Quad 606 MK2 drawing 55 Watts in standby mode

Hi, I own a Quad 606 MK2 and I measured it's power consumption. It seems that when in standby mode, it already uses 55 Watts, and while playing music it uses between 55 and 60 Watts. I didn't expect it to use such a lot of power being idle. Is this normal? I searched the internet but didn't to manage to find information about idle power consumption...
 
The 606 draws about 60mA in no signal mode.
About 14Watts. See your Service Data manual.

Yes OldDIY is right its a design "feature " of the ( patented ) current dumping design and the ordinary manual also says --"it runs hot " --do not put it near radiators /sunny positions --read up on current dumping.


UK version manual just "splits hairs " in difference to --30-850W by saying 35-750W so "no worries " --as far as I can see .
 
Hi how did you exactly measure power consumption? If you used one of the cheap(er) kWh Schüko devices of years ago then don't be surprised if results are not reliable....

Some of the older ones are notoriously imprecise. Often just ohmic loads could be measured reliably. Point is that many devices are either slightly capacitive or inductive.

With care, you can measure the AC voltage and AC current in the primary circuit with a multimeter (do not forget to switch the type of measurement). Multiply voltage (v) by current (a). You get the power VA.
Excessive consumption may be a sign of malfunction or incorrect settings.
 
Only do this when being experienced in working with mains voltages which in 2021 almost seems a certified way to die with all the possible dangers. Nowadays safety = doing nothing 🙂

Let's not exaggerate but don't do this when not confident or not having the right stuff to measure safely. Simplest is to have a known good kWh/energy meter....
