Rhodium Plated RCA Jacks

HonorPC · 10:34 PM

I had 500 pairs of chassis-mount RCA jacks custom manufactured for a project that was cancelled. The markups you see on the mechanical drawing were made by me, and show the customizations.

These jacks are real beauties, sporting pure rhodium plating. I insisted upon longer threads to accommodate a thicker panel, and a body notch to accept a shield conductor directly, eliminating the usual ground lug, which can loosen and compromise the signal path. The bushing is uncolored Teflon, and the connector body has a stripe denoting channel: white for left; red for right. This is far more attractive than coloring the bushing, since Teflon dyed red usually comes out looking pink. These jacks mate in an airtight fashion; you can hear a suction "pop" when you withdraw a plug!

Each RCA jack includes an insulating shoulder washer and an insulating flat washer that, when used, call for a 0.500" mounting hole and accommodate panels up to 0.125" thick. If you mount the RCA jacks without the insulating washers, the required mounting hole diameter drops to 0.390", and panels up to 0.200" thick are accommodated.

The RCA jacks are $11.99 for a pair, comprising one jack with a white stripe, and one jack with a red stripe. Up to fifteen pairs fit into a small, flat-rate Priority Mail box. I am negotiable on Larger quantities. Below is a link to the eBay listing:

Those look very nice. Pure copper is rather soft, though. Any problems with that?

I used one for a monoblock and made the hex nut pretty tight. I would have expected the thread to strip if there were a hardness issue with copper. Brass and copper score similarly on the mohs hardness scale, as shown on the web pages linked below:

They do look nice, but it seems back-to-front to have the thread and nut visible on the outside - is there a "dress nut" to cover that stuff?

HonorPC · 18th January 2013, 04:52 AM

I just filed one with a rasp, and in fact the base metal is brass. I apologize for the mistake. I have edited my original post. Would you please remove the words "Pure Copper" from the title?

I'm sorry, but there is no dress nut to conceal the hardware.

Bolt outside the chassis is my preferred arrangement.

How much shipping to Spain?

Assuming that there are no hidden costs, such as customs red tape, the USPS site is quoting me $16.95 for a small, flat rate box that accommodates up to fifteen pairs.

Would you consider sending 6 pairs out to Australia, and how much in total?
