Adding an audio jack plug lead to a C2N Datasette

[Beaps]

Oh my I thought it was only me trying this stuff lol. I have been banging my head for days trying to sort this out.

What I have is the inners of a cassette that I am trying to add a mono plug to. I have done this on the +2 but I cannot find the two points for jack.

Any ideas?

I had a idea of using a old BBC Model B data recorder to record the wav files from my PSP to tape.I play my game from the PSP to the wire I soldered on the board of the CN2 and it works fine.
