Do the VTL MB450's require matched tubes??

I am going to retube my VTL's and need 16--6550 tubes...do they need to be matched (pairs, quads...whatever)?

It would appear he has them in stock. Check out the NOS Sylvania 6350 for us VTL people. Good Luck Allan

If you bias unmatched tubes to the same grid current, the same grid current will not mean the same offset point on the tube's output characteristics another words for one tube it could be too much and for another is too little...
