Review on Bluetooth Headphone Receiver ESS9023 Control by Heather Brown

DOES NOT PROVE that the tubes supplied with the FX-Audio Tube 03MKII are a MATCH PAIR. In fact, the tubes were NOT even boxed. They were FREE in the box and just floated around. The manufacturer wrote me a message that they match. If you look at the separate advert for the "MATCHING" pair they are SHOWN IN BOXES with THE MATCHING SPECIFICATIONS printed on the boxes. The Tube 03MKII didn't even have a separate sheet with the characteristics of two lamps.
