Binding posts for an 8 channel amp = more expensive than the toroidals....

[SkinnyBoy]

I really want to use binding posts for my amp, but the cost is going to set me back waaaay too much...

for an 8 channel amp, you need 16 posts, decent gold ones cost $3.30 each.... thats $52.80 but then I would also need the same number for the speaker boxes.. (as I am quad amping) which brings the total to $105.60 which is just totally INSANE!!! I paid less than $100 for the toroidals I am using.... looks like I am going to have to go with spring loaded terminals, or plastic binding posts.. "high quality" plastic binding posts are $1.65 each... thats still $52.80 I paid less than that for all my filter capacitors.. its insane..

and then ofcourse I wanted to use gold RCA sockets... hmm.. 8 of those, right?? cheapest are $1.30 each... thats well, only $10 something... but I can't possibly afford it all.. I'll use gold RCA sockets... not sure what to do about the speaker connections...

making amplifiers is no fun at all.. and I still gotta make the active crossover and pre amp... thats more RCA sockets..

Good thing you're not going for something like the cardas copper binding posts. At $50/set .. well, good luck counting those pennies

now why on earth would you wanna spend that much?

I'm counting.... I have $200.... enough for the rack mount case and heatsinks... but I still need PCBs and terminal.. (speaker and rcas)

You could use a DB-25 connector for the inputs instead of all those RCA.

How many channels will a speakeron connector handle?

now thats an idea..... except I was going to use the amplifier with passive crossovers for a while... and use my existing amp as a preamp and tone controls... which means I need RCA sockets...

Of course just soldering the connections would be free, and better. As a DIYer you will always have a soldering iron to rearrange them.

... Good deal at www.goldmine-elec.com for Double-high RCA connectors (IE: a L+R in each block so look into them ), i ebelieve they are PCB mount... though you dont need to of course, your project sounds quite nice, any pics of any development yet?

good luck!

[edit: i dont know if they are gold plated, they are dirt cheap none-the-less, and would work until you get your active crossover done, btw, quality!rice in this site, its surplus, so its not like you get crap stuff, its just so much its bulk priced , but i cant vouch, never ordered from them, i will soon for a project here ) ]

as long as they were stress relieved from the components.. or it could be bad

There might be a cheaper solution. One of our local store sells these:
http://www.partsexpress.com/pe/showd..._ID=5677&DID=7

But with 4 posts instead of 2. They're priced at $3.95CAN each or $35CAN for 10. So for about $20AUD including shipping you'd end up with 16 binding posts of a decent quality. Or for $45AUD, you'd get 40 posts.

The local store has a web site but it is rather iffy:

Look for HL2333G.

Hope this might enlighten your day
