Replacing binding posts - anything I should know?

[Cloth Ears]

Hi,

I'm going to replace the lower binding posts that came smashed with my AU-X1 when I purchased it. For $5, you can't expect too much .

I was planning to use insulated items from my local Jaycar. Is there anything I should look for when replacing these speaker posts?

Get good quality posts. Can't speak for what is available down under, but here the local electronics shops pretty much carry crap. Good ones here are $5 or more each. That adds up quick when you need 8 of them. I also prefer insulated ones to non insulated.

I upgraded the binding posts on a G-22000, it required drilling out the square punched holes the originals were mounted in and a lot of heat to solder in the wires. Other than that it was pretty straight forward.

Can you post a pic of the finished project Pete?
I am always interested to see how others tackle common problems!

Had my binding posts replaced on one of my BA 5000's, looks spectacular and now i can use the Ultralink locknut Banana connectors, thumbs up all around, will try to post pics!!!

Here are a few pix of a AU 707 (Japan domestic AU 717) with binding post mod. I would have used some bindiing posts that had black or red washers or knobs but the method is about the same.

Good luck,

Seadzz, It looks like they left very little room to work with so my posts would not have worked for your unit with out some major modification.
I agree, the black and red make it a bit easier and think it looks better.
Her is my G 9000 with the Rat Sahck posts.

Thanks all.

Pete, I'm using item in the attached picture (at least, I hope it's attached). $5 each here too.

Mind you, it's only for show, as I'm quite happy driving one set of speakers through the existing posts.

I too have started work on changing those crummy spring loaded slips on my G9700 thanks to Gamelots' help and direction. I decided to go with the Ratshak posts for $5 a pr as I intend to sell the G9700. For my G901, I will take the plunge and go with Cardas or other high end Gold Plated upscale units.

I will take pix along the way and post them. Maybe some of the Heavy hitters like EW, NosValve, PunkerX or LB Pete could draw up steps and diagrams to help us all out?

Seadzz, the Japanese binding post update used uninsulated posts. With all those posts in such close proximity, something metal touches them, you will short the output. Insulated ones are the way to go to help prevent accidental shorts.

Cloth Ears, those posts are similar to the ones I used. Yours look like they are better. They have set screws to secure the wires. Mine needed to be soldered. I’ll try to get a picture.

Ginovino, Step by step instructions would need to be tailored to specific models. I'm sure that there is enough variation between models that a set of generic instructions just wouldn't cover all the variation.

Replacing the spring loaded terminals is a lot different than just changing out binding posts. But the process is pretty straight forward. You need to remove a pair or set of the old terminals/posts, choose suitable replacements that will fit well in the space and modify the existing opening to accept the new posts. What modifications necessary are dependent on what you took out, how the chassis is set up and what you are putting back in.

I am upgrading mine to some nice gold ones from parts express.I got some nylon bushings from Lowes to use as shielding >I was even able to keep the square holes to put the originals back if needed.1 was missing the black top.I will post some pics in the near future .I have tore the whole amp section down,cleaned ,recapped and upgraded some resistors and added an led power light,even reveneered the end caps.You guys have done some nice jobs on yours.Can anyone say sweeeeet.

LBPete,

Actually I can not take credit for the mod of that AU 707 shpwn in my earlier posts. That handy work was posted right here which is a Japanese site. It is chock full of pictures of many vintage Sansui (and other brands) of amp, tuner and receivers.

You will need a fast connection to visit that site since the pictures are very big files.

Enjoy,

Nice work guys, they all look great!!!!

 

[ginovino]

Very "rich " looking dear Pete!
All the moolah your makinbg selling Sansui AM antenna mounts has paid off!

Maybe the next project should be a solution for the TOTL Receivers, crummy speaker connectors on the 9000- 9700 - 9090 series

What impact if any does changing the binding posts have on the equipments value? I guess if a botch job is done the value goes down but if the job is first rate can the value still go down since the amp is no longer considered "stock"

Thoughts?

I don't know. The G-22 has pretty good binding posts to start with. The biggest reason I changed them is one of the plastic caps was broken. There are advantages to more modern posts especially if you want to use big gauge speaker wire.
