The BC-610 used tube rectifiers in a FW ckt. The "third wire" is the
center tap. The 6KV is the voltage across the complete secondary. It
could handle a 250TH RF stage and a pair of 100TH(L) ? modulators but I
would be leery about using it in a modern SS FWB config.
I built an AM KW with a pair of 250TH's and dual xfmrs salvaged from
BC-610's back in 1957 when I was in the MARS pgm.
