Triang Children's Record Player
Hello everyone! I recently signed up here to ask for help with this project. Anyway, without getting off topic, here I go.
I found this old record player in my grandfathers museum (He's a collector of pretty much anything and everything) and I found this broken, beaten up record player. It might be a lost cause because the damage looks pretty extensive (internally). I couldn't find anything about this on the internet anywhere, so I thought I'd ask here to see if anyone knew what repairs are needed. I have attached some pictures which shows the board of some sort and the main mechanism. Thanks in advance! |

Re: Triang Childrens Record Player
Can't see any reason why you shouldn't fix it. Maybe it was dismantled as a start to restoration and then "life" got in the way.
What are your soldering and multimeter skills like? Step-by-step, plenty of help available here. Welcome BTW! Graham

Re: Triang Children's Record Player
Picture 4 here shows where all the wires go, but I suspect it was dismantled because the amp was faulty.

Re: Triang Childrens Record Player
My soldering skills I'd consider "decent" I have an iron and solder. I don't actually have a Multimeter, but I know a place near me that I could borrow one from.
And thanks for the welcome! Alright, awesome. At least I know where the wires go now. I'm a still quite new at restoration of these kinds of things. Also, where is the amp? Know what it does, don't know where it is or looks like haha. |

Re: Triang Children's Record Player
"Amp" is short for "Amplifier".
In this case it's the Printed Circuit Board (PCB), the oblong bit in picture 2.

Re: Triang Children's Record Player
Yeah I knew what amp means, and okay. Would you recommend I buy a new one (if I can) before restoring it? Is there some way to check if it's working? Or should I fix it before replacing it (if it needs replacement)

Re: Triang Children's Record Player
Hello,
Those white plastic cased "Hunts" electrolytic capacitors are likely to be faulty after all these years. They can be replaced very cheaply with modern equivalents (which will be much smaller). |

Re: Triang Children's Record Player
Treat yourself to a multimeter. Budget ones will be adequate until you find an excuse to upgrade!

Re: Triang Children's Record Player
I would advise thoroughly reading through the thread that has been linked to in the first reply in this thread as you will see that there are possible problems with the biasing conditions with this original amplifier which may be down to bad design when originally manufactured.

Re: Triang Children's Record Player
And I would also check the condition of the stylus & cartridge since they seem to be very non-standard and made of unobtanium! That plus the amplifier makes it very unlikely to be worthwhile spending much time on it.

Re: Triang Children's Record Player
Don't forget to remove that potential solder splat/blob short on the component side before applying any power...

Re: Triang Children's Record Player
You can check the amp is working with it outside the box. Personally, I would replace the electrolytics first (cost: a few pennies or less...) and apply power so you can measure the volts about the amp. Check the mid-point of the output pair of transistors. If everything seems in order you can connect a speaker and touching the input you should hear a buzz. At this stage I'd say you'll be very lucky to get that far but we can talk you through it. A multimeter good enough for this and many other jobs should cost well under a tenner. Even QD had them a while ago.
If this is a labour of love or interest or intrigue then obvs you can't count your time in the equation as to whether it's "worth" doing. Most of us here spend far longer on a repair or restoration than could be justified by resale value but we do it out of interest and an objection to the throwaway society. Graham

The stylus is what you probably know as the "needle", and the cartridge is the bit that the "needle" is attached to. Over time, these cartridges absorb moisture and fail. As replacements are now hard to get, and extremely expensive, (£40-£50), it would indeed be wise to check that the one you have is working before progressing further. How you could test this without having another record player to try it in I don't know, but no doubt someone will come up with a way round it. Barry |

Re: Triang Children's Record Player
Not that it's going to help you with restoring this record player but just a bit of info that may interest you.
The amplifier you have is the same amplifier that Triang (Tri-Onic) used in all their "audio" products during that period. It would seem that they designed it (or had designed for them) and so they stuck with it for the following products: 1) Tri-Onic Portable Intercom (*) 2) Tri-Onic Baby Monitor (*) (*) Both products were identical except 1 of the 2 monitor's speakers was smaller. 3) Tri-Onic Portable Record Player On the instructions they recommend a PP9 (or PP7) battery. They proudly advertised: "Built In Britain by Rovex Scale Models Limited Westwood Margate"

Re: Triang Children's Record Player
The amplifier can almost certainly be repaired if it is faulty. The only component that would be difficult to get is that little driver transformer in the middle of the PCB, and that is unlikely to be defective.
The problem, of course, is finding out which component(s) are faulty, particularly if you don't have much experience. But I am sure people here can talk you through it. |

Re: Triang Children's Record Player
Given the very limited experience as indicated by the OP in these Posts and the overall dubious build quality of this children's unit, and not overlooking the issues and cost of a cartridge if neded, I am wondering about the worthwhileabilty of this task.....I guess my experience tells me that I can forsee what the OP maybe letting himself in for.
However, if it is nothing more than a learning tool in order to allow more advanced future projects, maybe I am wrong to question this?
