Up for sale is a fully restored Trio KA-8100 integrated amplifier. Trio was the parent company of Kenwood before they split up in the 80s and then the Kenwood name was used for USA sales, while the Trio name for overseas sales. This is a 100VAC Japanese model whose USA equivalent is the Kenwood KA-601, except the Trio also includes a MC (moving coil) phono input. Price includes a 1000W step down transformer, which converts 120VAC to 100VAC to correctly power the amplifier.

So what does fully restored mean? It means that:
* ALL resistors were upgraded to metal film types
* ALL capacitors (electrolytic, ceramic and film) were upgraded >>> main filter caps increased from 6,800uF to 10,000uF ea.
* ALL diodes were replaced and upgraded
* New protection relay
* Most all transistors were replaced except for outputs, JFETs and dual transistors
* A fuse holder (and new fuse) was added to replace soldered in fuse
* All controls were given the prerequisite Deoxit treatment
* Cover finished in Krylon Fusion Hammered Black paint

If you can find a better sounding Trio KA-8100 (Japanese 100V Kenwood KA-601), buy it...but you won't find one.
