That 70W is only for standby. It can draw much more under demand.
My 100W, class A, SS draws 500W at idle that just goes to heat.

Tube amps and power consumption
A few days ago, I almost bought a Jadis Orchestra, pretty confident that it was among the best tube integrated I could get. Then, I read the specs and I found out its power consumption was 300 watts. That's a lot compared to my actual amp, a SS 100 watts per chanel which uses only 70 watts. My amp is on all day long so I figured that the Jadis consumption was excessive. Do ALL tube amps have such a power consumption?
