Thanks, Stan. I just checked and sure enough my "Phono Equalization Kit" was made by DB Systems.

It provides polystyrene capacitors, mounted on rca plugs, with values of 100, 150, 200, 300, and 400 pf; 100 ohm 1% metal film resistors mounted on rca plugs for use with MC's; a pair of spare plugs; and a pair of y-adapters. The part number of the kit was DBP-6.

The instructions also made reference to a DBP-11 "Capacitance Loading Switchbox," which could accept inputs from two turntables, provide independently selectable capacitive loading of each cartridge, and allow the user to select which cartridge's outputs are routed to the phono stage.
