Sansui 9090 Replacing Speaker Terminals with Banana Jacks

- This video outlines the steps taken to install dual banana jacks* on the receiver. This process did not modify the unit in any way that wasn't 100% reversible.
*Banana Jacks sound like a breakfast cereal, doesn't it? I can imagine the ingredient list:
Air, sugar, artificial banana flavoring. :)
Thanks for making a video for this modification! Since I also produce some content, I know that it about doubles the actual work time just to record it, and then take that doubled time and add it to the video production work, so, 30 mins of work becomes 2+ hours of time.
It does add time, but believe it or not I've actually seen things in video I shot that I didn't see when it was right in front of me! But I've also gotten some really good advice and tips from viewers and guys like you who have other channels. That makes it worth it right there.
Looks good Ray, nice work
Technically, these aren't merely banana jacks, they're 5 way binding posts, which usually have 4 or 5 different ways in which wires can be attached to them.
Hello Ray , I think this Sansui model is in love with you and ask for attention hahaha !
Old love never relaly dies 😊
Thank you for the upload , I have several vintage amplifiers that do need new speaker modern posts ,it's not always as evident to find the right physical solutions ........and to find the less expensive non magnetic connectors.
Have a nice day Ray
i've been doing the hemostat trick for awhile and being as i use cheapo hemos, they bend and i bend them back and over time, they break. there is a trick however: wrap a rubberband ,fairly tightly, around the jaws then open them up, grab the nut and the rubberband holds the jaws in place, holding the nut in place. i never keep rubberbands around so i just bend , break, buy new.
Yeah, the first time my friend showed me this I was afraid it would ruin the hemostats, but that's never happened. I can't remember where I bought them, but I guess I've just been lucky.
@@raygianelli3612, One of my pairs of needlenose pliers has elastic bands wrapped around them on the jaws side so they will stay closed for holding parts, similar to what was recommended here with the hemostats. Small needle knows like we use for electronics work often has a Spring that forces them open when you let go of the handle and so I usually remove that Spring and then I have the option of adding the rubber band to make them stay closed which is usually more helpful for this type of work. Small wire cutters, on the other hand, are most useful when they do have a built-in spring to make them stay open until you manually squeeze the jaws shut. Rarely can we find tools that are set up exactly the way we want them and often find modifications necessary to make them more convenient to use.
In my opinion it looks better with the banana jacks !
Hi, like the channel. Just a quick question. I tested my speaker outputs, and the two righthand sides read 18.7 millivolts, and the lefthand side reads 14.8. Is this normal 🤔
I have a musical fidelity A3.2 cr Dual mono Power amplifier
Mike, that's just DC offset. Some amps have an adjustment for this, some don't. While the ideal is zero, I wouldn't lose any sleep over the levels you quote.
I have a video on bias and offset, which explains what they are.
"solder two wires together and you forgot to put the heatshrink on".....Ray, I felt personally attacked by that comment! haha
It's nice to know I'm not alone. 😁
Hello, I follow your channel very carefully, they are a great help for those of us who are not technical, they are a great help, I am very pleased to share your great knowledge, detail and patience with us.
It's only fair, as it was shared with me. Perhaps someday you will share it with others. That's how we keep this skill set alive.
Another great video Ray. I appreciate your attention to detail and preservation to the equipment. In line with the hemostat trick my previous job before retirement had a way of remembering things. This trick was Red, Ring, Right and Ridge. The banana jacks just stood out to me after working 38 years with a large communications company.
Ha, I was in the same sinking ship you were, for 41+ years. I am still trying to transition back to the resistor color code from PIC wiring, but I am slowly doing it, lol. Not too much besides an old 76C tone box had binding posts, some, but not too much test equipment I used had banana jacks/plugs, but quality audio speakers and amplifiers from the mid 70's and up seemed to use them.
Thanks Mike.
It used to be all about tip and ring where I work, now it's mostly fiber.
@@raygianelli3612 And.. scoping ad cleaning any 10G and up fiber connections, something I found that most rarely ever did.
