Koetsu Black

The typical output is 0.4mV and loading should be 30 Ohms for a tube section and between 10-50 Ohms for a transistor section. Tracking force should be 2.0-2.2g and the VTA is correct with the body parallel to the record.

Happy listening

Loading is 100 ohm and this number is constant regardless of tube or solid state. However if you're using step up transformer, than the transformer should be 10-20 ohm input impedance. Output is 0.5mV. VTA parallel to slightly lower tonearm (1-3 degree down).

Tracks 1.9-2.1g. Start with 2.0g.

I am qualified to comment. Owned Black, Red, Rosewood Sig, Urushi, and Onyx. Used with tube ARC Ph3, various solid state, various transformers.

your both right,ive had 5 koetsu's( 2 blacks & 3 rosewoods)& they have all had different outputs from each other,100 ohms is the load,i know 2.2 grams is too heavy,but i swear they sound better there.& that 1-3 degrees down is magical
