The two outer tubes, left and right of the top of the 'T', are V1a and V1b. The center tube of the top of the 'T' is V2, the top (Voltage-gain-portion) of the cascade. In the M60 3.3, there is no V3; in former versions this was the CCS.

So if you LOVE the sounds of the Sophias (NOT 'sophies'), use your four in the four V1 positions; I'm stickin' with my TSRPs. :-) :-) :-)

Hope this helps.

      - ozziboy uses 'Sophia' and 'sophie' interchangeably. Here's a link... - jeffreybehr 17:50:56 03/27/17 ( 1)
        
        However the vintage European ECC32/33, CV181/CV1988 family of tubes are not real 6SN7 tubes. " - Lew 13:05:51 03/28/17 ( 0)
