IMHO a really bad thing to do. At best it will overload the phono input
and produce distorted sound with too little trebble due to RIAA equlaization.

At worst it will burn it out, and then you won't be able to use it or sell
it to someone else. :-(

Hope not unless the pot is a discrete one and straight after the input.
You'll get a great deal more than 1v P to P out of many CD players.

Well, yeah, I remember that. Inputs were associated with their
equalization schemes; phono (magnetic) inputs were RIAA, and tape head
inputs were NAB equalized. I remember as a kid fooling around with a
Viking tape deck that lacked any electronics; it was made to be plugged
directly into an amplifier (or preamp).

I remember that deck -- and I remember Knight electronics that had a
tape-head input. Tape-head inputs were not common.

I agree many will do the trick just fine, but I've found more than a
few that just would not. Not sure why, either!
