Never misunderestimate the ability of the forum to overthink even the simplest things. Full disclosure: I converted AC to DC battery, did none of that, and it was audibly quite a bit better. Just not that hard. Unless you make it so.
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.

Yeah, I know just what you mean. There's something about Mary. https://www.youtube.com/watch?v=mbFx0CbaIlY |
The smaller battery is the way to go. My Teres turntable was DC powered just like this, with a charger on a relay to automatically disconnect it from AC while playing. It is better that the charger be disconnected. The difference is slight, but there. Mine was an ordinary lead acid motorcycle battery, but that was decades ago. Today I would look for Li-Ion, ideally one small enough to fit right into the unit. |
