No fan needed with instruments such as a guitar. As far as the rest of your question – I do not have boards for sale, – I can post the art work for my surface mount version and you could have the board fabricated and make the amp yourself. I am going to create a version of this amp with a thru hole layout and some minor tweaks and post the board artwork.
you can send me an email at raycharlesring@gmail.com explaining with a little more detail what you are trying to do and I will see what I can do to help you build one.
