Step-up transformer Ortofon ORTOFON TYPE2-15KJ (STM-72) Working condition, used SPU GTE Jorgen Schou JS transformer Step-up transformer for SPU etc. MC cartridge Convenient with on/off switch. When the operation was confirmed, sound could be produced without any problems, but Since this is not a unit that has been recently maintained, we cannot guarantee its operation. This is a valuable STM72, and the cable is the original type from that time. Tags: garrard thorens mcintosh record lp audio jbl tannoy
