Solved my noise problem while transmitting insulate your Mike jacks
In order to avoid feedback problems (squealing), the Use of this Shoulder Washer is a must if you start using ANR headsets. (No part of the Panel Jacks should make contact with the ground). And... since they were on back order, Aircraft Spruce shipped them to me a few days later without charging me shipping ! Impressive customer service !
Product was delivered as requested .
As ordered and prompt
As always processing and delivery prompt and efficient.
Only went down one notch because the photo does not match the actual washer (a lot). This caused me confusion when ordering. Not sure why I am writing this because I see you have gotten this feedback before (6 months ago) and you have not fixed it. :-)
The picture does not match the shoulder washer. Therefore its not clear that youre ordering the right part.
Yes, you will use the shoulder washer (04-00976) behind the panel with the ridge facing towards the front of the panel. The flat washer (04-00975) goes in the front of the panel. No part of the jack should touch the panel.
Both the mic and headphone jacks should have insulating washers on both sides of the panel.
The dims are 1/32" x 5/8" OD x 3/8" ID.
