Thanks - in the other thread so I must have overlooked it.
Not sure what you mean by "phone jack version" - I tend to think of phone
jacks as an RJ11 (or variant) type plug.

Audio jack as the kind you find on the end of headphones.

RCA as the red and white jack plug connectors you find on most HiFi amps.
