the way you attached the wiring to the end of the post on that banana terminal using that brass sleeve was absolutely BRILLIANT. great work coming up with that method, and i think i speak for everyone when i say THANK YOU for sharing it with us.
Thank you so much for your kind words. I have been swamped with my “real Job” so I have not had much time for more “how to” video, however there will be more
Nice work👍 I have an M80 also that needs some similar work. Not that it's binding posts got busted, but an MX1000u that got shipped to me did and I took the parts from the M80 to repair the MX1000u. Been like this for almost ten years now lol. Might get into that project some day soon. Thanks for the tips and inspiration🍻
I have a chance to get a m-40 amp. Owner says the biding post is broken. Quite confident it has the same issue as yours. Thanks for the ideas. I’m gonna try to repair using the same method
Good luck!, Im here if you get stuck. Thanks much for the kind words, much appreciated. Please join my channel and watch for my upcoming website www.red-shoe.com
@@rajoconnor Hi Randy, I used 12 ga solid copper, and fuerrels are brass tubing I bought at a local hobby shop. The original binding post ues a flat steel attachment to the circuit board inside. I opened the hole a little bit to accommodate the 12 ga wire. i bought the binding posts on Amazon, there are a whole bunch of choices at all price levels and qualities. If you need I can get a diameter on the barss if you need it.
Great repair. I see you had the "Auto Class A" turned on. Is there somewhere I can find a detailed explanation to use it or not? I have the little brother, M-60! IT STILL smokes the speakers. I've gone through at least six pairs since I bought my Yamaha gear Overseas in 1986 through the PX & AFFES!
Hi Redshoe! Amazing video. I'm curious, did you drill out the existing holes on the PCB to fit the new copper wire ends? I have an MX1000 that I'm attempting to do something similar with. Thanks!
Hi Mark! Thanks for your interest in this item. I purchased the binding posts from Amazon Prime at this link. www.amazon.com/gp/product/B07DH6Y8LW/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1
I have a M-85 that has the A speaker terminals broken and unfortunately, the circuit board is too. Would you have a recommendation about glue to repair the board? 2-part epoxy, maybe? Also, where did you find or how did you make (size of material) those brass ferrules? Thanks for this video.
Thanks for visiting the RedShoe. The first question is .Did it break the foils on the board? if notepoxy should do the trick or a very small amount of fiberglass and resin will work. For the ferrules i took the binding post and a piece of 12ga. solid wire down to my local hobby shop and looked through the bass tubing stock they had. I was hoping to find copper, but settled on the brass. it is more or less to encase the solder joint joining the wire to the binding post. I did have to grind the end of the post down abit (as seen) to make it all fit together. This was a fun project! and it saved a great amount of money on a repair Hope this helps Come back for more videos for the home audio hobbyist!
hi mike, thanks for your input. Are you referring to the back side of posts? I left them long so I could trim them for a perfect fit. What aftermarket parts did you buy? Can you send me a link? Thanks
I'm not as skilled as you that would take me along time,you should market that and make some bucks because as you said they are notorious for breaking and there are still alot out there,im bidding on a mx 800u that has the same problem I order 3 sets hopefully those will fit that m 800u also Thanks again
I want to kick myself so hard right now. I saw an amp like this last year at a flea market for 25 dollars but I didn't get it as it was broken from one pair of posts and I did not have a pre out equipped receiver

Awesome job John. Thanks for showing us an easy improvement and repair to the M-80.
Thank You, be sure to watch for more tips and fixes

@@theredshoe1315 where did you get the ferrules and what gauge copper wire did you use?
@@theredshoe1315 by the way, I got the amp and sure enough has the suspected broken post

@@theredshoe1315 done! Your idea worked to perfection .
It has the double black thumb guarantee!
yeah... i rather that not be my signature, however....

Cool repair but I would suggest using a UV mask
I got a m 85 and a and b are the same and c has shorter leads. You made that look to long so I just bought after market ones for perfect fit

👏👏👏belíssimo trabalho que aparelho bonito 💯💯💯
Nice workshop..
9:46 and nice touch with that..
13:36 well that just made the already great video, anyone can relate to satisfaction, especially from a laborious job. Nicely done.
👍
Thank you
but the cost to fix it will be more than buy a used one
Thanks nam tran for you interest. I spent $14 for parts and a couple hours labor.
@@theredshoe1315 so is total cost about 200$?
