Dodd PreAmp batteries not charging
I am having a problem with my Dodd preamp. When I set the selector to Bat2 it works fine. When I turn the selector to Bat1, it does not work. The batteries all test about 13.7 volts. I've checked all of the connections and they seem fine. Any help would be much appreciated. They name of someone that works on these would also be appreciated. |
You may try contacting this guy. It seems he’s got experience, regarding the batteries and chargers, that work in your pre: http://www.vinnierossi.com/redwineaudio/ Perhaps one of his, "Ultracapacitor" supplies can work in your application.
