5f1 damaged??

[old_picker]

i know this is really pretty lame newbie issue but hoping someone can give a little advice on this one.

I ran a champ [5f1 circuit] for a couple minutes on standby and then switched to full power with no speaker load. foolishly i forgot to connect the speakerbox.

i connected a speaker after powering down then standby> power on and it seems to be running ok

my question is whether under this scenario, is any damage likely to have occurred? and if so what component would be involved and what signs should i be watching for ?? ie more hum? overheating$, tubes blowing?, blowing fuses?

thanks

If its working normally you probably didn't do it any harm. If you're worried, then keep an eye on it next time you play it for a while for any smoke or funny noises.

I've done that a few times also, with no ill effects, but like you, I caught it within a few minutes. Some folks have a resistor across the output jack to prevent damage, but I don't remember what value they use.
