Post Subject: Plans with PurePower for this week.Posted by Romy the Cat on: 1/23/2011

I am not sure how much time I will have coming week to experiment with audio but if I do then here is what I would like mote have done.

This week PurePower will return my second PP2000, presumably fixed. If this new unit sounds identical to my current one then I am planning to load one of them with more caps. I bought Cornell Dubilier, 80VDC 15000UF and planning to use 6 of them per battery. They caps are small and have ESR .017 per unit. So, 6 of them will give me 90.000uF and ESR at .000007R.

I do have a feeling that larger caps might be effective to make PP2000 to be more input electricity independent. I also have a feeling that PurePower reduce in new unit the battery bypass that they have on board. My former unit when I disconnect battery and disconnect power cord was able to start and to “work” for 1-2 second. Obviously it was from the bypass battery that holds some charge. The new unit with no battery or power has ultra short pulse and it is it. So, ether the capacitance of the battery’s bypass cap in new unit is much lower or they use wrong cap that has to high impedance and too high leakage ands it very fast discard itself. I do not think they bleed it intentionally.
