Mesa 2:90 - Tube placement and using channels help needed!

[badguitarist]

Hi guys. Just received my 2:90 today. There were 2 tubes that have been broken. I just pulled out all the tubes before I realised that they're matched pairs. So now I have no idea which is which!! How can I recognise each matched pair of tubes? And where to install them (I mean a matched pair on 2 outter or 2 inner positions or something)? If I want to replace the 2 broken tubes do I have to buy 2 new pairs of matched tubes instead?

I also have an upcoming Triaxis but I only have just 1 speaker from my Mark IV combo (I'm gonna get a cab soon) which means I can only use 1 channel on the 2:90. How can I use just one channel on it?

There's so much confusion to me right now. Any helps would be greatly appreciated!

Not sure what version (red or blue pilot light) you have. Check this link - it should show you the tube layouts of each version. Hope this helps!
