Domesday Duplicator Gain Settings for specific laserdisc players

For the Domesday Duplicator gain setting, here are some values I've discovered through trial and error.

See: https://www.domesday86.com/?page_id=2233#Gain_configuration

NOTE: The first number is switch 1 (so 1000 means switch 1 is on, the rest are off)

LD-V4300D:
LD-V8000:

    1000    (8.5 gain)

 

CLD-V2600:

  • 0100 (6 gain if the disc isn't full length; will cause slight clipping at the end of a full length disc) 
  • 0010 (4.4 gain if the disc is full length) 

Resistor/Gain

Switch 1: R406, 1.5k
Switch 2: R407, 1k
Switch 3: R408, 680
Switch 4: R409, 560

Some values just for clarity:
