I just picked up a Technics SLB-20. The level is very low on my current receiver; however, I understand that it is because the receiver does not have a built in preamp to bring the level up. I do have another receiver elsewhere that says I will need a phono pre-amp if the record player uses a moving coil cartridge. I cannot find anywhere what type of cartirdge the SLB-20 uses. The closest thing I found was that it uses a VM cartridge, and I do not know what VM stands for. Can someone please help me out? Thanks so much.
