My circuit is based on RH84 but not exactly the same.
I posted the schematic in an earlier thread. Here it is again.
Each 12AT7 triode section has a plate resistor which was connected with a short piece of wire, then a single wire going to B+.
I cut the connection wire and used separate wires from each plate resistor to the B+ node.
Each channel has its own feedback resistor.
