Matching Tubes

When matching tubes (where you need 2 or more tubes per channel)  - is it OK that the Left and Right channel tubes are off as long as the pairs on the given channel are exactly the same ?

Had a mix up with TubeDepot...they shipped a matching pair and then another matching pair..... but the two pairs are off.... one set is 46 and another pair is 54....
these are KT150 tubes

thank you !

Can you bias the tubes manually? At what bias does your amp call for?

I just took a look at the AR manual. It states that the tubes should be biased at 65ma. As long as you bias the tubes the same it should not make any difference which tubes you want to use on either of the channels. They should be fine!
