Replacing Speaker Terminals on Receiver?
msg
Posts: 10,120
Hey guys, any of you replaced/upgraded the speaker terminals on a receiver or integrated before?
Essentially what I'm working with is some older equipment, Marantz, and Onkyo. Both have the spring clip speaker terminals, and I'd like to upgrade them to accept bananas/spades. Is this as simple as desoldering, removing the existing terminal block, fabricating a new one and resoldering the connections?
I say that like it's "plug and play" easy. I do realize that this may require fabrication of a plate of some sort to house the new connectors.
I'm interested to hear what any of you who've done this might have used. I haven't had a close enough look at the equipment yet to see whether these terminal blocks are riveted or screwed in, meaning they can be easily removed, or whether I'll have to do some fancy sheet metal cutting and placement of new material.
I'd also like to do the same on some old speakers. I imagine this is similar?

Speakers are much easier. You run into space problem's on the back of receivers, not only on the outside but also on the inside. Some of the older models might be easier just because there was more blank space on the back sheet metal where you could just drill new holes and make sure to insulate the metal and run new wire to where they joined the board.

It varies a bit from piece to piece, but it always involves cutting away some of the rear metal panel, making a new mounting plate to cover the mess you just made, making a template for the new binding posts, then drilling the holes, etc., etc.
Some stock terminals are PCB mounted, which is a PITA.
Often there is only enough room for one set of binding posts, so you lose the "B" speakers, which is no big deal.

thanks, fine fellows.
I'll pull the covers off and have a look to see what I'd be getting into.
you guys happen to have any photos of projects like this you might have completed?I disabled signatures. -

Binder posts? Try binding posts. He also reversed the +/- post positions.

I had a read over that post. Interesting the reason he gave for the reversal. Is there a standard placement convention for the terminals?I disabled signatures.

Yeah, Those positive terminals so close to each other is scary to say the least! A slip and cabumm! -

On a piece like that where the binding posts are all grouped together, yes. The + always goes on the outside.
