I have a question about 2 TL12+ and my preamp, how to link two leak mono blocks to one preamp, I have seen it but how does it all plug in by one preamp? I have a Point One Stereo, but the mono block has no switch cable will that work, just didn't want to risk it, so i thought I'll ask. Will it work without needing the switch cable? Just plug it in as it is and turn on the 2 blocks with my preamp to one of the blocks?
