Wurlitzer 1700 Static sound

[gordo]

Hi All,

I am trying to help out a friend.

She has a Wurlitzer 1700 that has a lot of loud static as the tonearm moves onto the record to play.
Once the record is playing the static is gone.

However, the static is also there if I move the tonearm off the record whilst it is playing. It is very loud!

I replaced the Cobra needle without any improvement.

I assume the tone arm wire is shorting somewhere on the metal of the tonearm.

Am I correct?

How can I check and fix this?

Regards

Gordon....

Hi Gordon,
The Cobra operates through ca-axial cable and the outer sheath is grounded at the arch on both sides - so it's exactly the opposite you're probably looking for, a ground that is missing.

Thanks Norman,

I'll try to find the problem and let you know.

Cheers Gordon..
