I don’t see a problem. The clearaudio price is beyond ridiculous. Get a 12V Optima car battery and the Optima “smart” trickle charger, for maybe $200 or so, and be happy. Best to shut down the charger when you’re running the TT, and for an extra tweak, bypass the battery with a couple of thousand uF of capacitance. This reduces the output impedance.
Possibly Dumb Question re:Battery as a power supply
I have bought a new Clearaudio Performance DC Wood turntable. I plan to drive to the dealer in Atlanta and pick it up next Wednesday. I have seen the wall wart power supply which comes with the TT, and it is not a pretty sight. Clearaudio sells an upgraded 12V battery and charger supply for "only" $1,200.00. I don't wish to present myself as a parsimonious individual, but $1,200.00 seems a bit steep to me. I am wondering what problems would ensue if I bought a moderately sized (say 25 or 30 lbs.) , sealed, lead acid, 12V rechargeable battery; attached the proper wires to connect to the TT, and used it as a power supply. When the battery runs down I could just take it to my workshop and use my electronic, automatic battery charger I use to recharge car, truck and tractor batteries to bring it back to full power. As little current as the TT uses this shouldn't be too frequent a chore. It is just a possibility, but if it is feasible I might try it. I would really appreciate any and all comments, criticism or warnings.

Some very good sounding components use battery power. For instance the streamer I use is a Aurender W20SE ($22K) uses a battery to power it. Wall warts typically are well worth replacing. I replaced the internal power supply in my $9K Sim Moon DAC with a dedicated Sim Moon $8K external power supply… it was worth it! Typically external power supplies for turntables are highly refined and regulated. But, why not, try it. I bet it sounds better than the wall wart! You could always get a trickle charger to keep the battery up to top performance in between uses… I assume you are not married? |
