Thank you very much for your pacience in producing this video. It was very handy since I decide do repair my own TC630, which my father gave me when I was 16, back in 1969. My tape recorder was out of service for 30 years. Following your instruction I was able to put it back in action. Thank you once again.

Thank you so much. I have a Sony TC355 purchased in 1968. It sat idle for 20 years. I followed your video and now it's good as new. We're going to enjoy all those recorded albums all over again.

On the strength of this video, and a few of your other Sony R2R videos, I repaired and tuned up my Dad's old TC-350. Excellent unit. Needed a new motor run cap, a new cap in the audio chain of the playback amp board (that one surprised me), and some 3-in-one oil in a few spots - that's it. With those fixes in place, I then captured several family Christmas day recordings from five and six decades ago. Priceless stuff now. Great audio quality. Some tapes required hum removal and slight speed correction - the recorded hum turned out to be a handy reference LOL. Gotta be the first time in my engineering life that the hum was actually USEFUL! Most of these tapes were recorded on a much older deck than the Sony.

I bought my 630 at the PX in Vietnam and I always enjoyed using it. I thought (and still do) that it was one of the best looking machines of that era, and loved the big VU meters. The echo was a big plus, and would have been even cooler if it could be used on playback as well. Being fully mechanical, they are pretty much bullet proof. Although the amp was pretty decent with a good set of speakers, I mostly used it as a deck without the amp. It's been gone for over 20 years now, but I got re-bitten by the R2R bug when I pulled all my old tapes out of a box and realized I had some pretty good stuff on them, and being stored properly, they are still in good shape. I have always wanted a 630D and recently came across a decent one for a good price. Got new drive belts on order, along with some studio grade tape head cleaner and rubber re vitalizer and I'll be using this great video as a reference to get it running at it's full potential.

I wish you were not so far away I could talk to you forever about electronics,such a great channel,Steve.

Your videos are great. I have a TC-630 that just started having a problem, so I used this to help with maintenance - super helpful!

I'm not so amazed that David can take these things apart nor that he can fix things. What really amazes me is how he gets everything back together again 😀!

i've had this machine nearly 40 years. a couple new belts and some lube and head cleaning, still going strong. came with 2 detachable speakers. and it weighed a ton. also needs a new counter belt, the old one is drying out.

I've had several of these great machines ( when they work properly), over the last 20 - 30 years, I have repaired and serviced many ( the same ways you do yours), with great success. Some I've sold, and one I pieced together using better shaped parts from several machines, for my own enjoyment. These Sony's are solid well built, very heavy reel to reel tape recorders from back in the day and still, very fun to play with. Excellent videos you produce. If I may suggest...... You clean your work bench ( How many times has a vital little screw or e-clip has hidden itself under some crap you have on your work bench), and maybe use a little multiple pocket part holder to reduce any confusion as to what screws, washers, springs go where. We all have certain ways we do things, and I notice you do things a little differently than I do. Something about myself, is to have the desire to share ways I think are a bit better. I enjoy your video a great deal.Keep up the great work you do.

When I replaced a belt on one of my T recorders, I found capstan shaft bottom end sitting on a ball bearing, not sure now whether it was captive now or not. Enjoying your R-R videos thanks. Fory years ago I bought an EMI machine with 15 IPS and 7 IPS speeds on it, a very big heavy machine, which I no longer own.

Thank you! VERY informative and easy to understand video. I just bought a TC630 today and am looking forward to seeing if I can get it working. My deck has been used, but was in the original box and packaging.

Thanks for this! I am the original owner of a TC-630 that I got when I was 17 years old in 1972. So I may dig in and see what I can do to bring it back to life!

Love old VU meters always bring back a lot of great memories old stereos and tape decks

Love this picking one of those decks up Friday great video given me the knowledge to sort any issues it may have

My buddy's brother had one of these , he too was a part time musician, he would record a track at a time for each instrument, and he used the echo effect quite often..

That hard grease was just like the Mitsubishi and also the Sony VCR grease that was all over their chassis in the 80s and 90s. When ever you ordered replacement parts from Mitisu.they would send packets of their new yellow grease.I also remember Mitsubishi used a type of yellow glue on their PCBs that over time would turn brown and become very conductive.What a job it was picking that off all the circuits.

I still have Mine!! But I need a rewind belt now. I've had it since new. Has it a a lot of parties as well.

Removing the pinch arm lever: the WD-40 idea just didn't work. Lots of WD-40 and it still wouldn't budge. I put a tray under the tape head assembly and poured a small amount of boiling water on the lever where it was bound to the post. It came right off. Thanks so much for putting this video together.

Good job on this Sony I really like your videos keep up the good work

miraculously the circlip appeared after some quick handed work in placing another(with a spring) at the bottom of the stereo center logo. I seen the original circlip jump into the gap on the right hand side near the selector into the back of the machine. I owned one of these machines when I was a young man about 1968-69 UK( can't be sure though about the exact date. ). It weighed around 52 pounds with the speakers attached (again, so long ago). Elvis had one of these in one of his films too. (bit of useless info maybe). :)
