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 :(((

You could buy a small multimeter and re-bias the tubes. Look up the proper voltage for your tubes and amp online.
All 6L6's will have the same value for biasing. You don't need to check serial numbers.
But check your tubes to see if they are 6L6, 6L6G, or 6L6GB.
