Marshall Cab Sim

If I remember correctly this circuit is taken from original Marshall amp which has speaker simulator built in and it should provide frequency response similar to Marshall 4×12″ cab. It can be handy for direct amp-less recording or used in conjunction with Line Out from amp. Below is frequency plot of this circuit.

    Hello!
    I’m interested in this DIY cab simulator. But I can’t see any visible schematic, circuit or component list. Could you help me?
    Thank you for your collaboration.

    Capacitors in pF range are mica or ceramic, nF range are box film caps and uF range are electrolytics
