JBCODD Posted February 22, 2017 Share Posted February 22, 2017 (edited) Sirs: I have a Yamaha M-65 amp I wish to place in service after many moons of storage. However I found that the red and black plastic nuts which attach speaker wires to the outputs are missing. I've called Yamaha parts and they no longer have them. Does anyone have a source (or part #) for these? PS: I will be running some vintage Heresy I's with this, and perhaps some Forte I's if a deal goes through.

USNRET Posted February 22, 2017 Share Posted February 22, 2017 are the missing pieces such that a banana plug will still work. If it's just the 'tightening' nuts this may work. Picture??? Perhaps not.....http://forum.polkaudio.com/discussion/150518/replacing-binding-posts-on-a-yamaha-m-65 Quote Link to comment Share on other sites More sharing options...
derrickdj1 Posted February 23, 2017 Share Posted February 23, 2017 This is a common thing with the vintage Yamaha amps. The speaker terminals just dry out and crack due to age. If you open the amp and are a little hand, they can be replaced with speaker terminals from Parts Express. Make a new plate for the terminals.

JBCODD Posted February 23, 2017 Author Share Posted February 23, 2017 On the back panel there are 12 threaded, cylindrical receptacles, with an ID of 9/16". These accept cylindrical "nuts" which have an axial pass thru for the speaker wires. (Da wires go tru da middle). I could probably drill out some plastic pipe plugs, but for aesthetic reasons, would prefer OEM parts. Quote Link to comment Share on other sites More sharing options...
derrickdj1 Posted February 23, 2017 Share Posted February 23, 2017 Someone has already had the same problem. This is not how the original amp was. Open the amp up and see what you need to do. This is not a hard project once you see all the connections. Either way, the task is to redo the speaker connections and you pick what size you want. That amp is from a golden era and is why they have a great reputation in the audio world. They are worth restoring and the investment will be well worth it. Seek help from a local audio shop if needed. Quote Link to comment Share on other sites More sharing options...

The only difference is that I have lost the parts which screw into the binding posts and secure the speaker wires. While replacing the binding posts may improve the function or ease of use, I would rather take the simpler steps first and obtain the missing pieces. I do thank you for your input, though, as Parts Express may see my custom if the search for these pieces is in vain. I did contact http://legendaryamps.com/ to see if they had any on hand. Their website states that they routinely replace these posts and I hope that they can harvest a few of the nuts for me. *sigh* Da trouble I have wit "Deez Nutz" JBCODD the image below shows the binding posts with the red and black securing pieces. The securing pieces are what I need. The binding posts on my amp are functional.

JBCODD Posted February 23, 2017 Author Share Posted February 23, 2017 (edited) USNRET: How are you. I'm Ret Army. A banana plug might fit in the holes near the base of the post, (see pic above) but this would be sub-optimal as it would make minimal contact with the conductive element. Thank you for your reply, though, as the link you provided led me to a possible source at legendaryamps.com.

Matthews Posted February 23, 2017 Share Posted February 23, 2017 Don't sweat it! Keep an eye on eBay. The exact set you need will pop up for sale soon. I just checked and did not find any at the moment but they DO get listed regularly. Patience... edit: alternatively (in the mean time), find the proper size (thread) nut at your local hardware store and use as a stand-in. With a socket or nut driver you can secure the wire to post. BOOM - done Matt ♪ ♫ ♪ 1 Quote Link to comment Share on other sites More sharing options...

JBCODD Posted March 8, 2017 Author Share Posted March 8, 2017 Followed a link on an unrelated post to audiokarma.org and noticed they had a dedicated Yamaha section. Found a gent who could supply the parts I needed. Problem solved. Thanks for all the input and help. JBCODD Quote Link to comment Share on other sites More sharing options...
tigerwoodKhorns Posted March 8, 2017 Share Posted March 8, 2017 Just take it apart and retrofit something like this: http://www.newark.com/pomona/6883/double-binding-post-30a-black/dp/02J8383?mckv=wjfTwaXz&gross_price=true&CATCI=pla-162088475301&CAAGID=20389674261&CMP=KNC-GUSA-GEN-SHOPPING-02J8383&CAGPSPN=pla&gclid=CILJs5e2x9ICFZKGfgodyZkDyw&DM_PersistentCookieCreated=true&CAWELAID=120185550000925380 This should be very easy to do.
