Up for auction is a Denon DR-M30HX 3 head stereo cassette deck. The deck is fully serviced and the following repairs have been done: - Cleaned the heads and pinch rollers.- Lubricated the capstan/motor shafts.- Replaced the belts and idler tire, adjusted the speed, W&F 0.055% to 0.065%. - Adjusted the playback/record heads for correct azimuth.- Replaced the audio path capacitors using Nichicon muse non polar caps.- Increased the +/-9V power supply filter caps on the main board from 100uF to 1000uF.- Increased the playback amplifier power supply filter caps from 47uF to 220uF- Increased the Dolby B/C power supply filter caps from 10uf to 220uF.- Upgraded the playback amp op-amp using the LME49720 op-amp installed in gold plated socket.- Upgraded the record amp op-amp using the JRC4558DD op-amp installed in gold plated socket. - Adjusted the electronics for correct levels using TDK SA tape. All the functions are operating as they should be, playback, record, ff, rew, pause, counter, counter memory, bias fine, headphones, dolby B/C, MPX. The performance is excellent, the sound is warm, the bass is deep, the mid/highs crystal clear with wide stereo image in both modes (play/record). The deck is in very good condition, considering the age (see the pictures). This is a 120V model, S/N 8027307338. With the deck are included the old parts and the original remote control. All the questions are very welcome. I moved recently in US from Greece, where I was working in Greek Nakamichi service during 90s and I have all the professional equipment (original test tapes, oscilloscope, wow & flutter meter, distortion meter, frequency response meter, CR-7 test unit, 1000ZXL test unit).
