This is a vintage Concerton vacuum tube drawer electric phonograph. We are auctioning this item in the hope of giving it a new lease on life by restoring it to its original condition (electrical surgery). We hope that you will understand and accept this item for sale. The exterior case, which makes the most of the wood grain by painting with oil stain and varnish of the same color, has a sense of use and workmanship due to the passage of time, but there are also 3 dial substitute knobs appropriate to its age, and to facilitate after-sales maintenance, the chassis part can be removed by removing the mounting bolts of each related part, making it possible to remove the chassis. The chassis can be removed by unscrewing the bolts to facilitate after-sales maintenance. 1] For the speaker section, original horseshoe speakers have been installed and speaker cloth has been newly set up. 2] In the explanation of the tube amplifier section, four vintage ST tubes (UZ-58 / UZ-57 / 3Y-P1 / KX-12F) are used, and the dials are operated by, from the left, a mA meter (newly installed), a diode rectifier that detects speaker sound, and a 30KΩ resistor on the secondary side of the output transformer to prevent overrun of the pointer. It has been confirmed that there is no adverse effect on the sound quality and volume of the speaker. Volume volume". The main restoration work this time is "replacement of the power cord and speaker cord for safety reasons, installation of a 0.5A fuse since the power fuse was missing, repair of a missing bolt nut of the fuse halter, and relay of the electrolytic capacitor since it was in NG condition. Replaced new electrolytic capacitors "22μF 250V x 3, 33μF 50V x 1" / The contact between UZ-58, UZ-57 and vacuum tube socket was not good enough, so I repaired them.One small capacitor was in NG condition, so it was replaced with a hand-held one / The speaker output sound was high frequency (radio sound: high frequency transmission / record sound: grating high frequency sound), so a 0,01μF capacitor was inserted in the OPT primary side to adjust the high frequency sound quality / Oil maintenance was performed on each circumference moving parts such as the varicon The OPTs were made to be fully functional by performing oil maintenance on each circumferential part such as the varicon, etc. 3] In the description of the "Victor RP-7" drawer type record player, the specifications are as follows: "Power supply frequency band: 50 & 60Hz (can be adjusted with the fine tuning lever on the unit), Rotation speed: 78rpm, SP record only machine, Record needle: Iron needle crystal type, Good operating condition, Record only volume Phono motor: oil maintained and in good condition / Fine tuning lever: in good condition / Pinch roller for power transmission: rubber was hard and deteriorated, so the pinch roller was cleaned and replaced with 2 commercially available O-rings to restore the condition / Link mechanism for starting and stopping the turntable: the return spring was detached. The link mechanism for the turntable start/stop: the return spring was disconnected, which was repaired and is in good condition / The wiring system for the power cord and PU cord was renewed and replaced to normal condition / The chassis has been cleaned. The inside of the chassis has been cleaned, and the volume and switch systems are in perfect working order with no buzzing or rattling. The size is 49cm wide / 64.5cm high / 35.5cm deep, and the total weight is about 11Kg. ( We are offering about 30 iron needles as a free service. We also provide a "cleaning brush" as a free service, so we recommend that you clean the details regularly with a nozzle vacuum cleaner.)
