fbm211

I picked these up on audiogon last week and finally got them.Now Im just waiting on some silicoln to make sure their air tight after I install em.
I hope I dont have to remove the PRs to install these since I already did the moretite mod.:eek:

Congratulations on your new binders I'll be replacing mine on 2B's soon, so will be very interested to hear how your change goes. I went with these.

Did you get those at sonic craft? Are those cardas?

No they are Vampire Wire BPHEX/CB.

The price is for all 4 binders for 2 speakers.

Both are excellent posts.

Do not use silicone, it's highly acidic in the curing process. Use hot glue.

Got ya,I didnt know that.Ill order a gun and glue today.
Thanks for the heads up.

Don't order a glue gun,go to wallyworld or ratshack.

Vampires are nice but my fav's are Cardas, and they cost less.

While I'm new to all these mods, isn't $125.00 extreme? I don't mind spending the coin, but couldn't one buy an above average post and put the saved funds towards a higher level cap, resistor or any other piece?

Gordon, if you think Cardas posts are expensive, price some TOTL WBT's.

Damn.I now find out I need to make the binding posts holes bigger in the terminal cups.I will borrow a drill and bits since my dremal doesnt have bits large enough.

Hey fbm211, could you please take some photos as you do this mod, and post them on here? I'll be changing the binders on a set of SDA 2B's when I get them, and your photos of your project would certainly help me. Thanks

It's a pretty easy process, unscrewing/desoldering the old ones and ****/soldering in the new ones. However as posted above, I've had to open up the mounting hold a little on all the Polk speakers I've installed new posts on.

I'm not sure who you're buying them from....you can usually find them both within a $1.50 of one another depending on where you get them. There's zero sonic difference so buy what's cheaper. Both are excellent upgrades to the brittle plastic, stock binders.

I've also not had to modify the holes for Vampire's(BP-HEX)....as someone mentioned that previously. They are drop in replacements.

WBT is horribly overpriced.

I will take some pics of mine installed tonight..

Killer site doro.Very fair prices too.
Nice bananas.

The UPS driver didnt leave the sonic craft order at my door today.I cant replace the IC posts till I get that box with all the goodies in it.
Pics of some progress later perhaps.

fbm211

Its only waiting on the cardas pure copper posts from sonic craft:D

fbm211

Pretty easy.Now to strip and bare the wire and solder to the Pods.:eek:.ETI reccomends I put a banana plug in the one Im soldering to act as a heat sink to protect the plastic..

One wonders if I should replace the stock wire with some neoteck 14 gauge teflon copper.I think from posts to xover a 14 gauge is fine but the wires going from xover to drivers should remain the same gauge which I think is 18?????

fbm211

Look at those old posts.Are they made of steel or nickel.??:mad:

Toolfan66

These pics are in my 1.2tl upgrade thread as well, You can see I added a 1/4" thick piece of delrin to the back of the cups for extra support when I tightened them down.

fbm211

stopped in my tracks.I need more power --watts-- .Had to order a weller therma boost gun which should do the job.

The 25watt and even a 60 watt I had but forgot about cant get those posts hot enough to get a good solder joint.

Thanks for that information. Good to know the Vampire BPHEX binders are a drop in replacement.

helipilotdoug

Larry, as usual a beautiful job! Thanks for posting those photos. One thing I had not yet considered doing is upgrading the interconnect. Might as well order one more set of binders to take care of that while I'm at it.

MORE POWER!!! Thanks for posting the photos. So you are replacing the wires from the binding posts to the crossover?

fbm211

Id like to---there is some serious oxidation. And what about the molex plugs? Can I get those anywhere?

dbaldus

How are you guys getting all of that glue off? Are you just cutting it out or do you melt it and then scrape it off or what?

dorokusai

I use a set of dental picks from Home Depot to pry it off. It's usually so old it comes off very easily and in big pieces.

DO NOT MELT IT....there's no need to do so.

dbaldus

Hmmm... this makes me want to tweak my own, but I am using the blade/blade version of the IC socket on my SDA SRS Originals, so I think it may be slightly different.

If I were to get the IC socket off (again, the blade/blade version), could I just replace it with a standard binding post and then solder the wires leads inside of the cabinet to the post? I'm a bit confused because there are two wires going to the socket right now (one to each blade), so I don't know what to do with the wires.

I've always wanted to do this, but this is where I get confused and stop!

fbm211

MOLEX PLUGS......ANYONE????
Would old 3 wire plugs---molex---From old PC cables they use from the power supply to the HD for example.Would they work.?
Or can I buy them.Id hate to have to direct solder from posts to xover.
