Duration: 5 min recorded at the BEGINNING of the Tape from 00 min 30 sec to 5min 30 sec;The residual W&F of the tape itself is 0.022 % RMS WEIGHTED measured to NAB / JIB C5551 Standards using for playback the same MX5050 Reel to Reel tape recorder the tape has been recorded on. A few measurements of the same tape portion have been done using a Neutrik A2 analizer. The results from 0.008% to 0.036% averaged to 0.022%. A cassette reproduced using our Nakamichi Dragon showed 0.014% to 0.057% averaged to 0.035%. Cassette Tape Deck speed alignmentThe tape frequency reading gradually drops slowly towards the end of 5 min. portion of the tape. This is normal, and it depends on the deck mechanism condition. To check your deck mechanism condition do following: 1. Read the deck Speed specifications (1-7/8 +/- ….%). 2. Calculate +/-….Hz tolerance from 1000, 3000 or 3150 Hz. 3. Playback ANY tape for 2 minutes to warm up motors and mechanism. 4. Playback the 1, 3 or 3.15 kHz Speed tape from the beginning of the tape for 1 min. Note the frequency in Hz at the end of the 1 min. portion of the tape. Say this is the Frequency at the Beginning of the Speed tape. 5. Stop the deck. Flip over the cassette. The 1 min. portion becomes the last minute of the tape. 6. Playback the tape from that 1 min. position and note the frequency in Hz at the beginning of that 1 min. portion of the tape. Say this is the Frequency at the End of the Speed tape. 7. Check if the frequency difference in Hz is within the decks Speed specifications tolerance. If not, a number of things could be the reason: too high back tension of the supply reel (dirty friction felt or misalignment), not enough friction in the capstan-pinch roller pair (dirty or dried out pinch roller), dried out capstan bearings lubrication, dried out and loose capstan belt, dried out motor bearings lubrication etc. 8. Finally, calculate the Average Frequency. F average = (F beginning + F end)/2. Calculate the Average Frequency Deviation from the Tape Nominal Frequency. Deviation = F average - F nominal. Adjust speed of the deck to obtain minimum possible Deviation.3kHz or 3.15kHz 1-7/8 4.76 cm/sec Speed Cassette is suitable for tape speed alignment of any Normal-speed Cassette Tape Deck (Nakamichi DA09006A).3kHz or 3.15kHz 15/16 ips 2.38 cm/sec Speed Cassette is suitable for tape speed alignment of any Low-speed Cassette Tape Deck (e.g. Nakamichi 680ZX).3 kHz or 3.15kHz 3-3/4 ips 9.53 cm/sec Speed Cassette is suitable for tape speed alignment of any Hi-speed Cassette Tape Deck.Tandberg Cass.

Up for sale is a speed/flutter, azimuth calibration cassette for cassette recorders and players. For the speed adjustment a signal of 3khz at 0db has been recorded on the side A of cassette. You will need a multimeter with frequency counter option hooked up to line out of your deck or your phone with a frequency counter app. Just adjust the speed adjustment pot to set the frequency as close to 3000 Hz as possible. For the azimuth adjustment a signal of 10khz at -10db has been recorder on the side B of cassette. You will need a multimeter hooked up to line out and adjust the azimuth screw measuring the maximum ac voltage you can get. I used my late serial number Nakamichi Dragon to record the 3 Khz test tone as the tape speed is factory adjusted and fixed and the W&F of the deck is close to 0.015%, maybe the lowest you can get from a cassette deck. To record the 10khz test tone I calibrated the playback head of my BX-300 deck using a new sealed BASF IEC/DIN standard calibration tape (picture n.4) and my oscilloscope, and each test tape I record, I use the oscilloscope to calibrate the record head as much accurate as possible, just to prevent any cassette shell imperfections. I use only NEW TDK D-30 or Maxell C-30 cassettes. This cassette is not an original test tape, but you can get pretty accurate results adjusting your deck using it. Check my feedback for this item. 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). If you need to service your deck Ill be happy to help you. See also my other items and my feedback. Thank you for looking.

Up for sale is a speed/flutter, azimuth calibration cassette for cassette recorders and players. For the speed adjustment a signal of 3khz at 0db has been recorded on the side A of cassette. You will need a multimeter with frequency counter option hooked up to line out of your deck or your phone with a frequency counter app. Just adjust the speed adjustment pot to set the frequency as close to 3000 Hz as possible. For the azimuth adjustment a signal of 10khz at -10db has been recorder on the side B of cassette. You will need a multimeter hooked up to line out and adjust the azimuth screw measuring the maximum ac voltage you can get. I used my late serial number Nakamichi Dragon to record the 3 Khz test tone as the tape speed is factory adjusted and fixed and the W&F of the deck is close to 0.015%, maybe the lowest you can get from a cassette deck. To record the 10khz test tone I calibrated the playback head of my BX-300 deck using a new sealed BASF IEC/DIN standard calibration tape (picture n.4) and my oscilloscope, and each test tape I record, I use the oscilloscope to calibrate the record head as much accurate as possible, just to prevent any cassette shell imperfections. I use only NEW TDK D-30 or Maxell C-30 cassettes. This cassette is not an original test tape, but you can get pretty accurate results adjusting your deck using it. Check my feedback for this item. 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). If you need to service your deck Ill be happy to help you. See also my other items and my feedback. Thank you for looking.

Duration: 5 min recorded at the BEGINNING of the Tape from 00 min 30 sec to 5min 30 sec;The residual W&F of the tape itself is 0.022 % RMS WEIGHTED measured to NAB / JIB C5551 Standards using for playback the same MX5050 Reel to Reel tape recorder the tape has been recorded on. A few measurements of the same tape portion have been done using a Neutrik A2 analizer. The results from 0.008% to 0.036% averaged to 0.022%. A cassette reproduced using our Nakamichi Dragon showed 0.014% to 0.057% averaged to 0.035%. Cassette Tape Deck speed alignmentThe tape frequency reading gradually drops slowly towards the end of 5 min. portion of the tape. This is normal, and it depends on the deck mechanism condition. To check your deck mechanism condition do following: 1. Read the deck Speed specifications (1-7/8 +/- ….%). 2. Calculate +/-….Hz tolerance from 1000, 3000 or 3150 Hz. 3. Playback ANY tape for 2 minutes to warm up motors and mechanism. 4. Playback the 1, 3 or 3.15 kHz Speed tape from the beginning of the tape for 1 min. Note the frequency in Hz at the end of the 1 min. portion of the tape. Say this is the Frequency at the Beginning of the Speed tape. 5. Stop the deck. Flip over the cassette. The 1 min. portion becomes the last minute of the tape. 6. Playback the tape from that 1 min. position and note the frequency in Hz at the beginning of that 1 min. portion of the tape. Say this is the Frequency at the End of the Speed tape. 7. Check if the frequency difference in Hz is within the decks Speed specifications tolerance. If not, a number of things could be the reason: too high back tension of the supply reel (dirty friction felt or misalignment), not enough friction in the capstan-pinch roller pair (dirty or dried out pinch roller), dried out capstan bearings lubrication, dried out and loose capstan belt, dried out motor bearings lubrication etc. 8. Finally, calculate the Average Frequency. F average = (F beginning + F end)/2. Calculate the Average Frequency Deviation from the Tape Nominal Frequency. Deviation = F average - F nominal. Adjust speed of the deck to obtain minimum possible Deviation.3kHz or 3.15kHz 1-7/8 4.76 cm/sec Speed Cassette is suitable for tape speed alignment of any Normal-speed Cassette Tape Deck (Nakamichi DA09006A).3kHz or 3.15kHz 15/16 ips 2.38 cm/sec Speed Cassette is suitable for tape speed alignment of any Low-speed Cassette Tape Deck (e.g. Nakamichi 680ZX).3 kHz or 3.15kHz 3-3/4 ips 9.53 cm/sec Speed Cassette is suitable for tape speed alignment of any Hi-speed Cassette Tape Deck.Tandberg Cass.

Up for sale is a speed/flutter, azimuth calibration cassette for cassette recorders and players. For the speed adjustment a signal of 3khz at 0db has been recorded on the side A of cassette. You will need a multimeter with frequency counter option hooked up to line out of your deck or your phone with a frequency counter app. Just adjust the speed adjustment pot to set the frequency as close to 3000 Hz as possible. For the azimuth adjustment a signal of 10khz at -10db has been recorder on the side B of cassette. You will need a multimeter hooked up to line out and adjust the azimuth screw measuring the maximum ac voltage you can get. I used my late serial number Nakamichi Dragon to record the 3 Khz test tone as the tape speed is factory adjusted and fixed and the W&F of the deck is close to 0.015%, maybe the lowest you can get from a cassette deck. To record the 10khz test tone I calibrated the playback head of my BX-300 deck using a new sealed BASF IEC/DIN standard calibration tape (picture n.4) and my oscilloscope, and each test tape I record, I use the oscilloscope to calibrate the record head as much accurate as possible, just to prevent any cassette shell imperfections. I use only NEW TDK D-30 or Maxell C-30 cassettes. This cassette is not an original test tape, but you can get pretty accurate results adjusting your deck using it. Check my feedback for this item. 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).
