right my RG50TC has been returned but i was just wondering that since am not even sure which end of the standby button had to be pushed in to be in standby mode (excuses coming from the retailer for the state it arrived in and such like so am not atm lol)

When I get the new one ,,, my understanding is that the reason standby is on is to prevent a signal reaching a cold have, would I get the same effect by leaving the guitar unplugged till its warmed up?

Possibly. But on my JCM900, the standby switch is set to standby when it's in the position that would be 'off' on the power button, so that's probably how it is on your Randall, too, since it would make sense. I've never considered having the guitar unplugged as an alternative form of standby, but I'm not sure it would work.

It wouldn't hurt the amp to just turn it on, find out if the amp is in standby or not, and if it's not set it to standby.

Standby means that the preamp has power, but the power amp doesn't. It should be pretty easy to tell if the amp is in standby or not. If the main power switch is off and the amp has power, then it's in standby - you can also look in the back at the tubes. If the preamp (small) tubes are glowing and the power (large) tubes aren't, then it's in standby. There should be some type of indicator light that says it's in standby as well.

If the amp is plugged in and it's not on - just flip the standby switch to the "on" position (obviously the opposite position of what it's in when the amp is completely off) - then wait at least 30 seconds and turn on the main power switch.

And no - leaving your guitar unplugged is definitely not the same as leaving the amp on standby.
