Ming Da MC7R Vacuum Tube Preamplifier
I bought this preamp to elevate my listening experience in conjunction with a nice Quad power amplifier (transistors). By using old Mullard valves, I got a richer and warmer sound. However, I am selling this unit with the standard Chinese tubes. It presents some signs of usage, please study the photos. This is a private sale; no warranty, no returns, no swaps, no scammers! Shipping is available at an agreed cost.
