Interesting to find out through a little experimenting: Leaving a meter (my meter at least) hooked up to one side for a minute or two, the resistance will balance out really closely if not exactly the same for both sides, left or right channel.

I don’t think it’s necessary to post both sides, just avg the two or let the meter balance out a bit. Just a thought.
 
DR, these are all "inductance" readings of my carts. I posted left/right readings to show balance of channels. I connect LCR until readings become stable.
Personally, I typically don't take resistance readings of my carts, and honestly I don't understand how leaving a cart connected to a meter for "a minute or two" would/should change readings, or cause a cart to balance out left to right, a reading is a reading.

I didn't know they would stable out over that a little bit of time either. Resistance is a DC reading, inductance or capacitance works with AC signal and hence most simple meters won't do it. But just following Walt's lead that you can basically group the carts into one of the 2 1/2, or 3 basic types. Basically figuring out how many coil wraps are on each cart to obtain an impedance.

It might not work with inductance. I don't know. It's been a long, long time since I had an E.E. class. I just noticed that the Left/Right were always a bit off if I did a quick read. Didn't think they could be off by 30-40 ohms everytime so I tried making sure they were getting a solid contact on the meter leads. Tiny little posts are hard to get contact. Sure enough, holding down the leads by hand for a good 15 seconds or so let the meter (my meter is just a cheapy) get a good read and balance out. "minute or two" was just a figure of speech...should of said 15-20 seconds.

To me, this indicates that the left and right coils are probably more balanced out than we think. I'm thinking Empire probably had a way of counting out how many coil wraps for each channel. They are probably balanced out better than we think is all I'm saying. Every meter is going to be off by a little bit for error too. Just pointing out what I found out.... didn't mean to say anything more. My apologies.

If a channel is off by a couple hundred ohms, or in your case 100 mH from the other, it could be an issue. Being off a few ohms or mH's won't make a difference, hence my suggestion to just use one avg. reading for the cart. It's not going to matter if any one reading is 281 mH vs 288 mH. It's basically a 280 mH cart if you get my drift.
 
I will repost this here from the big Empire thread:

I like the inclusion of font size as another possible indicator.
 
My 2000E III Inductance;
L673/R667

Don't know why I never took a reading on it, before now.

Just found this thread. My readings:

Empire 2000ME/XIII L337 - R340
Empire 2300E L644 - R644
Empire 800UFR L680 - R681
Empire OP4 L691 - R714
Empire LTD200 L671 - R680

This is why I like this thread. I’m able to figure out what stylus goes with what on the basis of the inductance/resistance. That 2000MEX
is grouping together with the lower 66 inductance family and the 2300E is up there like a 2000E.

And then we find out about someone who has a couple of EXL 20s that group in both! Love Empire.

Sometimes life is like a box of Empire carts ... not sure what you’re going to get.

Best to always get an impedance reading on any new cart. Think I’m going to start writing it on my Empire carts as I get them w indelible ink.

What font should I use?
 
New acquisition; 200 E/X....66 clone. Inductance.....R-338 L-343

And I thought I was bad with the 66 clone collection. Now I’m not feeling so bad about my OCD Empire collection!

Seriously though I’m glad we keep going with this information because I wouldn’t have known what a 200 E/X

Nice work. If you could, maybe place this information in the big inductance thread?
