As you can see signal is LDR and PRP on this BH

LDR - Light Dependent Resistor? 
PRP - ?
BH - ?

What size AH battery are you using?

I think it's 2AH. I used the bits from a GreenWorks 24V battery. They make a 4AH version but since it was initially an experiment I opted for the cheaper one. Since it works so well I've not bothered to change anything. :)

PRP is Precision Resistive Products - a brand of resistor.

In this case BH is BoozeHound, the low cost phono stage kit from BoozeHound Labs

I see.  Then you just use some LI charger that plugs into the chassis.  Got it.   :thumb:

PRP's are pretty neutral. Nude Visahy's would be better, but they are $12-13 a pop, and I think one other set on the BH can run LDR's. The two that are signal above 20k won't as LDR's breakup in sound on e you start to exceed somewhere around 23k.

The input's are key however. I'd be surprised if any phono stage on the planet wasn't better with LDR input resistors (if it has input resistors). That's partially easy to say since maybe none of them have nude vishays.

I guess $8-9 for LDR isn't much cheaper. Whatever, the results are amazing.

The case is starting to take shape. The front panel is made of MDF and is painted midnight metallic black w/ high gloss clear coat.
The side panels will be of poplar and will be stained dark walnut w/ high gloss clear coat.

Cool! Looking forward to the completed project. FWIW, my little battery powered BHL just keeps working, trouble free.
