This Jolida tube phono preamplifier is considered a reference in the audio fans worlds. A unique feature is the possibility to tune it, done for this one by the reference professional in France. I join the bill at my name when i purchased it second hand 4 years ago. There are marks in the aluminum front plate (received it like that) that do not affect its great sound. I needed to buy a Nagra phono amplifier to get something better. Now that I am broke (!), I am selling my other gear. Works perfectly for MM and MC cartridges. All settings are described in the attached copy of the manual. Even though it is working perfectly and being shipped in its original double boxing, I cannot guarantee flawless functioning after shipment. Best would be to pick it up. Good luck bidding.
