Tube match problems

Hi Everybody

I’m new here and would like to ask for your help. 

I got VTL power amp with 6l6 tubes. They were perfectly match. Unfortunatelly when I was recently moving, took out tubes and forgot to mark tubes against sockets. Now I’ve connected back whole my set up, most luckily tubes in wrong sockets, it doesn’t play as it was. I don’t have tools to check bias and it really difficult to find any place dealing with tube amps in my city. Any ideas to solve this issue, which makes me crazy :(((

Yea, I’m already aware of that. I don’t have a practice, but red lots of articles how to match tube/amp and relevant safety precautions.

Thanks.

The only thing is, the amp doesn’t have bias points from outside and it looks like I have to access there removing bottom panel.

Just another one - If I buy new, matched quad tubes, do I still need to match them with amp?

Hmmm. Ok. 
I hoped I would be able to avoid bias matching. :)

problem is VTL yet didn’t respond me regarding bias parameters of the amp.

my amp is similar to this one and I cannot see test points on it. Does it mean, I have to strip the amp?

Thanks for reply, oddiofyl. 
I have already red this article in VTL’s site - good one. 

Could you check the link that I posted above, photo of the amp similar to mine and could you advise the test point. To be honestly, I’m struggling to recognize it.
