Just checked the Calex website. They don't make a 6V DC supply per se, but they do make 5, 10, and 12V ones. You don't say how much current you need for your motor, and that may be a shortcoming with respect to Calex. They make a 1A, 5V supply and a 400mA, 12V supply. You could make a voltage divider network to change 12V to 6V, but the current may be a deal-killer (if you need more than 400mA.). Instead, check out regulated 6V supplies meant for vacuum tube filaments. Several companies sell them in ready to use form. IMO, it would be silly to pay $1000 for the supply you mentioned. Also, what's wrong with a 6V car battery? Old cars used 6V instead of 12V electrical systems. Many companies make very high quality 6V car batteries for auto and marine use (check out "Optima"; it's the best). That's your cheapest and best solution. If you bypass the battery output with a lot of capacitance, it makes a nice difference. I run my cdp with a 12V car batt; it's attached to a trickle charger which is charging when the batt is not in use.
Custom Power Supply for 6v DC Motor
I'm trying to find a more substantial power supply to replace the wall wart that came with my Amazon Model Two. I need a 6v ac/dc converter. Anyone know a source for something like this? Or someone that could make me one? I can get a Black Lightening from Red Wine Audio but that's $1000 plus. I'd be willing to spend half that.

Acopian is a specialist in quality power supplies. They have a lot of choices. An appropriate Gold Box model would very probably cost less than you say you're ready to pay. |
tobias, Those are very nice supplies. They make AC input 6VDC supplies with up to 40A output! OP should look to find power requirements of his motor (will be in watts, W). Then figure out the current demand by dividing the power in W by 6. Based on P (in Watts) = current (in Amperes) X voltage. Take that number and add a safety margin of 1.5X or 2X, and you are good to go with one of those Acopian supplies. Or a battery. |
My very humble experience in upgrading power supplies and connections suggests that it would be wrong to neglect the quality of the cable which connects the PS to the equipment. For example, a shielded and (perhaps I should blush here, it does seem like overkill) cryo-treated cable sounded as clean as a 12V battery when used to connect an overbuilt regulated supply to my Apogee Mini-DAC. In comparison, a cable made up of scrap Radio Shack 18ga speaker wire and the same connectors sounded gritty and edgy. |
