Hello,
Someone brought a dead RCF NXL24-A in for repair. It's from a school, they said that someone probably either dropped it, plugged in a wrong input or overloaded it (unlikely since it probably has pretty good protection) and now the tweeter works fine but the woofers do nothing. I've already measured the LF drivers and they measure good. No visual damage on the amplifier board, output devices measure good, all connections were okay. Anybody have a service manual or schematic for it? Would be good to have one to dig deeper.
Looking at the board, It could easily be that it was dropped or bumped or something and now there's a bad solder joint somewhere, the board is really thin and the soldering quality is pretty crap
