Used for about six months. Modifications: * Applied Palshut to the noise-generating section. * TDK ferrite core on the internal power cable. * Replaced the bridge cable from the original tin-plated wire to Oyaide pure silver single-core twisted wire. * Replaced the fuse with an Aucharm red fuse (the original fuse is also included). As a bonus, I'm including an OXCO clock generator, a BNC cable, and a power USB cable (9v) ※Please use with a USB PD charging connector of 9v or higher. The clock has a temporary acrylic plate attached, but the bottom is cracked. Also, it's very fragile, so please handle it by holding the pillars. It takes a few days to stabilize, but the accuracy is higher than the built-in clock. Thank you.
