The exterior has paint chips, small scratches, and dullness (Mizusaki Ryo) Maintenance information: 2024.1.25 Maintained (after disassembling the switch, the upper contact component part is cleaned with organic solvent, mirror polished, and treated to prevent oxidation. The equipment used for wiring was all Teflon AWG32 (same wire diameter as the original one?) After changing to it, redo the wiring. Caulking has been corrected due to looseness on the hot side of all input/output terminals. Since the caulks on the ground plates of all pin jacks are loose, they were fixed and reworked by soldering. Attach an input/output identification tepla sheet to the pin jack. Good input/output tests) Accessories: none Main specifications: boost ratio 31 times with bypass function, primary impedance 1.5 ohm/secondary impedance 1.5 kΩ dimensions W90 x H68 x D88 mm weight 420 g
