Technics SH-305MC Amorphous MC Transformer
This listing is for a super-heavyweight motor with two independently operated toroidal cores ( approximately 4.5 kg ) mounted in a cast iron/aluminum enclosure with heavy shielding.
A step-up transformer for an MC cartridge weighing 4.5 kg is extraordinary in itself.
I'm not saying that heavier is always better, but I do feel that there is some meaning in investing that much material.
Using a groundbreaking, brand-new material—"amorphous"—for the winding core of the step-up transformer...
This masterpiece model embodies the determination of a giant manufacturer, burning with ambition to overturn existing concepts.

★ Condition & Operation
There are some scratches and scuffs, but it is in perfect working order.
There may be other things I've overlooked, but I've included as many images as possible, so please refer to them.
We have performed a demagnetization process to remove unwanted magnetization from the transformer due to aging.
We have performed maintenance, including cleaning up all parts, so the sound quality and other performance aspects are excellent, and it is operating smoothly.
