  • Warm Up Time For Tube Amplifiers

    I found in the past, amplifiers with interstage coupling transformers, for instance the old VAC Rennaissannce and Audio Note amplifiers, took 3-5 hours to,really strut their stuff. I'd say my cjs take a good hour to settle in.

      Myles,
      I won't disagree with it, that is just one man's opinion. I do agree that after some time everything opens up and sounds better.

        Having both tubes and solid state tubes warm up faster I feel. An hour for me either way is min to sound good.
        My Msb dac is on always as is my lampi but the lampi has a solid state recti and shitty new tubes in it until I want to use it. Then I give about 15 mins for actual tube warmup.
        Hours seems high but again it's how we each feel

          My normal routine is to turn on my gear and play music from my server for two hours before I sit down to listen. And it does keep sounding better past the two hour mark at my house.

            I will often sit through the warm up, not listening at full tilt- there is a point usually about 3 or 4 record sides in, when the amps noticeably open up--I usually figure on a 45 minute warm up playing music, but they still get a bit better after they have been running for a while.

              Like others, I'm a 2-hour warm up guy (for electronics) but it also seems that vinyl playback sounds better after a few hours of *playing* records. Warming up the turntable motor for an hour or two and getting the cartridge limbered up for a few sides seem to make a big difference.

                Yes motors and belts needs to warm up, stretch, etc.

                That's what I do as well. Turn the equipment on and starting playing music, knowing that improvements are on the way. .

                    I'll put on some things just want to listen to for the music to warm up the system.

                    Do you leave your amps on too David?

                    Funny thing is that I swear the system sounds even better the few times have left either the tape stage or preamplifier on overnight. But that could also just be day to day variability too.

                      My ML2s have been on 24/7 for most of the time since I bought them years ago, the ML3s I turn off at nights but they're on first thing in the morning. I work from home most days!
