adding a sub to an old LINN system


hi...im an owner of an OLD linn system a pretek and powertek and i would like to add a subwoofer.... the only way i see how is on the back of the poweramp where you daisy chain is a line out to the next power amp.... well its not being used so is it safe to run it direct to a SUB....?
i understand i cant take the lower frequencies out of the tukans this way unless a filter is used but will it sound good and not odd?
also i found another powertek amp second hand and i would like to add it to the rig...would i hear THAT much difference with an amp running the top and an amp running the bottom of the tukans?
thankyou

sir! that is verification that im not mad....i was looking the other night and came to a similar conclusion... well explained...thankyou
You can take a Y-Cable and connect it to the Line Out pair on the Powertek. You would then run an IC or Sub cable from the singleton end of the Y-Cable to the sub.

Alternatively, Audioquest makes an RCA Splitter (1M/2F) that you could connect in pairs to the Line Out on the Pretek. You would then connect a Y-Cable to one of the F-pairs on the splitters and then connect and IC to the singleton end of the Y-Cable, which would then run to the sub.

On newer Linn Preamps, there are 2 Line Out pairs. I have a Wakonda, and have a Y-Cable connected to one of the Line Out pairs which, in turn, is connected to a sub. The other Line Out pair is connected to an LK85 amp.
