by the resonances and vibrations of whatever they are plugged into. Glass is very rigid which is only enforced by the shape into which it is mol...

Spend a good few hour moving the boxes, connecting the cables
and do other sort of things. Was looking for elegance and more symmetry. The
objective was to put midbass channel between the main horn islands and set the
horns, the midbass and LF in ...

Thanks, LBJ
It is useful. I had also an idea to have a port mounted on removable plate in order to have the port side changed. I also, very much inclined for the yellow version, even my reasons are very none objective and I based my superstitions on...

What you guys are missing is a grand scale of the concept. You are talking about voltages, implementation, electric chairs and the rest of irrelevant crap but I am talking about the pure inspiration from the concept. No one runs to solder anything. I...

Bill, when you were at my place I use two PP2000 running together as at that time I did not discover the effect. I was running my MF at -2dB and my tweeter at -1.5dB. As now I use one unit and I return back my MF and HF channels to the level as they ...
