Welcome to part 2 of the Nakamichi DR-1 upgrade project. In this episode, I’ve found a solution to make the capstan motor run continuously, eliminating the annoying speed ramp-up during the first 2 seconds of playback. Additionally, I've recapped the deck with solid polymer Nichicon capacitors, resulting in a remarkable improvement in sound quality. Now, you can hear every detail. The measured W&F is an impressive 0.035% WRMS on average.
🔧 Upgrade Highlights:
Continuous Capstan Motor Operation: Discover how I resolved the speed ramp-up issue, ensuring the capstan motor runs smoothly from the start.
Solid Polymer Capacitor Recap: Follow the process of recapping the deck with high-quality Nichicon capacitors, enhancing performance and reliability.
Sound Quality Improvement: Experience the enhanced sound quality with the deck now able to record all tape types flat up to 21 kHz at -20 dB. With Dolby C, it records at 0 level up to 17 kHz, gradually dropping to -3 dB at 20 kHz, comparable to CD player quality.
🎶 Performance Metrics:
Wow & Flutter: Achieving an average W&F of 0.035% WRMS, ensuring stable and high-fidelity playback.
Recording Capabilities: The deck's ability to handle high frequencies with precision, making it a top performer in audio recording and playback.

@ilestojanov6140 on playback deck should correspond to IEC curve, to be compatible with other decks, on playback level should match to be compatible with other decks Dolby system. And the best decks produce linear curve compared to the playback. When I talk about response, sometimes I mean playback response when measuring deck to play using the test tape, and when I record I mean record response. I hope I explained.
