I had the DCA-33 and replaced the batteries myself. Open the battery box and get the name and model number of the batteries. Digi Key will be able to supply replacements. Just draw a diagram of how they are wired up. I think it was about $150 to replace them.
N.E.W power amps
I have a N.E.W battery powered amp that needs to have the battery replaced and can not seem to locate any info on the web. If anyone knows any website pertaining to the amp please point me to the right directions or any info on the amp. Thanks in advance.
