Vintage RFZ Preamp Racking
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!!
