Recharging Nargra Pl-P

I traded a Nagra amp online not knowing too much about it other than the nice look and feel of its interface. Its seems that the row of D batteries are dead. I was wondering how to go about e-charging them. Or do I have to replace them? They appear to be soldered together and possibly heat-shrunk wrapped together.

This is the only reason I can think of why it would not power up, other than some other unforeseen damage, and likewise, a scam. But id like to think not.

Any suggestions?

Also, while i am at it, what sort of cables will I need to get this wired to a turntable and speakers? Any suggested brands or idea of price range? I these get to be too much I may try to sell this item, assuming it works,and at a significant discount. If that's the case, is the serial number shown inside, because there is nothing on the outside.

Thank you all.

I assume to you have the ACtoDC converter also? It's pretty much a automatic process. Those battery's do need to replaced occasionally. (yes they are soldered and shrink wrapped) I'd contact a Nagra dealer or go straight to the factory.

as far as cables just way to many options and price ranges to give you anything other than what I like in my system. We don't know the rest of your system is.

Your PLP, is a fantastic preamp. I'd get the battery's replaced and listen to it before you sell...Nagra gear has a purity on tone that is hard to match or beat...

Jfrech is correct. Before doing anything check if the PL-P works with the AC to DC converter.
I configured my Nagra VPS phono preamp to run on 2 x 12V car batteries (connected in parallel). If space and aesthetics are not an issue, SLA batteries can offer superior performance over D cell batteries. The stock Nagra ACPC-II power supply that came with VPS does an adequate job, but SLA batteries take the VPS to another level of performance. If your Nagra PL-P uses a Lemco power cord like my VPS, then the modd can easily be done yourself. Alternatively, Nagra can sell you a Lemco PC (CHF 130.60) that is un-terminated at the battery end. TAKE CARE ABOUT THE POLARITY!!
Contact me if you like more detail and pictures.

Norm,

A clarification: since the PL-P uses rechargeable batteries, there is a charge monitoring circuit as well as just straight DC input, and therefore the PL-P must use a different supply (the CCC3) vs. the other non-battery Nagra units used the ACPS and ACPS-II power supplies.

I do not have the ACtoDC converter...this may be why the deal went off without a hitch on Craigslist. What does this unit look like? Where can I find one? Will this unit recharge the batteries?

Thank you all for the kind help for an inexpert.

If I cant get it working I may have to let it go and stick to my Harmon Kardon 3270 - a beast, and hardly of the same caliber. But Id love ot hear this Nagra before I decide.
