SOLD - Mitchell Cotter MK-2 Step-Up Transformer (set to value P, 2 to 30 ohms) New price is 5. One owner since new, good cosmetic condition . This unit has never been modified. Original silver output wires. Serial # T2-917-911. This unit has been given a thorough listening test on a friend's Linn set-up and it works perfectly. The MK-2 has load impedance jumpers inside, making possible for the user to set its "impedance range" configuration as l, p, s or pp type for optimal cartridge matching. This unit comes in its original "factory setting" as type P. I do not have the connection diagram, but they are available. With proper soldering skills you buyer can change the configuration. These units are relatively rare. Review on Vinyl Engine.
