    I just bought a Princeton '65 reissue. I tend to practice on and off during the day and will frequently take a brake to do something else and come back to it. What is your rule of thumb for leaving the amp on? I'm thinking if I know I'm going to be away more than an hour shut if off, if not leave it on, but am curious what other people do.

    Thanks!

    P.S. - I'm not worried about the cost of tubes so that's not a factor.

    I tend to turn them off. But I could understand leaving them on for an hour or less. If not worried about tubes then turn it off.

    I should know this, but it sounds like you are saying that turning it on and off a lot only (or primarily) puts wear on the tubes?

    It's actually better to leave tube amps on than to keep turning them on and off. Heating/ cooling cycles create "wear" on the tubes. Especially if it's cold (like my house gets in the winter). That's what the Standby switch is for...

    Turn the volume down on the amp, put the guitar on the stand and walk away.

    I have heard it can. Just like light bulbs. I would think power tubes and rectifier more so. But operating hot for long periods does too, and resistors and components inside etc are subject to heat degradation also.

    Yeah, I hear you. he did say: "P.S. - I'm not worried about the cost of tubes so that's not a factor." But good comment. :>)

    I side with the belief that people worry way too much about standby switches, and tube longevity. Once it's on, leave it on. Around the house I don't like to leave them on for more than an hour unplayed. At a gig, leave them on until it's time to pack up (so 5 or 6 hours).

    This is a terrific podcast with a guy with a few decades of experience with tube amps. You'll get more insights there too: https://www.fretboardjournal.com/podcasts/the-truth-about-tube-amps-ep.-1/

    I just turn them on when i use them and turn them off when I'm done. Anybody's ever left one on for day's will tell you this.

    I have a standby switch and don't use it. I just turn the guitar volume down. If I'm leaving the room I shut the amp off.

    All I can say is that a local luthier has a vintage AC30 in his workingplace to check the electronics of the instruments he is working on.
    He switches the amp on every morning as soon as he enters his place and switches the amp off when he leaves in the night.
    All he does is turning the volume at zero when he is not using it.

    I play a lot in the evening in between chores, dishes,laundry,house cleaning etc.My home amp does not have a standby, I wanted a coil cable so I bought a Lava coil cable with silent plug on one end.
    I don't like to leave guitar out of case when not playing

    Um, the title of the thread, "For those of you with amps that don't have a stand-by."

    It's what I do also. For years.

    I do the same. For years.

    On big amps, indeed the SBY is useful, not to say compulsory.
    On a single ended 5W amp, I'd say no.
    Once you reach the push-pull category (over 10-15W), I'd say yes.
    That's why I converted the GND SW of my SF PR to SBY.

    But it's me, OK ? :D

    A+!

    It's better for the planet if you turn them off.

    I read that as a stand-by amp, as in a back -up amp. So sue me, lol. I've already spent 10x more energy on this than its importance to me.

    Anyway, my point remains; constant heat/cool cycles can be detrimental. Better to just leave it on if you are going to be playing on and off throughout the day. Better than turning it off/on every 15 minutes.

    On when using it. Off when not. The Stby takes the high voltage off the tubes and a good portion of the circuit. That’s helpful. The voltage and heat wears parts down. My opinion. All electronic components have a life under heat/voltage rating in hours. I build my own circuits and repair my amps etc. I’m not an expert by any stretch but 300-400+voltage is a lot of stress on a circuit. Again this is my opinion.
