.......no problem with turning off just your tube pre and leaving the SS gear powered up. In fact, if you had a source playing, an "off" pre-amp would prevent a signal from reaching the amp and speakers. I have a similar setup, but can leave my tube pre-amp in standby-- in fact I leave everything in standby except SS amp, and only turn that off 'cuz it hums sometimes. Cheers. Craig
mixing tubes and transistors
I'm considering getting a tube preamp in an otherwise all solid state system. The solid state gear is designed to be left on all the time. The tubes in the preamp wouldn't last very long if left powered up all the time. Here's my dilemma: the power amp owner's manual says to power down the components in sequence from the speakers "backward" to the source. The preamp is in the middle of this chain. If I turn off the preamp (to extend tube life) while leaving the amp and sources on (to keep the transistors thermo-electrically stable) am I creating any electrical hazards for my equipment? Please advise, and thanks.
