Default Tech: Seeburg 100JL Amp HFMA1-L6 Resistor Wiring

New guy on the block here, need some help with R48, combo value pale
blue ceramic resistor, mounted on the tube side of the amp between 5U4
and 6L6.

I have a reading on the 2500 but dead on 25K, obtained a 27K
replacement but not sure how to rewire onto the old 3 leg resistor. I
marked my old disconnected wires as follows:

A=1 Ivory color cloth wire, 1Gray wire

B= 2 Red wires

C= 1 Brown wire, 1 bare wire, both go to ground

Thanks guys, really appreciate the help

Try here for a schematic:http://www.verntisdale.com/Seeburgschem.htm

The connections on a HFMA-2 which is similar but uses two separate
resistors is 2500/ohm from 5U4 to junction with the 25K/ohm other side
of which to ground.

Once you download a schematic (from link) you'll have no trouble
tracing the connections from the junction of those two resistors.
