No. Not really. They will pop them every time you power up the amp without a dim bulb.
That was my experience with the FRN's in this app.
I recapped my M-65 and have a few questions.

Great info thanks...are the metal film Vishays fused? The cautionary note on the print may have sent me to the world of over think.

When they burn open ...
No there not " fused" per say..
Now that you're committed to the big ass recap I wanted to share my burning questions beforehand. Notice where your idle bias trim pots are at now. Also notice where your meter board trim pots are at.
After the main board & meter board recap I've done on 3 of these amps, the right channel was happy as is but the left channel needed increase adjustment in both arenas...meter and main board. Also the class A bias check was a bit lower than the right but the consensus here has been to call it good in lieu of the differing specs between the M-60 & 65 SM's, though it's the same amp. Only difference is the meter on/off switch.
I think it's either from the Blackgate caps getting yanked or the forming within the big ass main caps. Dunno. I'm on a learning curve as well. And yes I'm prone to some over think at times.
Good thread and welcome aboard

If everyone reading this pitched in ten bucks we could get him an MX-10000 centennial edition, and a beer. Just sayin.
Ive notice 2 small but odd side effects of recapping the amp. First off, it is quieter in total volume with the same inputs. I had to move the level controls from 10 to 6 to get roughly the same output levels. This is something on the order of 3-4 db gain. I cant explain it, I would have thought that it would have gone louder..
Second off I can now hear some sort off hiss or whistle when I turn it all the way up with all the inputs hooked up and its turned all the way up with no music playing. Its faint but it wasn't there before, that I remember.
Other than that I am happy. The clarity and punch is there.

Ok the whistle issue has been solved. My tone controls, which is a JDS Labs subjective 3, was causing the issue. Flipping the bypass switch cleared the issue, and now it cant be replicated.
Is your pre-amp chassis grounded? Could cause some soundgasms. I also squirt deoxit in the RCA inputs on vintage stuff. Crap in = crap out.

My pre-amp is a JDS Atom and they all plug into the same spot. I'm not worried about it for now. If It pops up again I'll deal with it. It might just be a dirty switch.
I'm only really into the Yamaha because I grew up with both an M80 and some LaScalas and Pioneer with top tier Cerwin Vegas. When it came to building my until I die rig on the cheap, this amp was 375 working and shipped from ebay. I already knew how good these amps were and nothing came close for the price when I bought it. Im Using it to push 4 Klipsch RP-280-F's, and its amazing.
Yamaha Is really under appreciated in hifi for some reason.
I'm thinking about getting an M45 and bi-amping this.
Looks like it took 40 years for many of us to understand the build and sound quality they did in that era, minus the sonybond glue. The value of these has become so high now I've been looking at other preamp brands regretfully.
That amp driving efficient speakers like your Klipsch probably sounds really nice. Heck, I'd be using class A function all day with LaScalas.
That amp of yours was literally underrated. It's more like 185 watts into 8 ohms, clipping at 197. I just wanted to sound cool with those power specs. Most of us don't listen to more than 10 watts on any given day anyway. Plenty of room in the class A enjoyment area.
Enjoy

I'm going to follow this thread with interest as I plan on doing the same thing to my M-65.
I saw that same guy on eBay's M65 recap kit, are you happy with your purchase, or would you rather have just put it all together yourself?

By the looks of the photo, the author of this thread bought from the good re-cap seller on Fbay. Not the other hacks. I bought the same sellers re-cap kit for the PRE amp cuz I was too lazy to itemize 76 caps back in the day. The power amp has 28-30 caps so if you're patient with a metric ruler you can do it yourself for around 40 bucks with Nichicons.

I've seen threads here on capacitor lists for these amplifiers, but I believe the search bar is somehow broken for this website, as I can't seem to search for those threads
The search bar is on the work bench. Just remove the amps top cover & roll up your sleeves. And observe polarity.
Not to impressed.. A client sent one of those kits with a M-85 to me. The kit was incompleted and only four caps out of 15 or so are going to be used. I usually **** can all the old parts. Blackgates and all.
I guess I dont understand. The kit came with 29 caps and almost all of them, except for the 1000uf at c157 and 158 and 1 or two more, were Nichicon golds and green Muse's. I thought that these were the go to when recapping an amp. What dont you like about them?

It's possible there are multiple guys on eBay.

I understand, however it's possible not all capacitors are available, and I don't want to start a separate thread just for my M-65. It would also be nice to order the parts ahead of time and not have to pull the unit apart twice.
