Replacing binding posts on a Yamaha M-65

ipsullivan

I am looking to replace the old binding posts on my M-65 with some new 5-ways. Could someone point me in the right direction for a good replacement?

Any tips or things I should consider before doing this?

Thanks,
Ian

The problem is, on that amp the plastic binding posts are attached directly to the output board are secured to the back panel via plastic housing that was incorporated into the binding posts itself. So to replace them you must remove the output board completely with the binding posts. Then you have to fabricate a panel preferably out of metal, to accommodate the 6 new pairs of binding post. and attach it just inside the pack panel. Now to wire in the new posts you will have splice into the output leads that originally were soldered to the output board that you can no longer use, unless you fabricate a bracket for it because it too was held in place by the binding posts. But if you pay attention and take notes or mark which leads are what before removal of the output board you can do away with it all together. Good luck

Or has I suggested before check out www.legendaryamps.com as they specialize in repairing/restoring that line of yamaha amplifiers. There is some pics on that website of the amps with new binding posts that might help shed some light.

I have an M80 that works great except 2 of the binding posts are broken off at the panel. I Checked with Legendary amps about repairing/replacing, and his minimum is app $400 + Parts and he will restore the whole amp. It really is a great amp, but how much can I sink into it? How much can a fully restored M-80 be worth? It is an absolute beast of an amp and beautiful too.

I don't get the logic, Let's build a beautiful sounding/looking amp that weights 40 to 60 lbs and put 6 huge pair of cheap plastic posts on the back that stick out really far our customers will easily bump on everything. And then use rigid metal instead of wire to attach them the to board so when there bumped it will damage the board as well. Its just dumb.

But why do they use crappy Rat shack connectors?

Yeah, I like them too... Reminds me of a certain 1982 black Trans AM.

Obviously you didn't read the rules here.
You must have 100 posts before you can sell.
You still got time to edit your post.

Also this thread is almost 10 years old. The OP probably has solved the problem by now....
