List member Frank Hughes posted links to photos of his version back on 
4/4/15.  He used an octal base with a popsicle stick to support the 
MOSFETS.  Unfortunately, the links are dead now and I forgot to save 
copies of the photos.

Building it into an octal base (octal plug) makes everything easy, and 
completely reversible.

You will be thrilled at the improvement it makes in the audio.

Best regards,
