Hello , its 2021 July , I hoped you resolve the issue of your nakamichi. I'm am a Hobbyist too, I repaired a lot of 3 head cassette that I have no idea how I did it, but it worked. compliment to RU-vidrs who upload their work. Anyway if you did not resolve yet the issue. In my opinion is the same as the last guy that commented below, if the LED counter / counter don't detect its running or turning it will trigger to stop. since you opened it already, continue dismantling it to the level you see the counter ,clean it and relube. good luck to you. my nakamichi dragon is my next project to overhaul.
Hi from France..... I don't know if you have resolved your problem but my DR-2 and DR-3 always stop like yours. I find very interesting articles : from www.teacremotes.com/nakremotes/ "Sankyo Transport Control Motor Problems The motor used in Sankyo transport decks is a major source of problems in these aging decks. The problem is seen as a deck that seems to not respond to front panel controls (play, stop, rewind, etc.) and on some decks where the transport mode lights flash after an attempted mode change. ...." next in the site... www.teacremotes.com/nakremotes/ and also a incredible video : ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-2a9YXVSpGq4.html I certainly try this.

I am qualified in making some comments here, as I have repaired thousands of top end cassette decks and Open Reel recorders over the past 40 years and continue to do so. Both the Revox and Nakamichi cassette decks are about the best anyone could buy, but the Revox B215 is in, my opinion, the King of cassette decks. I have owned virtually every Nakamichi on the market - The original Nakamichi 1000 & 700 models to the ZX9, ZX7 and the Dragon, but none are quite as good as the B215. Your tests with BASF tape is not what I would recommend, as BASF tape was never up to the quality and performance of the Japanese tapes. I used to calibrate these machines and in the azimuth adjustment (10KHz) I always saw the 'wow & flutter' displayed on my CRO. No matter how good the deck, there was always some degree of fluctuation in the side to side movement (wow & flutter) as seen on the CRO and the decks could be easily evaluated as to their stability. Many years ago, when I played the 10KHz signal on the Revox, I saw only one trace signal on PB and thought there was something wrong with the CRO. To my amazement I saw the 2nd trace superimposed (and not fluctuating) on top of 1st (L & R Channels). This showed virtually zero wow and flutter, which amazed me. Testing cassette decks at different audio levels is also not the right thing as it masks the true performance of the machines. I appreciate these are simple tests, but more science should go into making proper evaluation.
Maybe I am wrong but the slightly lower output level of the Revox is not really a lower level but some processing on the output sound. I see the same on my Akai GX 75 compared to Onkyo 2870, where the highs are a bit muffled but the sound all around has some smoothness that is very enjoyable. Onkyo is raw power, more true to the input but I find myself listening to the Akai, even to the tapes recorded on the other one.
@@jon123423 What do you want me to prove? I think I already did! I have repaired and calibrated thousands of cassette and open reels decks in my lifetime. I believe this qualifies me to make a comment!
@@sdi1111 Just repairing the product will not determine the end result! You need to do a group test by connecting it with high end gear! Amp, speaker and good source! using metal tapes from different brands!
Mods & Tweaks the results you see on a CRO emulate what you would expect to hear through your speakers and yes, I do have a very expensive system, including designing and being the foremost seller in Australia of valve amplifiers... go to:valveamps.com.au. My aural experiences are backed up by my electronic tests, using the proper test equipment. But yes, as long as you like what you hear, who cares about being so fussy!
I like the revox no belt that cool for what i heard n it sound good too the nakanishi sound good too it just two different tape deck n all tape deck don't sound the same as other two different model i like the revox cus of the sound but i like my nakamichic too n sound good too they both two of the top players got to tried whit no equalizer to hear wish one sound good whitout equalizer that it i got my nakanishi whitout equalizer n it sound good imagine whit equalizer it will sound much better
They both top of the line tape deck the revox sound good n the nakanishi sound good too but i need to hear it live to compare the different between both tape deck well i got 3 nakanishi top of the line tape deck it sound bad ass i need to hear the revox im going to buy one n check the different
I stopped watching when I saw you were playing back a Dolby encoded tape with Dolby switched off. Fail. How about learning how to use your tape recorder before trying to post any type of comparison video on the internet, Mkay?
Hi, I apologize for that. Video itself is very descriptive and I'm just describing my actions. Note about the setup: Apple Mac is connected via USB to PS Audio DLIII D.A.C. which is directly connected to Nakamichi 670ZX input so You can hear the YT sound on Nakamichi 670ZX "source". Original recording from LP Ronny's Pop Show compilation is recorded on the cassette which You can hear on Nak "tape". Nakamichi 670ZX output is connected to M-Audio external sound card which is converting Analogue to Digital and sending the signal back to Apple Mac which is recorded (grabbed) using Audacity.
I made one crucial mistake during this test and left the eq on 70ms on Nakamichi deck for the Type I tape. I will try to repeat this test with proper setup. 1.Making the same volume level for both decks 2.Setting the proper EQ on Nakamichi deck (reVox is doing the auto selection) @kastet 780 I deliberatly left the output volume as it is on both decks to show the raw impression when decks are connected to the amplifier. @MrDeckfan1 I have adjusted the bias setting on Nakamichi 670ZX when I was recording the tape. It has the bias setting under the hood, for each channel per tape Type. I had no intention of showing that Nakamichi has superior sonic quality, it's a matter of taste and personal opinion. However, if you ask me, I would always keep the Nakamichi :).
this comparison is not fair, because the Naka 670ZX adjust only the level (Bias,EQ does'nt), and Revox autocalibration setting Bias.Level,EQ . Price level is different ! The real competitor is the Naka CR7 !
B-215: Direct Drive 670ZX: Belt Drive DRAGON, CR-7, ZX-9 are better rivals for B-215 as they are newer and are more direct drive than 4**/5**/6** series.
Перед монтажом звуковой дорожки, нужно было громкости фонограмм сравнять. Громкая фонограмма всегда субъективно будет восприниматься лучше, чем тихая, независимо от технического качества. Поэтому тест неудачный. Разве, что вы хотели умышленно показать превосходство Накамичи над Ревоксом.
