FX-AUDIO TUBE-P01J Vacuum Tube Amplifier I purchased this here two months ago, but it didn't have enough power for my system, so I'm selling it. I was told by the person I bought it from that it's a tuned model with matched pair tubes, but I can't confirm this as there are no markings on the product box, etc. I haven't experienced any problems while using it. It produces a delicate and beautiful sound. The exterior is in beautiful condition with no noticeable scratches. It's a beautiful item, but it's used, so please understand that it's non-refundable and non-returnable. The included accessory is the power adapter. Thank you for looking.
