Hi Joy,
I cannot see your drawings as I cannot open the links through this security firewall.

But from the text you wrote it sounds logical and beneficial to block DC between stages. It is normally common-practice.

This should work right? 

The AF needs to be coupled via DC blocking capacitor to the source of 2n7000. RF bypass cap from source to ground is also needed. It should provide a clean SSB output. Your thoughts, Harry?
