Hi Andy,
Why do you want to "replace them" ? Wire does not "go bad"---What "speaker caps" ? What model Phonograph ? Please read "Attn, Newbies" above, in the FAQ's section---

Thw wire has been chewed up and repaired by previous owner. The capacitors I am refering to are the large black things in the center of the photo. I call them capacitors because that is what they look like but the terminology may be wrong. I belive they function as a crossover. Attachments:

Andy,
I dono about what type connector is used on the input cables, on that model ? --post a photo ----but the RCA plugs are re-movable and usable again, unless they are the "molded type". Audio cable (what you are calling "RCA cable", I think)is available at an audio store, or on line. Are the caps marked ? If not, your Service Manual/parts book should tell you what to use ( these seldom fail, too). Ron Rich

Ron, Andy the mech end is just a 7-pin male -same as the tube bases. the cap is just soft plastic and easily removable. If the pins are OK, just cut a good cable with RCA's at each end, strip and solder to the 7-pin plus. I mention a "good" cable as opposed the crap that often comes with consumer-grade DVD players. These have inadequate shielding and hum will result in this hi-gain situation.
FWIW: I've eliminated several of those plugs and just soldered the cable directly to the pins on the back of the socket. The plugs do develop resistance and become another failure point... and you can still unplug from the preamp anyway when removing the mech. It is also a good idea to fashion a clamp to hold the cables coming from the tonearm to the backside of 7-pin socket. Repeated movement of the tonearm eventually breaks the tiny wires at the socket solder lugs.
The side speaker capacitors tend to last a long time due to no having DC on them. You can replace them with "whatever" I don't see any imperative to use non-polarized types.
