I prefer long unedited videos like this one. I think this is better especially if you want to learn! Keep up the good work!

@denispoirier19 4 месяца назад

There is another issue with this motor. I have tried cleaning it several times only for the problem to reoccur a few weeks/months later. If you look up the "solder fix" on tapeheads, this is the definitive fix for this issue. The terminals on the back of the motor and the copper tabs holding the brushes are held together by screws inside the end cap. The connection between these two pieces is not good even if the screws appear tight. Adding a bit of solder to connect these two pieces together is the definitive fix. After doing this on my unit it seems to have finally resolved the issue once and for all. Something to consider for the next time you take apart a motor like this.

I like that longer unedited format better than the usual. Mistakes are educational and fun at the same time and make your videos more fun to watch. And you have less work in post production after all. All best wishes for the recovery of your family.

@sirtainlee8725 Год назад

Love this real life, warts and all, style. Hopefully this minimizes the editing time, freeing you up for more material. The reasons I prefer this style is first, the thought process is valuable for trouble shooting, in general, and since there is knowledge not just in what 'is', but in what 'isn't', there is continuous value in this method. Thanks!

@paulb4uk Год назад

Superb work, the motor service is one of the best ways to make sure these decks run perfectly without problems .

@Hugo_Overthere Год назад

I don't think that the armature crud buildup was the problem. The problem was that the armature had worn such large concaves into the brushes that they were spanning the contact gap for such a large angle that it was robbing too much power during phase transition. You cured that.

@umeshupadhyay... Год назад

Very nicely explained this probkem, great visualization of this particular motor issue,Thanks

@bobbyk6585 Год назад

The unedited version of events presents a more realistic perspective for troubleshooting and repairing consumer electronics. It's how my endeavors typically go anyway. The polished version makes your efforts seem like they come off without any problems at all. Both formats are educational, but the raw version must be easier to produce. Great detail camera work by the way. Good to see that someone other than me is willing to do this sort of maintenance.

@smbanandanand4566 Месяц назад

Excellent video, thanks for the unedited version.

Nor Cal your the best! helped me with my Samsung DLP tv and now a customers BX-300 Nakamichi...Joe...Warren MI (semi retired tech).

@umeshupadhyay... Год назад

❤ very nicely carried out the repairs of the loading motor .First time I saw the BX 300 repais like this.Really great.

@quaner60 Год назад

You're the man, Steve! It is sounding great! Thanks for taking the time during this hard time for you. Even the whine from the motor is reduced drastically.

@johnodonoghue651 Год назад

This is a good format. If it makes your editing job easier, I'm all for it. Thank you.

@zx8401ztv Год назад

A spot on repair :-D Just as good as a new one now. I used to repair all sorts of equipment, but mechanical repairs i always enjoyed :-D

@MrVossi1 Год назад

Thanks for the nice video - helps me much! But I did the same without removing the complete drive mechanism. I removed the alu-plate, the front screw and the back holder screw through a hole in the back PCB. I also didnt desoldered the switches. So the repair is much easier and faster ;)

@rsuryase Год назад

If unedited allows you to post more frequents videos, then I'm all for it.

@davidbutler8096 Год назад

Most fans would recommend re-capping it anyway. Those things were cheap to begin with and now they're 40 years old.

@randyr.parker2698 Год назад

Oh, and yea, I like the 'longer' format, but, do it only if you have the extra time, life's busy.

@Trucam2020 Год назад

Wow. Excellent mechanically repair

@JacobFrey Год назад

Awesome video of an awesome repair. Thanks so much for doing this work and for sharing it with us. Can you guess as to why audio repair business won't tear down these cassette motors to do the repair? I know of TWO businesses that say if they can't buy a new motor, they can't repair the deck.

@norcal715 Год назад

Too bad. They are easy to repair if you are careful.

@joethomasson6326 Год назад

Awesome fix thank you sir!!

@zs1dfr Год назад

Well done on that motor repair. It might have been educational to show the voltage and current minmax's after you fixed it, to compare with the original measurements.. Hope your family is progressing steadily!

@325iaddict 9 месяцев назад

there will be not many differences. The motor sometimes just stops without a reason prior to the repair. Current consumption falls down to zero in that case.

@davidbutler8096 Год назад

Do you have a repair shop? Where? Since you have so much experience with BX-300's...I was thinking I'd send you mine. Interesting resurfacing of the commutator...Wouldn't some sandpaper accomplish the same thing?

@slt7139 Год назад

Yes please make the videos longer

@rocbolt Год назад

This worked! My BX-300 stopped playing tapes, its the geared version so all the "just replace the tire" posts weren't getting me anywhere. It seemed like the loading motor was where it was stalling out, so I did what you did, viola! Back in business :)

@KorAllRBare Год назад

Longer versions showing the fiddly disassembly and assembly.. APU I dropped a 👉👍👈

@kahlid-ataya Год назад

i love unedited videos

@giorgostexnikos6976 Год назад

excellent

@325iaddict 9 месяцев назад

EXACTLY this is what I'm doing right now, with an Onkyo Integra deck, with more or less the same transport and at least: the same motor. It indeed ate tapes, it got stuck in a position where the pressure roller was in contact with the capstan, and as soon as you power it up, you see the LEFT (supply)-reel running.... while the take-up reel did not run. After a few seconds, the auto-stop system angages and a rapid blinking of the green LED in the PLAY-button starts. Upon cycling the power, this proces repeats. While in this condition, the cassette door is stuck (of course, as the heads and roller are up). After some banging on the deck, it comes to a reset. Then, everything works... for a few times, then some other fault may be present (like no reaction at ALL when pressing a button... after a few seconds, that rapid blinking behind the PLAY button starts again). I for SURE noticed a dead spot in the servo motor: just apply 2 Volts, and brake it with your fingers until 1 rev/sec. Then, suddenly it stopped, current consumption: ZERO. Now, I dismantled it fully....

@norcal715 9 месяцев назад

Curious to know if you get it resolved.

@325iaddict 9 месяцев назад

@@norcal715 Yes, it now works flawlessly. Tried innumerable times play - ff - stop - play - rew - stop -play - stop - play - stop etc. and it never missed a command. I repaired the reelmotor of my Kenwood KX-9010 before successfully, years ago now, tested yesterday and it played a C-60 cassette fully, without stopping somewhere in the middle, so the motor still works well. However, this may be beginners' luck! Tom van der Hoff, who's spent his life repairing and engineering cassette decks, says: "this is just a temporary fix. The fault WILL come back! The only cure that works longer is to replace the motor!" Well... he still has a bunch of these motors around in his stock, which he guards with his life, but to us normal guys, such a motor is no longer available, so we have to do it this way...

@barryg41 Год назад

Good work Steve! I like the long format. Not a fan of short ones, I'm talking about the less than 1 minute shorts.

@sirtainlee8725 Год назад

23:28 one arm looks more angled at its attachment screw than the other. Also, I stopped the video here because it is one of the few positions that have the brush ends equally distant from the center. But in most other shots it seems one is crossing into the center more. May need to double check that each brush is making contact with equal force?

@underworld3721 Год назад

Good job. *****

@davidbutler8096 Год назад

Generally...I'd wager on the take-up or the loading motor. Or...bad interface between the take-up wheel and the terrible design of the rubber wheel. A lot of people put the gear drive in there, but it's quite a bit more noisy. Plus...the little motors develop drop outs and lose their way. Easily remedied by cleaning and re-lubing them.

I may be bios here but the 87v may just be the best meter ever made !

My BX-300 = loved throwing it into a dumpster, over engineered garbage. Thousands of dollars spent on old tired technology from Nak. Any two head deck can sound better than any Nak if it is properly set up for bias and Dolby level !

NICE!!!!! 🙂

@uricohen5463 Год назад

hello dear sir , i looooove your videos i would like to open a repair shop myself , can you explain what the charging method you use , do you charge for check or only when you repair ? although we live in different country . i dont know how to charge when i start my shop . can you show how arrange your lab ? , and what camera do you use to record your repairs thank you very much for you time and help

@norcal715 Год назад

I have a basic labor charge of $50/hr and a $25 diagnostic charge if not repaired. My camera is a Canon Vixia HF-R80

hello sir , i bought the blue esr meter(because of you :() , and i also have te capacitor wizard wich is analog , when i tested a 0.47 micorfarad cap out our circuit the blue esr show 9.2 ohm and the capacitor wizard show 7 ohm , also there a big difference when checking on board caps , how can i know wich one is accurate ? thank you very much

@MrMotownjoe Год назад

should reel motor be cleaned also? I have one that stops
