Making phono resistance plugs

@lalitk 

What else I can do to achieve some consistency in load settings? Or is that simply not possible with my current phonostage?

Please read the post from @tvad , set load to 47kΩ on your phono stage, use a rca Y adaptor and custom loading plug (for example, you can use 60Ω, 75Ω, 150Ω resistors) to get optimal sound.
