    Traynor CYS90 combo ("The Canadian Marshall")


    I turned it (and all pedals) off. I waited a while. Turned it back on. I could swear I'm not getting as much Volume as usual as I'm dialing the MasterVolume.

    It's too early for my heart to sink, not enough coffee.

    I never play this early, maybe my ears haven't woken up?

    Have I fried everything?

    It should be fine. Amps aren’t that fragile. I’ve left mine on or on standby for 10-12 hours and it was never an issue.

    My Twin Reverb pretty much stayed on or on standby for months (maybe even a year), with no ill effects. You may be paranoid.

    The only thing active when an amp is on Standby is the tube heater supply and bias supply. High voltage is turned off.

    You do know all tvs and radios and jukeboxes used to be tube powered? Leaving them pn doesn't hurt them.

    As mentioned, much of tube gear is powered up for days at a time. Think about radio transmitters-maybe running flat out at thousands of volts day after day. Or the PA system at Woodstock-all tube powered and running for days on end. Now think about how much LESS stress there is on everything with just the heaters on-can't hurt the OT, or really anything else. If you had a tube about to go, maybe, but you only hastened its death a tiny bit. Relax and play your guitar!

    Pretty sure space shuttles and other NASA equipment equipped with tubes ran longer than 8 hours at a time too...

    @jblake slept for several months; waking up to a pandemic, riots and an amp that was still turned on.

    Pick up my guitar and play
    Just like yesterday

    Done this before. Hell, I've left amps "ON" overnight. Definitely an "oh, chit" moment when I woke up to see the familiar but concerning glow of a jewel light coming from the amp. No damage done whatsoever.

    You may have coincidentally hit a point of decline in any one of the tubes, but that would most likely be the "most" damage done, and that's a minor thing. Bonus points for cathode bias amps where you can just toss another power tube in, no bias required.

    Not as concerning as the multiple times I've played "mix and match" with a pile of combos and cabs and speakers and you get no sound and it takes you a minute to realize its not because you left your tuning pedal engaged, but because you haven't hooked any speaker load up to the 60s Fender you've been playing silently for a couple minutes. But all those have ended up fine, too. Robust things, I'm sure the Traynor is, too.

    I have all my gear plugged into a power strip. I have a very ADD process for turning everything off, with the power conditioner last.

    I have at one point left the standby on my Reeves Custom 50 overnight, before my process. No damage, but the top was quite hot.

    I'd' imagine letting it cool off would solve any issues.

    Think of all the backline amps used in outdoor festivals. Those things are on or in standby all day long.

    Yeah, obviously doesn’t have kids or a dog. I’m prepared to send mine, no charge...

    It’s most likely fine... if the power transformer couldn’t handle supplying heater voltage for that length of time, you wouldn’t be getting anything at all from it now.

    Left my YBA-1a on for 24 hours the other day. It's still fine. The only thing that'll hurt is your electric bill. ;)

    Consider yourself blessed you did not reach 9 hours. OP have you seen the Lost episode where John Locke does not push the button to reset the timer in the hatch?
