Deletion of Hughes & Kettner

Comment: I'm not sure about the book entry, but the first review is not from a |reliable sources and the second is a passing mention. If it had been a feature article on the amps or the company, that would have mad a difference in my opinion. My Google search reveals entries from a lot of music stores, fan forums and sales sites (like ebay). https://www.gearnews.com/manufacturer/hughes-kettner/ lists some of the company's recent press releases. If they had listed other sources, that too would have made a difference
