Technics SA-T670 Power Test     March 2013   Filed Under: Cool Stuff

These amps were a NZ only model and specs are elusive. There has been some controversy about the real power output so here's the real oil.

Here it is, sweet looking beast.

48.1 volts on the rails, good raw material.

Nice Dale 8 ohm 1% load resistors - these will get a bit hot...

There we go - 40V peak at clipping under load ((40 X .707)^2)/8 =99.96 watts RMS into 8 ohms both channels driven.

I got an unusual request from a customer wanting a turntable to turn into a clock. Scott chose a Bang and Olufsen Beogram 1200 I had been storing for parts. He sent me a picture of the finished result - awesome!
