I want to know if there is a simple way to rig up my Technics SA-203 receiver so that I can hook up speakers with RCA cables rather than the raw-wire standard connections. I've attached a photo of the back of the amp for reference.
Thanks in advance for any help.
You don’t want to use RCA-terminated cables for speaker-level connections -- those are for connecting line-level components to your receiver, such as a CD player or a tuner. There are, however, alternatives to bare wire for connecting your speakers.
I looked at the picture you sent and from what I can tell the speaker connectors on the back have holes that can probably accommodate banana-plug connectors. I prefer good-quality banana plugs over all other connection types because they’re easy to connect and they don’t slip loose. If those holes won't accomodate bananas, I’m pretty sure that if you unscrew the connector you’ll see a hole in the binding post that can either accommodate a banana plug or a pin connector, which is another way to terminate speaker wires. If the binding posts won’t allow for pins or bananas (I’m pretty sure they will allow for at least one of the types), them I’m sure they’ll allow spade lugs, which are placed around the post and clamped down by screwing the plastic part tight.
