[AMPS] 572B Selection

[Steve Lawrence]

My workhorse SB200 has less P.O. on the higher bands than when the tubes
were new. The tubes are Centron. RFParts lists:

                  Each      Matched Pair
Svetlana          $55          $120
Taylor            $40          $ 90
Centron           $70          $150

I've never heard of taylor. Where are Centron's made?

I have not worried about matched pairs in the past and haven't noticed that
it mattered for this Amp.

Which is the brand to buy? Other sources?

Comments appreciated. 73, Steve WB6RSE
