Sony TA-N77ES

200 wpc Power Amplifier

This unit has seen some cosmetic wear, but still sounds great. Original box, packing, and manual are not included.

A classic from the mid to late 80's. Made in Japan, this is a 55-pound behemoth with huge analog meters. This TZ-N77ES is a real analog amplifier with a real power switch and turn-on delay relays. When it's off, it's disconnected from the power, and the speaker relays ensure there are never any turn-on or turn-off thumps, even when used with other "sloppy" components. The heatsink stack is internal. No fins are on the outside; the amp is cooled by vertical convection, but can run a bit hot. Has 'crisp' clean power.
