how to hook my onkyo stereo preamplifier to my RCA stereo receiver?

 

[anwaypasible]

we need model numbers to explore the situation ourselves.

or

what inputs and outputs does the preamp have?
and
what inputs and outputs does the RCA receiver have?

having the model numbers is usually best because sometimes we can take apart a proprietary socket and route the pins 'alternatively'

you just hook the preamp output, with RCA cables, to the AUX input on the RCA reciever
