This is the Triode phono equalizer, TRX-EQ7. Purchased from Denki-do Square via Amazon on September 30, 2024. It has a manufacturer's warranty until September 2025. Operation has been confirmed. It is generally clean, but there are minor scratches. Please refer to the photos. Includes the dedicated power cable, instruction manual, warranty, and sales receipt, but the original box is not available. It will be carefully packed with air padding and shipped in a separate box. I am a non-smoker and do not have any pets.
