Thanks for your reply. If you do turn up the manual (electronic or otherwise) please let me know. Schematics may be useful, too, as it might need repair (volume when using preamp out into power amp is way below what it should be. If I use the internal power amp and the speaker outs, it's quite loud, so not sure what's up). I will pm you my email if you wouldn't mind sending along the schematic. Thanks!
