My Yamaha A-1 from the late 70's is currently hooked up to my panasonic dvr doing dual duty playing cd's and movie sound playback.
The amp is rated at 70w rms per channel according to the manual, so theoretically i assumed it would consume roughly around 140w of power.
Now the interesting thing I tried today just out of curiosity, I plugged the A-1 into the power monitoring meter and it reads power consumption as being ONLY 24-26w while playing a cd or watching a movie.
Mine is a 240v version being in Australia.
This has got me surprised and confused. Is the power consumption right or is there something wrong with my unit.
If it is what it is, then this is one very efficient amplifier. As soon as I switch it off, power consumption drops to zero.
Even my Sony LED TV, which is the latest model consumes 19w when switched off and on standby and between 48-54w when on which is also way below sony's rated power consumption of 120w for this particular model.
As far as I can tell, the A-1 is playing perfectly as it has always done and have not noticed any degradation in sound.
The only degradation I have noticed is my ears as I get older. Bugger!
I would like to get other peoples opinion on the power consumption and in particular the A-1 if anyone has a power meter they can test on this amp just for comparison.
