View Full Version : Some advice please
Hello
I am hoping i can get some advice please. I have my 2 1210's indoors but i have a 3rd that has been in a shed at bottom of garden for quite a few years and it is in quite a poor state. I have been reading up and there are quite a lot of tutorials on you tube and I think i could rebuild it.
Could you please let me know if it is worth it and would it cost too much?. If not then please could you point me in the right direction, for example where to get good spares.
I do plan on this taking a while on this so i am not in a rush and i am looking forward to building a deck myself.
Thank you for any reply
Ian
pics please,1st thing to do is get in in the warm and out of the shed.
Thanks for replying Jamie. I have moved it indoors and took it apart but yes i will definitely gets some pics and see what you think.
Value of a good one is (at the low end) about £300 these days, you might want to take that into consideration when evaluating the cost of a rebuild. Like Jamie says depends on how bad it has gone. They are very well made things so it will take a lot to kill one completely.
Its not letting me post many but you can see not too bad from what can upload. I know will need quite a bit done

You can post more and better photos if you use an image hosting site.
The Technics is certainly restorable. I'd concentrate on getting it working properly before getting involved in the cosmetics though.
Yes i guess my main thing to do first is make sure the main circuit board is still working. Any advice on how to do this?

Surface corrosion as would be expected by the look of things. A visual inspection is the first thing to do.
Release the pcb mounting screws and see if you can see/get to the underside. Look closely for any corrosion of the copper tracks, most pcbs have a resist layer on the tracks to protect them.
If there is any verdigris then use a stiff brush, an old tooth brush will do, to remove it. Look closely at the soldered joints for 'dry joints', these usually appear dull or you can see a feint crack around the component lead.
Likelihood is everything will be OK :goodluck:
Thank you Alan that's brilliant news i shall give that a go and give an update :)

If you've already got 2, you might as well chuck this one, or flog it on fleabay for £50? OR you could spend £2000 on upgrades, then buy a £2000 arm, and its the deck of your dreams, risen from the dead!
Having a few good ones to refer to can be helpful. A Schematic would be good if you have to repair the electronics. Once you've cleaned the board, spray it down with a quality circuit cleaner, outside so you don't fumigate yourself. And re-solder any suspicious joints, or all of them if they all look cloudy. Old corroded solder points can actually cause resistance, which gets hot and also changes the value of the circuits. Any suspicious looking components, you can un-solder one leg and lift it to check its value with a meter. If it does not have a value written on it, that's when a schematic comes in handy. Any swollen caps must be replaced. Once you've got the circuit looking proper, be sure your motor is in order. Make sure all bearings are free and clean, a drop of fine machine oil if need be. Should be an interesting project!
If you can get all parts off of the plinth, then you can see about cleaning that up. If it's pitted as it appears to be, rub it down with steel wool, in the direction of the grain. And you can get some anodizing die and wipe it on evenly. (If it is aluminum and not plastic) Possibly even cleaning the raised areas with an emery stick. Or better yet, send it out for powder coating? Or paint it with an air brush? Opportunities to customize here. Looks like a fun project!

And I don't know what your soldering skills are, but using a cheap iron with a large tip can cause more damage than good. These days you can buy a soldering station with temp control for affordable prices, use a fine tip on your iron. And keep your tip temp down to 850 F. Use a real thin rosin solder, 0.031" or .8mm, and do not over heat any one spot. Practice on something that doesn't matter if you have to. There is a lot of information on the web about soldering if you need it, even I learned something reading up on a few sites, and I used to solder for a living. If you resolder all joints, use circuit cleaner to remove any excess flux and it will look most professional. touch solder to each joint you resolder to wet the tip, but only add a tiny amount to the joint unless it falls down the hole and you have to fill it up, many cold joints will do this. Have a solder sucker on hand if you get too much in one spot. It's not as hard as it sounds, and developing good soldering skills is a handy thing to have. And I apologize in advance if you already know all this. You may clean the board and it look fine and no soldering will be needed. If so, I apologize again for wasting all of this digital paper.

Hi Russell.
Thank you for your advice. I have done some Soldering before but your info above is just what I needed and I have a iron on order but i didnt know things like thin rosin and that so thank you. I shall be buying all the things you mention and give it a go. I do intend to spend some time on it so im not in a rush.
I wasnt sure if the the top plate part (is that what you call the plinth?) was too far gone but i will try what you suggest..
You definitely have not wasted digital paper.
Hi mike
Yeah im giving myself a project on this one, going to take my time and make it nice but im sure i will be on here quite a bit getting advice.
Haha, dont know about a £2000 arm but nearly that, maybe :)

Glad to help! And from what I see these 'tables selling for, it is definitely a worthwhile project! And yes Solder is a deep subject. So many kinds, and sizes. If I can help in any way just ask. Here's an idea! Cover the plinth with gold leaf! And cover with clear paint! (Im only half way kidding) ;-)

At the moment maybe, but I bet it can be resurrected. Definitely worth a bash! :)

Cheers , I agree but thanks mikeyb too :)
Looking at what you both have listed, im inspired.
