For securing the power transformer, a transformer base that floats with resin in a cast trunk case, common with the higher-end model DCD-S10IIIL, is used to cut low-frequency noise (Image 14). Equipped with AL24 Processing technology, it is a popular model with a reputation for sound quality, combined with a Burr-Brown 24-bit DAC (PCM1704). In preparation for listing, the pickup lens was replaced, and silicone grease was applied to the sliding parts. The tray opening/closing rubber belt was also replaced. Since there are cases where the L-channel DAC often fails due to its own heat generation in the DCD-1650SR, heat sinks have been attached to both channel DACs (Images 15 ⇒ 16). The previous owner seems to have handled it carefully, so the condition is good. Also, low-viscosity high-grade oil was applied to the oil-impregnated bearings. Playback was confirmed to be working without any problems for both channels via RCA for analog and OPTICAL for digital. There is no crackling in the PHONES output.
