Telefunken Maihak V72 Tube pre-amp in custom rack

Selling this superb Mic Pre-amp.
It is a rare Maihak version of te revered Telefunken V72.
It as been modified for a little gain change with the knob on the module itself. Sonic Messiah built me this super nice rack with Polarity, Phantom power and Gain. 230V only !
The V72 as been completely overhauled and serviced and is good to go into service for the next couple of decades.
