Default Aguilar DB-900 question

Dear wise folks,

I collect a schematic from the wide space of the net for the aguilar DB900 active DI-box. Orginally I searched for the VTDB-2B schematic but don´t find it. The Aguilar should be someting "like" the Demeter VTDB-2B.
So far so god:
I do not understand the top triode system (V1B ) of the schematic. It´s looks like a cascode but the decoupling to the transformer is at the CF (V1A) at the buttom. So I think it´s something like a CCS for the V1A system?

Can someone of you clever guys enlight me please???

Thanks a lot
Karsten
