Please look at the schematic attached.

How would you connect this to a set of PP tubes from biasing?

This is an established design and was employed at some stage. Its from an old Steinhart amplifier and is called the ADC system.

I removed it from a Steinhart more than a year ago when I stripped it down. I never noted how it must be connected. Anybody have an idea?
