Continental 1 Hum

This may sound a little crazy, but try running a ground wire from the mechanism chassis to the amplifier chassis to see if this affects the hum.

Some ground problems are elusive.

Thanks Marty

I have tried that without success.
I removed the 'half-way' plug and my meter is detecting a very small short in the tone-arm wire leading to the cartridge.
This may be the problem.
I can't find a local seller (in Australia) so will need to order from Stamann etc.
It'll take a few weeks to arrive, hopefully this will fix the problem.

I can only buy stereo cable, I suppose this will be okay.
I'll let you know.

Cheers

Hi Marty,

Thanks for sticking with me on this.

I think I fixed it!!

I bought some shielded audio wire from the local electronics store.
It was a little thicker, but I was able to massage it into place.

I rewired the tone-arm, new connections to the cartridge and re-soldered to the amp, particularly the mid-way plug.

Hopefully it will continue without the hum, more testing required.

Thanks Gordon....

Good news! I'll keep my fingers crossed! 🤞🏻

G'day Marty and Norman,

I'm calling it fixed!

I gave it a good work-out and the hum did not return.

It was a reasonably straightforward fix, I just did not know where to start,
the knowledge that people share on these forums is fantastic...Thanks again

Gordon..
