Collux Thank you for your efforts.
I'm still unsure, where your pictures show the Green wire, mine is marked R, and the Blue is marked L .
Anyone else perhaps?...Cheere

Hi Spacepacker
-happy to be of some help

https://www.usaudiomart.com/details/649 ... s/1423580/
This further image is indicating (when the needle is pointing uppermost) and reading L to R on the pins:

Needle @ top

Blue Green

White Red

Which aligns with your Green 'R' and Blue 'L'
AND this is also in agreement with the Audiogon post I listed.
(Although there is not enough information given there for absolute certainty.)

So provided the cart in the image has been correctly wired in accordance with the manufacturer, this configuration should be good.

Still getting the "hang" of posting, my 3rd effort,
Collux It didn't work, missing left channel.

Looking at the clear the picture of the cartridge in the playing position the difference is,
his green wire is R on mine and His blue wire is L on mine, other pins are +.

So I am still stuck, I should never have taken it off,

Trouble I have is my "Oricle" is a fixed head...Cheers

I don't think this situation is terminal just yet. (fingers crossed!!)

The 2 channels, BL/Wh and Rd/Gn of the cartridge, now need to be tested.

Details on electrically checking the cartridge:
https://www.vinylengine.com/turntable_f ... 19&t=22754

Should this test out OK. Then your cart is good but it indicates, that you are likely to have a bad connection (or some other problem), further down the audio chain.

Possible: headshell/tonearm/preamp-amplifier poor connections.

Once identified, this will need to be corrected.

Collux.
Sorry for the delay, had to spend sometime in Hospital.
Thank you for your help and efforts!
With my vision I cannot trust myseilf to use a Multi Meter on pins so close together, I would have a short!.
I have other catridges, so I will leave this one for now.
Once again Thank you and to All...Cheers

Hi Spacepacker,
If you could get someone to assist you, testing of your Supex may be possible.
Notwithstanding, your option to go back to other cartridges is a good one.
It will confirm one way or another, if you have a problem with your turntable wiring/amplifier chain etc.
Regards, Colin.

NEVER "check" wires on an LOMC with a multi-meter. LOMCs use the thinnest wires possible, to reduce mass. They handle the 0.2mV output of your Supex — but a meter puts many full volts (not milli-volts) through those wires. My best meter uses 9V, orders of magnitude greater. It could melt your coil-wires in a flash.

The worst part is you won't even know you caused the damage. You'll just think "Oh, the coils are shot. Too bad."

Good advice bimasta. Thanks for pointing that out.
(I dont use MC cartridges, so had not considered that aspect.)
The best test therefore of the OPs 'system' in this situation, would be another cartridge.
- preferably one known to be good.

The way to test coils on an MC (continuity) is to make a lead with 2 RCAs on one end, and 4 cartridge clips on the other. Connect to Preamp and to Cart, and lightly brush the stylus, with a stylus cleaning brush. If the coils are good, you'll hear sound from both channels, and they'll be equal (balanced). There's no need to go through the hassle of mounting/aligning the cartridge to do this easy test. Save that lead for testing others.

MM/MI carts may use thicker wire, and be less fragile, but I still don't take the chance. And not all meters are the same in this regard: I have one that uses a 9V battery, another only 1.5V. The big one is "better" for most things but the small one is safer.
