Plexi 6V6 V2B ???

[6v6Pin1]

Hello,

I am trying to understand the Plexi 6v6 schematic. I see the signal leaves the V2A plate and goes directly to the V2B grid with no coupling cap. Then the signal is coming out the V2B cathode. What I've seen in other amps is the signal filtered by a coupling cap going in the grid and out the plate.

How/what/why is the function of V2B in this amp?

Thank you!
