FOR SALE: Mitchell Cotter MK-2 Step-Up Transformer (set to value P, 2 to 30 ohms)

New Price is $775.  (One sold on ebay in Dec for $940.)

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 Luxman system 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.

I've been looking for the impedance loading/jumpering/wiring diagram for about 15 years. If you know, many of us would be very grateful concerning getting/finding that info.
