Couple of toob noob questions

[gitbuddy]

Hello everyone, hope this post finds you well

I got my Mark V! Yay! I have a couple of noob questions - hope someone can help please.

Question 1: When I flick from Standby to On, the tubes start to glow with a blue incandesence inside - is this normal? When in Standby, they are just orange.

Question 2: Is it safe to switch between power settings (10, 45, 90) without first going into Standby? I get a loudish pop when I do this and wonder if I am damaging my amp?

Question 3: Related to the above then, are there any things where I should switch to Standby first before changing the settings?

Thanks in advance

1. blue is ok. it's kind of nice some tubes may not have anything other than the orange glow, though.
***red is VERY bad--turn off immediately and replace those tubes (red-plating).

2. loudish pop is expected and explained in the manual. you're basically changing the wiring configurations of the power tubes which will involve application or removal of current/voltage on their terminals.

3. you can put it on standby, but in changing the power settings, i think it's ok.
