Members Psycho_Angus Posted July 9, 2005 Members Share Posted July 9, 2005 Nope, just means that you've taken a few hours out of the valves life. It's just some voltage and some tubes afterall. Link to comment Share on other sites More sharing options...

Members The*Ataris Posted July 9, 2005 Members Share Posted July 9, 2005 Originally posted by gr8fuldodd cool I thought I'd leave it alone and check it out later but maybe I'll check it out now I just noticed that we have nearly identicle amps (minus the bronco). The power and standby lights on my JMP don't work and I left mine on a whole bunch of times when I first got it. I'd get done playing, flip on standby, and walk off intending to come back in a few minutes. That wasn't as easy as I thought The only way I'd be able to tell it was on later is I'd hear a slight hiss... Link to comment Share on other sites More sharing options...
Members Narcosynthesis Posted July 9, 2005 Members Share Posted July 9, 2005 all it means is you will have a nights less playing time on the valves before they die...it wont harm the amp though, you probably play through the thing for a couple hours at a time, and thats with the full current hitting the valves, in standby they arent getting the full voltage so it wont be as bad studios can leave amps running for days at a time, and they need them sounding perfect the whole time...

Members StratStevo Posted July 9, 2005 Members Share Posted July 9, 2005 Its actually the warming up and cooling down cycle that does the most damage (just like a light bulb), if I turn on a tube amp in the morning and I know that I will be playing later that day I just put it in Standby and leave it on. Your amp is fine Link to comment Share on other sites More sharing options...

Members drano Posted July 10, 2005 Members Share Posted July 10, 2005 Anybody mention NOT TO TURN IT ON AT ALL without some speakers plugged in? That's the accident to watch out for. The transformer will be ruined very quickly without a load. Link to comment Share on other sites More sharing options...
Members pbhtrip Posted July 10, 2005 Members Share Posted July 10, 2005 I left a JCM800 on overnight in a studio once (plugged into a cab of course) and it sounded better the next day. Best mistake I ever made. Peter Link to comment Share on other sites More sharing options...

Best mistake I ever made. Peter just because it is fully warmed up after all the time i always let my amp warm up for 2 minutes (like it says in the marshall book) but after that point, the valves will still be heating up, and they can take quite a while to get up to a steady temperature, so leaving the amp on all night just means it is up to that temp early, and not after half an hour or whatevers playing David Link to comment Share on other sites More sharing options...

Your amp is fine actually, leaving an amp on standby for more than 20 minutes is bad. Link to comment Share on other sites More sharing options...
