Vintage RFZ Preamp Racking

Posted by in equipment, KORN HARDCORE CUSTOMS, mods & repairs, News, rent studio

Those great sounding 70’s preamps from the former GDR broadcasting with discrete design and transformers were found on a local fleamarket.  Now they needed recycled wooden housings (dia boxes) powersupplies und XLR inputs/outputs. Not the most versatile preamp (no low cut,48V) but perfect for dynamic mics. Really pleased with the coloured tone and the huge amplification of 70dB!! V740 schematic:
