I purchased these from a forum member several years ago. AA crossovers recapped with Solens caps. They sound great. Neutrix connectors were installed by a previous owner. Text for more pictures.

Don't forget about the internal fuses. I know that is not the problem that you are describing, but worth mentioning anyway. There are two external fuses, and two fuses on the chassis that are easily identified with the cover off. All four fuses are rated at 3 amps. I replaced all 4 and have not had a problem since.
