That would be SU carbs
No, what I wrote was correct.
I am putting in SU's to replace the crappy carbs they provided to the US (as in United States, not SU backwards) which were a pair of Strombergs. In the UK they skipped carbs and went with Lucas PI system.
Bodyblue, I learned to drive in mid-60's muscle cars with bias ply tires (IIRC they had H78's though - D78 was a pretty lightweight tire). I'd no more tailgate someone in one of those than I would rely on my modern tires to let me tailgate even if they're brand new Pirelli P0's. I also live in California where idiots rear end other idiots on the freeway literally every day, pretty sure you're at more risk from sharing the road with them than you are from someone driving a classic car on bias play tires that is actually paying attention.

It's sort of a pet peeve of mine but not that big a deal. Just wondering where others fell on this. Do you like when LEDs are swapped in to replace the original-style lamps on vintage receivers or not?
Stock incandescent bulbs back in. Kinda sorry looking, but that's how Yamaha intended the lights to look so...
@jobrewer1983 It crossed my mind when I posted it that it might be informative to restorers (of course my 3AM jumbled phrasing of the question makes the results a little bit unclear, but I think most understood what I was asking). I think a good portion of people may not understand that there is a visual difference at all. Whenever I bring up the difference between the LEDs we are putting in our houses, offices, and street lights to people, I usually get a blank stare in return. To someone like me who pays a lot of attention to visual things (and is also very sensitive to light), the difference is dramatic, and not at all trivial. To me the old style lights match the era and 'vibe' of the old receivers - no right or wrong about it, but definitely a preference I have (at least currently).
It's subjective but I prefer the original look.I'll never do leds on the few vintage I have chosen to keep.Agreed^^
I was using 10-100W HO LEDs for reef aquariums back in the early 2000s. I'm pretty sure I still have a few chips and power supply's around somewhere. I've also modded out a few projectors with chipset LEDs they can be a lot of fun to tinker with, and so have a lot of good applications. I just don't feel Audio is one of them. It's a fun project, but really is not worth the time.
Dowojo is an member who has access to most original lamps. For peraonal 1250 build I used his lamps. I feel they look better than LEDs. Uts all subjective, but knowing what others like can actually be helpful!
What a great thread!
...some of the people that retrofit them willy-nilly do a shit job of it and leave the equipment in a condition where it can't be made original again in the process...
Not wanting to bog down this thread with pictures, here's a link to a new thread I just made in the Yamaha forum

See my link above and by all means, comment.
It is 'kinda sorry looking' because that is NOT how Yamaha intended it to look and it did not look like that when new. Incandescents (especially small ones) degrade in light output massively over their lifetime and the spectral output shifts more to the red end of the spectrum. Yamaha used those small greenish/blue filters on that series of gear to 'clean up' the light when they were new.
When new, the diffusers were also white- now they are yellowed and when combined with dim incandescents, it looks simply dreadful. In addition, the dial pointer perspex gets yellowed from UV exposure.
With the Yamaha meter diffusers and dial pointer bulb holes, it is a great idea to paint white enamel around the yellowed bulb mounts and install warm white LEDs with appropriate current limiting to ensure perfect illumination.
I'll try to find the shots I took when recently doing a CR-820.
