Thank you for viewing. This is a used Technics SL-55 record player. Operation has been confirmed. The condition is also very good. This model was released around 1974. The tonearm is a manual model. To check the rotation speed, it seems you use a stroboscope on the strobe marks at the center of the turntable. You can also check with a simple app. Upon operation check, all functions are working. *Regarding the 45 mode, I don't have a 7-inch EP record, so I haven't been able to confirm by actually dropping the needle on a record. However, there seems to be no problem with the rotation speed check using a simple app. The 33 mode has been confirmed to produce sound with a record. The rotation speed has been confirmed with an app and there are no problems. Of course, sound is produced from both left and right channels. I listened to 3 or 4 LP records, and there seem to be no particular problems. Condition: Power: On. Turntable: Rotates. Start/Stop switch: Operates. 33/45 switch: Can be switched. Also serves as the turntable ON/OFF switch. 33 RPM adjustment volume: Can be adjusted. 45 RPM adjustment volume: Can be adjusted. Cartridge: Not included. 7-inch EP record adapter: Not included. Hood (cover): There are no major scratches or cracks, I think the condition is good, but there are small scratches. Notes: This is a one-of-a-kind, very old product, so returns and exchanges are not possible. Some repairs may not be possible. If you have any concerns, please feel free to ask questions. I will answer as best I can. Prices vary greatly, but I would appreciate it if you would use it with care. Thank you very much.
