I'm afraid not.
I feel it important to maintain standards and with respect, I have no idea of the technical abilities or the equipment, customers might have. Health and safety is also a concern and I feel a responsibility to keep people safe.
Plasma Music Limited sounds bigger than it is! The reality however, is that it's just me and I don't have the infrastructure to offer technical support to those who might want to self-build.
Despite the fact that most of my products are accompanied by a fully illustrated and detailed installation manual, I appreciate that things might not always be clear, especially if English isn't the customer's first language. I'm therefore always happy to help but giving technical support for self-builds is a totally different thing.
