Biasing your JOR will be required about once a year accoridng to your usage. KT 90 output tubes are no longer available, so that you will be using kt88's or 6550's (it won't sound the same as with kt90's). It sounds to me as if you chose a YBA Integra DT (a very nice sounding solid state unit, also French, btw), you might be far better off. See if you can't find one to audition. Happy Listening,
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?
