I have not tried this with my Adcom preamp/tuner ... but you should be able to connect the "tape out jack" on the Adcom to your integrated amplifier (I am doing this currently with a vintage Marantz receiver/NAD integrated amp). The tape out jack passes through "the untouched" signal.
As for the remote, you can typically connect the power cord from any component (i.e.: your tube amplifier) to the Adcom's switched outlet in the back. The plugged in component would need to have a mechanical on/off switch ... and so, the on/off switch would always be pressed in/engaged to "on." You would then use the remote to power up the component & preamp/tuner at the same time. If you are connecting your amp, make sure you drop the preamp/tuner's volume to "0," when you shut off your system ... it will make a nasty thud otherwise. Regards, Rich
