    Thanks for your explanation of the photo cell picking up the arm.. I always wondered why when I was skimming a record quick without going to the runout groove but to the last track, the auto return would kick in prematurely .. I didn't know it was photocell.. i assumed it was like a timing arm or something.

      There is no auto-play on the 1401, that's the 1301. With the 1401, you press start and move the arm over. It's semi-automatic i.e. no auto start, only auto return.

    Probably a polyamide lever. Not easy to break in original condition, even with gummed up mechanism, but PA relies on water content to remain tough, and loses it over time, at the same time the parts shrink slightly, and if they were fitted around a metal shaft, they will break. Can be put into a bag with some water for a few days to restore the flexibility. No matter, it's likely to last for decades as it is now that it's set into its new shape.
    Part like this likely won't scan, generally just about nothing scans properly, it's kind of a sci-fi dream. If someone were to CAD it up, a laser sintered PA part could be ordered off Shapeways, that's sensible, not too expensive. Not sure i'd want to print on my home printer other than for test fitting. If copying a part like that is needed, i just take 2k silicone from craft store, make a mould, and build up a copy out of epoxy inside the mould, made decent functional copies as durable as original of very delicate parts that way too, but i don't have the process down to where i would do it for someone else, it's not exactly efficient, would need to learn a lot more about making sensible moulds and resins. A copy wasn't needed in this case, i'm not criticising, just sharing.
    Maybe doing small-series copies of parts that are likely to break and offering these replacement parts to repairmen can be a business model of sorts? That way the design or setup costs are better distributed, while $200 for a part is of course bollocks, but at $20, it starts to look much more sensible. Clients don't like to spend more than they have to, but perhaps they'd be forced to spend a bit extra as original parts decay further, good units become rarer and more desirable, and ad hoc repairs like with welding or gluing without replacement parts may become untenable.

    The original arm lift part is no longer available, but some people offer 3D printed parts for the SL-1400. This is a common problem of this model as the part was not well designed in the frist place, it has a weak spot where it always breaks. You can find these guys on the sites of audiokarma and vinylengine.

I would love a client to bring me something and say do what you need to to restore no expense soared but that doesn't happen in the real world. I have a few people that buy and sell old stuff. They are not going to put more into something that they can sell it for.

  • @This.Here.Channel
    @This.Here.Channel 4 года назад +1

    I had to do some repairs on my sl1300, mainly the arm lifter. The lever for the arm lifter would just slide back down after I moved it to lift up the tone arm. And when the record was finished, the needle would scrape across the record as it was returning to its resting position.
    Long story short, once I got it back together the lifter stays up longer when you are automatically starting it, but if you do it manually, the lever doesn't seem to stay up as long. So I decided to try again to look online for info. I noticed that the videos on a 1200 and 1400 (and a few others) seem to show a (much) larger spring used on the arm lifter, than what mine has.
    Should all the springs for arm lifters the same regardless of the model?
    Thanks to anyone who can help me.

      I am aware of how common that part fails. I changed many back in the 80s. I also know how much work it is to get to it. I started "fusing" the part back together back in the 80s or 90s.
      What is thought to cause it, besides the lifter freezing is thermal expansion of the metal part it fits over. Seemed to happen more on setup where the turntable was sitting directly on amplifier. It all boils down to cost and how willing the owner is to spend money.

    • @SianaGearz
      @SianaGearz 5 лет назад

      @@12voltvids My alternative hypothesis is not that it's the metal that expands, but the PA lever/gear that shrinks around the metal shaft as it loses water, which happens faster if you keep it warm. PA is generally factory conditioned to absorb a few percent water by weight after moulding to give it optimal mechanical properties.

      Doesn't matter because the owner had a 50.00 limit. So the part would have to have been available for 5.00 including shipping to make it worth my while to do that. I told him he would be looking probably 100 which is low considering the work involved and he said his limit was 50 all in. So he paid me to make it a manual turntable.

Right now you can get capacitor tester that can do so in circuit. if it tests outside parameters then change it if not leave it alone.

      Yes it is and faster. To disassemble that arm and replace the part would add at least another hour in labour charges. When the client comes in and says I have a limit or 50 to repair this you do what is necessary to restore operation. Since there is no stress on the part and the only reason it broke in the first place was because the lifter pin froze, the fix will likely outlast the owner.
      RUclips armchair quarterbacks think everyone with vintage gear is an audiophool that spends 1000 on s patch cord and has unlimited resources to repair it. In reality most of the collectors are older retired people that have limited funds. They want their old gear repaired because they don't want to buy new for the limited use it will get. It was no different back in the 80s and 90s when I made a living doing this. A customer would spend 60 to 80 fixing something and it it was more than that they tossed it. At 80 an hour shop charge (that is what the shop rate was) 1 hour labour seats up most of the limit. Start adding parts and tax and people walk. It is even worse now. Some repairs I make money on, typically the high end or rare stuff but most of it I make hardly anything on, so I wont spend much time on it. There are many units that there is no video made because when I open it there is something major wrong and I know I can't do it for the limit that is placed on the repair so I close it up and hand it back. Not that the unit can not be repaired but when the cost of say a laser assembly is 40.00 plus shipping and the limit placed on the repair 40 bucks. Well you get the picture. That is why you haven't seen me replace laser assemblies on CD players. When they can go to the second hand store and pick one up for 15.00 why spend money fixing old one. I make more from the RUclips video than I ever do fixing equipment. For the stuff shipped in for repair, the post office is making a lot more than me on the repair.

      I have repaired this tonearm lift (details and pictorials on Audiokarma) about 10 years ago. A replacement part was not available back then so I had to improvise as well. I did clean the spring and shaft as well (as well as the entire tonearm assembly as I did it myself and labor cost was not an issue for me.
      The tonearm stopped working this summer when I did use the turntable a lot. It did last 10 years worth of infrequent use. I am now going to redo this trying out that part.

      23 us dollars plus shipping to Canada. A minimum of 50 it seems. Call it 100 for the part. Turntable isn't worth that. Dome people seem to put unrealistic values on turntables. Most will not spend that amount. Since you have already had the arm apathy you know how much time it takes. Very few are willing to pay to have this done when as you pointed out your repair lasted 10 years.

      The comments were disabled because there is no point rehashing it. The sender fucked up because he did not require signature, the positie also fucked up because he didn't use common sense. The other positie that was doing the route always either took it to the other door or carded it. They would card stuff that did not require a signature. I know this because I have to sign for stuff and show Id when signature was required and most carded stuff I didn't have to show Id. So everyone that was making negative comments must be postal workers now worried about their job security. When I disabled I had about 1000 up votes and 70 down votes so clearly the majority of viewers agree with me. Perhaps the system is broken and needs to be fixed. When stuff gets stolen, if it is a new item the merchant has to eat it because the credit card company will reject their payments. I talked to another postal worker and they told me they can at point of delivery card it regardless if it is signature required. So the know it alls out there don't know it all. End of discussion. He fucked up, I didn't and I shouldn't be the one people are pointing their flame throwers at. I am showing what happens and why so much stuff gets stolen, nothing else. I did nothing wrong, but said at the end, had this been stolen Canada post wouldn't be on the hook for it, I would and if the owner decided to sue me for losing it I highly doubt that you all would be paying for my lawyer bill of offering to chip in and replace it. Now do you understand where I am coming from. He was just being lazy. Didn't want to ring the bell and wait for 30 seconds to see if someone answered then go back to his truck get a card and scan it in. I don't care how overworked they are. I am overworked at my day job too. Very rarely do I get done by the end of my shift. Guess what, I suck it up and put in a few minutes of OT and get paid ot premium. Almost every day as that is what it takes to retire the work load and keep customers happy.
