The plugs go almost by force to the RCA - sockets !!!, not the point.
Was scared me to push my sleeves into the housing or the mechanical holder (solder joints?) To push loose !!!
Connector to the gilded holding tongues of the plug easily bent with pliers!
Then carefully tried until lightly clamped to the plan went sockets !!!
By gilding should be given even in less tight fit of the contact.
Therefore, there is of me for this article only 3 stars ...
