I am very honest about any issues that exist, just check my feedback. One buyer reviewed me as “Honest, Honest, Honest Seller”. I treat buyers like I would expect to be treated. I am a hobbyist that buys items that need help, clean/fix them up, enjoy them for a while and sometimes sell them. I do not work on other people's equipment. If you need someone to service your equipment, I recommend Just Audio in White Marsh, MD.
