Yes, you are right, the voltage divider from 6.3V across 47K and 10K resistors shall give not 0.9V but 1.1V. However, the numbers that are in circuit are not something that I saw in my dreams but the actual numbers that I measured. I might presume th...

I don't have a scope, so can't measure the output of my particular unit. However, if I were to guess, I would say that my unit probably falls alongside your #2 unit. When run from AC, the bass disappears and the sound becomes bright and edgy, to the ...

[quote user="joaco"]hmmm sorry Romy for the lost of your pp2000 ....I would like to share one opinion from a technician that lives in Japan and lived in Chile . We were discussing the issues of electricity and he said "Lines in Chile are poor quialit...

Yes. Their is a direct correlation between surge current and dielectric materials dielectric constant. The voltages in question are high enough to use a thick dielectric material and just as with the effective resistance of the capacitor, there is a ...

I got a contact from PurePower this morning and they requested some times to look into what is going on. It was not exactly pleasant that they took my behavior as my personal attack against them – it was absolutely not my intention and I have no pers...

Romy,I agree with the very nice summary you have made of the situation. You remember that I struggled for a couple years to get PurePower to return my PP2000 which had gone for repairs, but ultimately they replaced it with a PP3000+. I just have to ...
|

It is true never send your unit back for repair to Pure Power. Mine was never returned and my money was never refunded.I agree the sound of the battery was the most pleasant and quiet when I had my PP2000. It is an approach to the problem, but it is ...

It is detailed elsewhere on the website, but when I sent my PP2000 to be repaired, I received endless promises. It turned out the company was going through a major crisis with a Chinese manufacturer and distributor trying to usurp the brand. They eve...

Romy , you are right , pure power affects on wall AC quality, when a pp3000 is connected to wall ac (the TV not connected to PP3000) then the picture quality of my TV decrease. allways I use only one pure power 3000 and other pure powers are disconne...

Adrian, I have alternately revelled in and anguished over this for some time now, the lynch pin for me being the electricity. Yes, I can generally hear any change I make to the system, but it is consistently the quality of the electricity that ...

Thanks, Bill, I do not need it yet. I estimate that I am a good 2-5 weeks away from the time what I might just stat play with my playback at any more or less refined level. Also, I would like as well you to compare your PP2000 with mine, not that I s...

To recap what I have said before, the issue is bad electricity, which makes your stereo much like aliving thing with tempermental moods. The same way that a steak can change from a sizzling, juicy tender delight to a cold greasy lump after being chil...

I am talking about the fans and the capacitors. I have a PP2000 and the more you load it, the more the capacitors "whine".Nothing from the speakers themselves. It is a pity that cooling is not passive taking into account the efficiency announced. I g...

I do not know, Meiko41. I am not a speak-person for PP2000 and I am in very same boat as you are. They told me that they have a modification that would make the fan more silent and they promised to send it to me… a year ago. Frankly I did not insist ...

[quote user="nl"] I have used Russian high-gm tubes like 6C45 in amps before, including single-stage designs very much like Romy's single-stage Milq. These have many attractions. However, in my experience it just didn't have the tone. Jim de Kort of ...

A few words before I lay down the facts. Over the last week I got a number of signals from PurePower that I shall not defame their products. Their marketing director Bob Rapoport – a certifiable idiots – informed me that...

Another thing to think about along with larger batteries for the PP is the charging process, which needs to be "shaped" to make best use of the particular battery or batteries, including maximizing battery life. Also, if the stock PP2000 uses se...

[quote user="thegooddoctor"]This looks to be extremely well made with the recharging, battery, and regeneration portions separated into three discrete chassis with industrial-type umbilicals/connectors between each. I have seen such a configurati...

[quote user="Romy the Cat"]I was thinking about this: how come that driving 6C33C (in fact driving anything one can imagine) the 6E5P was very fine but driving 2A3 it was dull like hell. I opened the amp and tested all – everything was perfect but th...

I got home today, power up the payback and played some bootlegs of Australian festivals that Kostas Metaxas sent me another day. I paid attention that the sound was strange it was too hard atop. That was something new. I put in my player the CDs...

It is confusing, but the NEUTRAL is not only "referenced to ground", but in properly-designed components it is THE reference to ground. Too bad most commercial hi-fi gear splits any and all grounding, at any point in any circuit, between the ne...

Thanks for the info Meiko41 !At what load (the percentage on the display) does the noise from the capacitors becomes annoying ? Do the fans stay always on or they kick in when you reach certain temperature ? I gues...

It was as a year with a 2 major of audio events: New listening room, New Midbass horns, New ULF channel. It took almost 6 months to get any more or less reasonable sound in my new listening room, not that I was working so long on the room but rather ...
