[@Nyck461]

I liked. Where is the video showing the re-assembly ?

[@Technics68]

Thank you this set up is the same has my tape deck i could not get the the circuit board removed and now i know why what a pain to do but thanks for letting me see how its done

[@JackSparrow-t7e]

Hello Bro I have a Technics Same but unfortunately it wouldn't Power on what to do bro

[@javiergarcia5258]

Thanks a lot Great Video Great Job

I have RS-TR373, similar like this, the gear mount on open/close windows motor broken. Where I can get the replacement? Thanks.

You can look in the service manual to see if there's a part number that you can then google for. You'd probably be better off trying to find a used device on ebay that is listed as "parts or repair". This site appears to have the service manual: www.vintageshifi.com/repertoire-pdf/pdf/telecharge.php?pdf=Technics-RSTR-373-Service-Manual.pdf Good luck!

@@silentcode12 Thanks for your suggestion. I will try.

Tinker-Ed, The screw at the bottom left of the record drive (shown at 4:14) is smaller than the other two shown holding that pcb. No screwdriver of mine fit and the bits of my ifixit set were either too big or too small. The screws on the other side of the board which you could not access until desoldering the motor are the same size so It seems to me I probably will not be able to loosen them either. May I ask what screwdriver you used? The ifixit-pro is certainly a "universal" screwdriver whose bits would seem to fit all screws. I use it to repair my computer and my phone.

[@silentcode12]

The screwdriver I used was the Craftsman 6-in-1 but it's just a Philips #1 and #2. Here's the link but it looks like its discontinued: www.sears.com/craftsman-6-in-1-screwdriver/p-00941161000P You can always use a flat-head screwdriver if needed.

[@markfalina9160]

@@silentcode12 I could not not get that screwdriverdelivered and the local store is closed. BUT I have a 150pc Craftsman set, and like you said the #1 and #2 head fit like you said! Thanks. By the way, another video suggsts using rubber bands instead of costly belts. Do you have any thoughts on that? Thank you for your help.

[@silentcode12]

You're welcome. As for rubber bands, in my experience they only work for a short period of time.They're too stretchy and don't maintain tension for very long.

[@markfalina9160]

@@silentcode12, Thank you for your advice about the rubber bands. When you solder the wire to the capstan motor, how do you keep the solder bulbs from touching one another and shorting it out? I see the leads of the PCB are lifted up, but not the motor. BTW where did you find that set of belts for $5? Thanks.

[@silentcode12]

I put a link to the belts I purchased on ebay in the part 2 video. If you search ebay for "univseral cassette belts" you'll get lots of hits. If you keep the soldering iron on the pad the solder just naturally stays where it should.

[@markfalina9160]

May I be so bold as to ask where part two is?

[@silentcode12]

You may :) There's a link in the description if you click show more.

I have the same deck which has been rarely used. Tried to run tapes on either side. They turn a few turns then stop. I have tried different tapes in case of tape binding but get the same result, they just stop. I checked both belts and they are in tact. Any ideas, anyone?

[@silentcode12]

If Fast Forward and rewind work (by work, I mean easily does the entire tape without stopping or erratic speed) it might mean the pinch rollers have dried out. I’d try using a tape head cleaner kit to see if it just a surface coating. It could still be the belts, if they’ve stretched and don’t have the tension they once had.

[@grantryder5463]

@@silentcode12 thank you so much.

[@mattbrill7909]

@@grantryder5463 If that doesn't work it could be the levers in the top of the cassette well that detect if a tape is inserted. I have a similar Technics model, the rest of the mechanism is fine but the contact in the lever needed cleaning in deck 2, as it kept thinking the tape wasn't there and would stop randomly. Quite frustrating!

[@grantryder5463]

@@mattbrill7909 thanks Matt. I gave up trying to repair it and recycled the unit instead.

[@theotherchannel2279]

Yesh you did that wrong, the whole front panel comes off in one unit leaving loads of space to remove everything. You do not have to desolder the motor either!

[@silentcode12]

Thanks for the feedback. The service manual for this model doesn't document belt replacement at all but the service manual for the RS-TR280 is very similar and does require the motor terminals to be un-soldered. The RS-TR280 service manual also details how to remove the claw to replace the winding belt. I wish I had found that first :) www.vintageshifi.com/repertoire-pdf/pdf/telecharge.php?pdf=Technics-RSTR-272-Service-Manual.pdf www.vintageshifi.com/repertoire-pdf/pdf/telecharge.php?pdf=Technics-RSTR-280-Service-Manual.pdf

[@theotherchannel2279]

@@silentcode12, no worries! It is only because I have to change my small gears in the middle, as they break up as they get old, that I knew about this! In fact, nearly all the Technics systems from the 90's come apart the same way, the front panel can be completely removed, makes it easier to work on the system.

[@theotherchannel2279]

@@silentcode12 You might be right about the motor on your one, but I think you might have been able to remove the screws and that PCB might pull out with the motor, I could be wrong, as my deck is an RS-TR333 which has a much easier cassette mechanism to deal with. Changing the belts old takes 5 minutes per deck! ;) Top tip though, if you need to change gears on any Technics cassette player, do not buy the 3D printed ones, not worth the money. Get some of these, they will outlast the unit. www.ebay.co.uk/itm/Technics-Panasonic-RDG5772ZA-RDG5772ZC-Drive-Replacement-Gear/402195542067?ssPageName=STRK%3AMEBIDX%3AIT&var=672122984575&_trksid=p2060353.m2749.l2649

Great help! Thanks. Soldering is difficult for me. It's something I must master, nonrtheless. Of course, this reminds of my old Technics CD-multi-player. (60-discs, I think.) All that required was a small o-ring, from Ace, etc.. Fixed! I'm pretty certain this tape deck is my model. Of course, nothing is immortal: It"s very rich to criticize Technics here, at this late date.
