Thanks John,
the project is a phono preamp with separate psu (just to make my life more complicated). So, the answer is to use correct drill size and the plastic washers suplied with the RCAs will to the job. Thanks again.Boban
Follow Ups:
I assume you'll also have a binding post for the ground wire. Isolate that if it isn't for the same reason...Ground control (not to major tom). And put the post in close proximity to the rca's..When you have the circuit up and running, wrap the phono ground wire around both phono cables all the way to the binding post..that can drastically reduce hum pickup caused by loop intercept of stray magnetic fields. That way, you don't troubleshoot hum problems that are not caused by your pre-amp.
Good luck..

"Isolated binding post for the ground wire." - that's a good point. But where to connect? There are three options here: chassis, power supply ground or signal ground. I believe that correct place would be power supply ground or chassis (chassis is connected to the power supply chassis which is connecetd to the main ground). What do you think?"Wrap the phono ground wire around both phono cables" - this I will try tonight. Thanks
My first reaction would be to star them all at one chassis point.Is your pre a diy, or a kit, or a home brew? If it's someone elses design, they may have recommendations..
Good luck, John
