Hi all, I've just acquired a Beolit 600 type TR52 and see from the user guide that the 3.5mm tape recorder output could be rewired by a dealer as a phonograph input for crystal or ceramic cartridges. Firstly does anyone know what connections need adjusting, and secondly would this work as a line input? Also when I increase the bass level it seems to lose all bass when above 3/4 of the switch – what would be the likely cause of this? Thanks! Login to view image
