These are some of the amplifiers and mixers that I had time to look into. I documented them for my own personal records. Otherwise, I’ll forget what I did. I’m sharing these information so that others may have a better understanding of what audio electronics is all about. Please do not contact me regarding how to repair your amplifiers. I do not offer repair services nor do I have the time to teach anyone. |
