It is know that in addition to basic tastes (I believe bitter, salty, sour, sweet) of the Western culture those “different” Japanese people recognize another taste they call it “Umami”. Umami, if I am not mistaken, is a sense deliciousnes...

The value/type of the capacitor after the gas tube hugely affects sound. I made quite a number of experiments in past with those caps and I have no idea why it is so. Well, I hardly understand (and I did not see anyone who does) why the “gassed resis...

[quote user="hagtech"]I have not tried this tube yet. It might push the limits of the tester. The 6.3V heater current supply is nominally rated at 5 amps. It might be ok to push it to 6.6 amps. I have to think about this, make...

Haralanov,
I would not make any assumption about be’s friend who proposed that the heating up magnet describes the major difference between perm and electromagnet. In fact what he proposed I find very stimulating and to a degree might be very ...

I spoke with various people about availability of upgrades for Sansui TU-X1. I have to admit that I have no problems with it sound and my concern is purely intellectual – there are better sounding resistors nowadays and there are better caps then ele...

A few days back I got rid of the 60-year old Germanium glass diodes in the REL detector and put in there the regular 1N4148 4pF low-signal diodes/ it was quite positive improvement. I need to be said that detector diodes are not the regulars diodes b...

[quote user="Wojtek"]has supposedly very nice Obbligato line of film HV caps . [/quote]
Thanks, the high nominals the have only 630V and they are larger than I would like to have. Does anyone know how those Obbligato sound in PS?

I know – it idiotic even for my site but it us what it is. I do not think that I can generalize my observations as I have not a lot of experience with DHT tubes but one thing that I have been observing for the last week is really arouse my curios...

A few more very simplistic measurements to extend on my comments. Here is the raw wave from the wall:
Here is the PurePower with 0W load
Here is the PurePower with 50W load
Here is the PurePower with 700W load
The load that I used everywher...

[quote user="Antonio J."] Regarding the C2 thing, He said that I misunderstood his proposal, what he says is using five double 200uF+200uF cans (400 uF each cap), which are rated for 500V (not 200 as I misunderstood) to get the 2000uF needed for C2, ...

It did not last long….
Just a couple days back I was thinking that I will live with my current lower bass for a while and now I feel that I will not. I do not feel that my current ULF is wrong. In fact I feel that it is truly superb but I wou...

Ok, what would believe…. but I am in needs to get another phonostage. Te older I become the lazier I become and there is no way I would switch those cables form tonearms again. Also, each time I switch the cables the unused cables drops behind my rac...

And The first thing I did was I grabbed the multimeter and started measuring what JJ suggested. I think we're on the trail of "something". I discharged all the capacitors in the amplifier and with the amplifier turned off, when I put the red tip ...

[quote user="jessie.dazzle"] If I get you correctly, the graph should display a range of around 12dB from top to bottom, in .5dB steps... Yes? [/quote]Yes, it would do, you might go for high or lower resolution, and there are no rules in it. You shel...

[quote user="cv"] What I was trying to say is that as this is what you use to assess the results of your playback experimentation, this is what you might cover first. Places everything else in context. [/quote]

[quote user="tuga"]Hello,
I have owned a TDA1543 based Kusonoki style (passive I/V, digital filterless, non oversampling) DAC for almost two years.
You can have a look at the measurements here.
I find that this kind of implementation (Kusonoki...

I got it!
I realty have got it this time and it is exactly what I was craving for and shooting for. I converted both channels for 18db/octave on tweeter and recalibrated the whole Macondo, in a slightly different manner...

Playing recently with setting up the new 6-ch Milq I again got an interesting feeling about my Fundamentals Channel. The in Injection Channel partially overrides some benefit of the Fundamentals Channel and I have a partial feeling that it would be p...

I'm wondering if Romy experimented with the feedback resistor quality. His ingenious contribution to the design was to use the purest caps possible as in the feedback loop every imperfection gets amplified. So the next logical step after caps wou...

Jessie,
I was trying to evaluate the gain of my amplification in respect to larger room and again was thinking about your case. I think something that you do it not correct. You are complaining that you have not enough gain in upperbass, but I...

This thread has been pretty interesting overall. I've read most of it and would at least like to provide some feedback on the technical side of designing with the 45 and 2A3 DHTs... at least from my personal experience. A few years back I decid...

I mentioned earlier that this is my first electtrical device that I build. Realizing that it could be dangerous to my health and even my life ... I planned and soldered all the parts for a couple of months. I know every connection and ever...

Well, I was there, which is more than The Cat can say. In fact, The Cat never heard a complete WE system first hand, so I'll have to take that into advisement when the expected foaming-at-the-whiskers rant.I always wonder why people would giv...

I have experimented with SS/SET and now DSEP for ceramic magnet horn drivers. I will agree that ceramic drivers with SETs that I have heard being suboptimal, but after a year of DSEP, at least for my use case, I am quite content. I cannot explain it ...

Dealing more with Sun Audio SV-2A3 kit it amassed me how bad the kit was. The guys made very cheap, in fact I hardly believe that this company has anything to do with Japan – it looks more like K-Mart level of amplifier. I heard a number of very posi...

Gintaras, yes, the 10.5mA was a bit too little for gas
tube, 21mA. If you look at the stability of voltage regulation graph for these
tubes then you will see an ark with 15-20ma being atop.
I do not understand why you keep asking me R13

As I told before I picked recently a new interesting DAC and I got for it some AES/EBU cables. That made me to make the same Bidat vs. Lavry experiments only to use the AES/EBU interface with Lavry Gold. During those experiments I did not use S...

Thanks for the detailed answers. I will explain my setup.You are right about the dipole bass correction instead of the injection channel. Since I am waiting for both a subwoofer and the Fane Studio 8M and their horn, I am using the 12" as a b...
