KEL84 XL Integrated final testing problem

[misterc6]

I'm in the final stage of testing my self-build KEL84 XL. I’m getting continuity from the first five roundels on each channel back to the potentiometer. The circuit diagram of the relay board is not included in the information pack so I’m not sure what should be happening with the ‘Tape Out’ roundels, surely they must be connected to the buffer resistors on the relay board and have no continuity to the potentiometer. Is that correct?
