Look at the solution in a different manner.Regeneration will typically not be able to service large power transients thus, they are best suited to SET, i.e. constant current systems. Similarly any control loop cycling will usually be heard...

Measet, I will try to find a photo and the schematic as you requested, but it may be a while before I can locate them. Plus, we are still digging out from Hurricane Irma down here. As I recall, I beefed up the raw D.C. supply and then used an LM317 r...

If i am not mistaken It seems Most High Power UPS in the market like APC or ABB are not good for high dynamic loads (high crest factor like Music signal) and the load transient response of these UPS is not very good at rated power. APC , ABB and ... ...

[quote user="manisandher"] Also, when I switch from AC to battery, the output voltage (as measured by a true RMS voltmeter) INCREASES by between 3-4V. Now, I am NOT suggesting that this increase in voltage is causing the difference in SQ. However...

This week I will be trying to address why the Milq midbass is clipping. This is very interesting one. Currently the Melquiades LF channel uses an output transformer 700R to 5R or 11.83 to 1. I thought before that I have much lower ratio, like 5:1 bu...

Paul,
I tried this tube in few other amps and also on a phono amp and I like the sound of this tubes, perhaps it matched with the speakers/amp combination better than other, still there are lots of other tube out there that I would like to tr...

I run both of my Reference and Daily tonearms into my “End of Life Phonostage”. As I told I do not know any way to commutate signals at phono level signal and I just re-plug the phono cables at the phonostage’s input. I have no problem with that ...

Romy,
can I suggest you read about the amplifier in question before making comments?
The unit uses four tubes per channel - three drivers and one output tube. The unit has zero negative feedback. It is as pure as they come.
Directly heated ...

I was tested the amp in “integrated” mode and even I do have very low noise from the DHT tube but with my sensitivity and with my distances I do hear some ugly noise. I did not realized that the nose is moderate when I lose 3dB of my MF attention...

[quote user="Paul S"] After a few minutes, I checked the amps with a (Fluke 189) DMM, just for drill. Voltage was set down to 175, but current was about 450 mA. Dialing down the pots, I could not get the current below 390 mA, even t...

[quote user="Paul Costa"]Aparently the new powersupply for the motor makes it sound even better, but I have not heard it or the three motor. I would like to hear the three motor but really do not have any interest in owning it. Much debat...

I did not play my playback since Sunday and turned it last night after 4 days not being off. It was very pity sound. Even I felt that it was getting better after 2 hours I shut down the system as I has other things to do. In the past I have mention...

[quote user="Romy the Cat"]Manville, just for sake of an experiment, I’ve sent one of my “worst” performing S2 drivers to remagnetize it. I do not know if it affect the ‘beneficial resonance” and if it does I will report the results of its performanc...

[quote user="jessie.dazzle"]I should mention that with all the wonderful things it does, the L2 (preamp) definitely deserves a fresh pair of 12AX3s and a 6C19P. (I have not changed them since starting work on the horns... all tubes are exactly one ye...

Floyd,
Regardless your preamp uses output coupling cap you would still need a positive supply. Positive supply compensates the negative DC voltage at the amp’s input. Theoretically if you do not connect or disconnect the cable between your preamp an...

Here are some my ideas for an “Unlimited Turntable”. Feel free to share some of your ideas… An “Unlimited Turntable” should allow multiple arms. It should be a good quality arm with a good stereo cartridge…. Also, it should be a good quality arm with...

Well, I am not a big fan of plasma tweeters.
First, of all they generate a health hazardous gas while they operate. All contemporary plasma drivers have catalytic converters that presumably convert this gas into something neutral. The process of con...

Thinking about the integration scenarios of my midbass horn I come to a realization that it highly possible that the horn in THIS room will do something very unique. I have wrote before that I was successful to set channels delayed but the delay ...
