It surprises me if you wish to do away with the battery. Or, perhaps a unit could be offered "less battery", which the purchaser/user could add on his/her own. This would "solve" the logistical problems (and the expense) of shchlepping batteries, a...

I talked for a couple of hours today with a local Solar Power technician, I sort of told him all the gear I have that would need to run on batteries and we got a shaky number; from that number he started calculating a bunch of panels and batteries a...

Hey Bud,Are you saying that the battery materials are less limited in fast dynamic potential energy release than the capacitor materials? I thought batteries had far greater materials limitations compared to capacitors in regards to fast potential re...

And if it is true then the PurePower people did already fuck up their own product. The battery output and output from AC SHALL BE...

Peter, I wish I had more confidence in the amp's power supply as significant proof against the full range of AC power nasties. In fact, I have long had the sense that there is such a thing as "over-regulation" where hi-fi power suppli...

Those recent posts of yours are making me wonder whether my PP2000 unit is really faulty, as PurePower acknowledged on this very forum. After all, you are starting to recognize that PP is sensitive to incoming electricity in your own units. This make...

Strange hums in odd places do often correlate with an internal PP fault. One time before the battery started to fail I got a strange hum through my SACD player. Never happened before. Later after the PP battery was replaced hum disappeared forever....

[quote user="drdna"]I think it has already been stated. Batteries in audio are inherently of limited utility. It is a tendency of audiophiles to dedicate themselves to a single "silver bullet" instead of building the system based on the particular ne...

[quote user="Paul S"]Yes, Bud, I agree that the most common problem for the full-tilt regenerators is that they begin to exhibit various problems in direct proportion to current demands. And this seems to be true even when they are used "below capac...

I meant this scheme. Have the converter start at 105v when turned on and increase to 120v as a nice soft start for the tubes perhaps. Anything is possible with such a set up. I do think that audio is/will benefit greatly from all the technological pu...

"but it highly likely
that PurePower buttery does stay online during the unit run from AC"That's all I am saying also! My idea is ONLY that PP changed the degree to which the equipment *sees* the AC source instead of the battery source. How isolate...
|

Bill, what I find interesting is not the fact that the units vary one from the other in terms of measured performance, or each in its (in)ability to charge its own battery, rather I notice that you seem "happy" with the performance of all the units i...

Romy, you may have seen my meandering post a couple of pages back, where I took a "theoretical" approach to using batteries, and it promptly got out of hand from a purely practical point of view, to say the least. In the case of the "Giant Battery Pa...

I kind of thinking about it and I am not sure that I have an opinion. In the former PP2000 I stunted buttery with over 100K capacitors, presuming that it will driver DCR of buttery lower and therefore improve the day-to-day decoupling of PP2000 from ...
|
|
I guess I needed to say that, outright. Of course I do care about seamless power during line lapses, but not much. I mainly see the battery as a "treated", high-current DC reservoir/source for converting to laundered AC. And, like I have said many...

Decoud, this is a delayed response to your most recent post in this thread (posted 11-14-11): Indeed, why is it "beneficial" to add DC/AC to a battery only to rectify it again? This has never made sense to me, except with my fuzzy "theory" that the P...

For some time I have felt that most audiophile phono stages are over-built, especially those pretending to be thought-out, "no-compromise" designs. Ironically, it seems to me that few (or none) of the "thought-out" designs I have seen and/or heard a...

Rick, sure, working volltage is important. What does your inverter require in the way of current in order to produce it's rated voltage at its rated current? I can remember times when I measured "correct" voltage when the battery was functionally use...

Thanks for the spacing tip. At this point the only part of the inverter attached to the house is through the ground - and that is using a plug for just the ground lead into a close-by receptacle.My main amplifiers (tri-amplified system) are utilizing...
