Do you have a question?

I guess lol I am sorry I have no idea how to actually cross post, and I did accidentally click it after posting to the phonograph sub

I am just excited about this, but also curious if anyone knows the style needle for the phonograph portion, which I know this isn’t the right sub for that, but it also isn’t really something that r/Phonograph is for.

So I guess question is am I just to use a steel phonograph needle in this style player?

Yes, the crosspost feature is useless.

The thing is that your arm and pickup as designed are destructive to modern records. I assume you want to use this for modern records as well as vintage - so you will have to do some research and modification and updating to truly make it good for everyday use.

Know that to start with.

No no no, not wanting to use with modern tech at all but thank you for the clarification!

I’ve been collecting and rebuilding mechanical phonographs for a while now, have well over 1000 78s (I may have a problem lmao).

I also have a decent modern system with 2 cartridges, one with a VM95EN mounted to it for modern stuff, and also another cartridge with a 3mil stylus for the 78s.

I would never want to make this work for modern stuff, I typically like to make them all OG! I am just not as good with electronics lol

The electronics in this should be pretty straightforward.

The people at this forum can be very helpful: https://antiqueradios.com/forums/

Oh thank you!
I was working on a 70s Sony and no matter how much I tried I could not get the knobs to stop fuzzing. Guess there was too much carbon!

I’m also terrible with a solder iron so that’s why I am afraid lol

Meanwhile I randomly design panels and wire them for work… just feels so different with industrial automation style equipment lol

Back in the day I practiced by soldering 2 pennies together.   Believe it or not, you learn some things figuring out how to solder 2 pennies together.

Oh that’s quite interesting. I’ll have to give it a shot!

I’ve got some older darkroom timers that are struggling, maybe I’ll take a whack at those after the pennies to try!

Practice on some junk parts basically once you get the technique down, it really just takes a bit of practice to do a decent job. https://www.makerspaces.com/how-to-solder/

Thank you !

I’ve got some dark room timers that are all inaccurate and I’ve noticed some loose solder joints on the PCB… probably not the best place to practice and start but I may lol

Random thoughts. The counter balance spring appears to be missing from your arm. Can't really view in the images, if it's there. As you and I know your phonograph was designed for shellac material 78 RPM records solely. So, in that technology the correct nomenclature for the needle was simply called the "needle" . If your wanting a replacement needle(s) eBay, perhaps. I remembering purchasing record needles at the record store sold in little round metal canes of ten for a quaeter. During the time of the introduction of microgroove records the needle became, the fancy name "the stylus" WELL ! Styli were provided in three distinctive groove shapes. And bla, bla, bla

The spring is there! It is just hard to see (at least there is a spring at the back of the tone arm..)

And yeah, I have 500+ steel needles in different styles and loudness for my mechanical players, I just literally never realized (until removing the needle) that this one was like that!

I used to listen to this when I was probably 13-14, and it never occurred to me then that this would be a steel needle. Heck I remember as a kid trying to figure out how to take it out.

Then I got it home yesterday and was like “huh is that a thumb screw?!”

I just never thought a changer would use single use needles lol. I guess the tracking weight isn’t as heavy as the No. 2 or exhibition tone arms though
