can a RCA switch box be made for 2 pre amps?

Is it possible to buy or make a small RCA switch box so I can choose to use my tube pre for music and also my SS theater processor when watching tv/movies? I would really just need to be able to route the 2 sources into one hopefully small box and switch desired sources, I am on a fixed income so cheap options are a plus, I need this because of a disability wich makes it hard to manually swith wires and as of now I route the tube through a multi channel bypass on the theater pro, wich probably degrades the better tube signal. thanks

Of course, the better route would be to route the L/R outputs of the processor through a HT bypass on the tube preamp but, if that is impossible, a simple input switch would work.

2 pairs of RCA inputs, one pair of RCA outputs and a 2pole/2throw switch (switches the HOT from each while leaving all the grounds connected). I would suggest a shorting switch if you ever want to use it with the power amp on.

You might even consider a 4pole/2throw shorting switch (switches HOTs and grounds) to completely isolate the two preamps.
