I was wondering if anyone out there can help me. I have a pair of Cerwin Vega 12t (not 12tr) speakers. One of the tweeters is not getting a signal from the crossover (I know this because I swapped tweeters and they both work fine in the other speaker.) Does anyone know where I could find a replacement crossover? It is marked 2046 on the circuit board. Or does anyone have schematics so I could possibly diagnose it. I have sprayed contact cleaner into the pot. adjuster hoping that would solve my problem, it didn't. Help
