Conn "Microtuner", I have taken one apart myself now, and more importantly put it back together more usable. SPECULATION with multiple guesses as support. The Conn "microtuner" a knob adjustable tuning slide, moves 5/8" out from full in by 20 turns. Slide movement can only be seen between the far end of the knob you rotate and the neck. If the knob turns then the "microtuner" is almost certainly in fully functional condition. You can remove the microtuner assembly by continuing to turn the knob farther out in longer pitch direction, and pulling it off. Then you can clean and oil the tuning slide surfaces and the 2 symmetrical dove tail lugs that keep the slide from turning when you turn the knob. You can unscrew the retaining ring at the front by removing the set screw in the side that passes through a hole in the retaining ring, you can clean and oil surfaces near the retaining ring if you do that. Use only screwdrivers that are an excellent fit on saxophone and smartphone screws (tool hint). If the adjustment knob rattles around enough to distract you, then put lanolin ( heavy-duty grease removed from sheep's wool ) in the tuner threads on the saxophone's neck ) Screw the knob adjustable tuning slide all the way in, rotate adjusting knob so retaining screw is on top. Then turn the tuning slide 10 tutns out. Then tune your saxophone by the common method of how far you push the mouthpiece on. If you have the Big Toe weather station inplant, then I am 93.92% sure you can adust saxophone pitch between indoor and outdoor temperatures by one microtuner turn for each Fahrenheit degree difference, pretty cool for 1922, they thought 100 years ahead. If you're over 40 get the $15+/- headband magnifier on Amazon, it's much better than the expensive ones and you'll be able to manage the flea size retaining ring set screw and work on your phone too
If any of y’all are interested, I would very much recommend checking out Matt Stohrer (of Stohrer Music) here on UA-cam, if this kinda stuff interests you. He’s a saxophone repairman that specializes in vintage saxophones. Very interesting and informative!
Measure the diameter and guess length of screw hole, Write down in both English and Metric. Check watch and clock restoration hobby supply vendors for flea size screws. If you have money to burn buy a tool set for smartphone repair.
I used phosphoric acid. Here is a link to a video I did about my chemicals. "Tour of My Instrument Cleaning Room: Intro To Chemicals" ua-cam.com/video/wBaILXIfERI/v-deo.html
You need to be careful to rotate the bend around the point where it needs to bend. If you do it the right way, there is a small chance it will break. If you bend it in an uncontrolled way, there is a lot more chance that it will break. It is very hard to explain the technique in words. I have not yet done a video on this yet, but I will try to publish one in the near future.
A weirdly overdesigned system. It's no mystery why nobody else adopted it. Besides having to mess around with the tiny screws and the spanner rings, the outboard end of the moving part is very thin and easily damaged. Particularly on C-mels (which basically have people mystified so that they try to do awful things like cram alto mouthpieces on), that end can take a beating. I wish I had some long screwdriver inserts like that.

Fascinating! That must have made it much easier to tune, at the expense of keeping it clean.
Great video.
The MacGyver of instrument repair. Very fascinating....
The vice trick was super cool! Thanks!

I have Liiman backhome just thinking to change to Tenor neck but some vdo advice they are same path
Wow. Never seen that before. So complicated.
Servicing old odd random neglected parts is a bit complicated, but it is only two moving parts.
Thanks,what chemical did you use?

Hi great vid!
On my sax the pin key that pushes the crook key ring is bent and I’m afraid that if I force it it’ll snap any tips ❓

You have to decide if you want to risk it. You may be better off taking it to a repair shop.
Ok thank you 😊
How you comment that 😆 without sound is better !

teacher, forgive me for giving you my opinion, I would remove the octaba key and I would work better thanks
You are correct. I should have removed the octave key first.
@@TheBrassandWoodwindShop l thank
@@javierquesada798 Good tip to remove the octave key!
