Thank you for looking at my shop!?Hope you have the best shopping! ! ??CONDITION LEVEL?? New-Unused-Excellent-Very Good-Good-Acceptable-Junk Condition:Good Operation: OK ?Operating normally. In a word, it is energetic and has high sound quality. ?The mid-high range has a sense of transparency, and the sound quality has a sharp rise. ?It has two speaker outputs, which can be selected with the front switch. ?While non-feedback is popular, it skillfully uses NFB and PFB, and provides a high level of overall sound quality. Appearance: Dirt and scratches I cleaned it thoroughly, but there are scratches, dirt, rust, etc. Overall, considering its age, there are few scratches, and I think it is a relatively clean instrument. Completed repair - Internal cleaning and dust removal - RCA input terminal, phone jack cleaning, polishing, rust prevention - Tube fuse terminal polishing - RCA terminal polishing and cleaning - Speaker terminal cleaning - Board solder side cleaning and correction - Parts surface cleaning with IPA - Block electrolytic capacitor clamp repainted - Replacement of deteriorated parts - Voltage switching relay and two protection relays disassembled, cleaned, contact resistance measurement - Silicone grease removal and reapplication of final stage device - All front switch buttons disassembled, cleaned, and disinfected - Level adjustment of large power meter, which is a feature - Check B voltage, DC balance, idling, clamp voltage, etc. adjustment Note The following points are different from the original. - All indicator bulbs on the front have been changed to LED - The use of LEDs of the same color as the indicators gives a high level of purity. (limited_power,protection,main,remote) - Power meter lighting bulb changed to LED. I dont think there will be any worries about it burning out for the time being. ?Avoiding white LEDs that can be perceived as bluish-white, we have gone for a warmer, more visible color that is closer to that of a light bulb. ?The angle of illumination of the LEDs has been taken into consideration, making the meter display clear and easy to read. ?The LEDs are designed to provide uniform, even lighting rather than brightness. (See photo) ?The meter will not turn off even when limited is selected. (The original meter lighting is turned off.) ????PAYMENTS???? ?We accept PayPal and all major Debit / Credit Cards. ?We can only ship your item after your payment clears. ?We ship within 10 days of payment. ????CHECKOUT???? ?Please check your address before paying because we can ONLY ship to addresses that are entered before placing the order. ?We cannot change an address after the order has already been placed. ????SHIPPING???? ?Packages:Box or envelope and Bubble wrup ?Packages usually leave our warehouse within 10 days of payment. ?We provide valid Tracking Numbers for all orders. ????INTERNATIONAL PACKAGES???? ?All our international packages ship under the Fedex or Japan Post or DHL. ????CUSTOMER SERVICE???? ?If you have any questions or issues, we are at your service. ?You can email us anytime through eBay messages. ??RETURN INFORMATION?? ?We offer a standard FREE 30 days refund or exchange policy. ?Item must be returned in original condition in order to receive a full refund. ????Customs duty???? ?Import duties, taxes, and charges are not included in the item price or shipping cost. ?These charges are the buyers responsibility. ?Please check with your countrys customs office to determine what these additional costs will be prior to bidding or buying. ?We cant not reply gifts or unreasonable requests such as declared amount.
