Hi everyone,
It seems that 1202s are trending right now so thought i'd throw a few questions at you and see if you can help! I've gone through the other threads but can't find the information I need! I've only recently caught the B&O bug so i'm still new to all this! I've just bought a BG 1202 which was described as being in working condition. When I got it, the belt had slipped off and I found that the original 5 pin DIN lead had been removed and converted to an RCA output lead... no good for my Beomaster 901 so i'd like to try and convert it back to how it should be!! I made sure all the transit screws were in place and the platter was removed during delivery.
Firstly, I need to re-attach the belt so... How do you remove the under platter so I can get to this?
Secondly, the small flywheel that the belt attaches to seems to be loose, as well as the adjustment knob underneath the deck. What exactly do I need to do with this and how do I tighten it up so the belt does not come off again?
Lastly, In order to convert the output back to a DIN lead, I presume I will need to remove the main case. Do I do this by undoing the screws on the base and lifting off the top? Also, How do you remove the pick up arm as I guess this will need to come off in order to lift off the top.
Sorry for all the questions and thanks in advance. I've attached some pics to illustrate the what i'm talking about!
The cable for the DIN 5 pin is a shielded cable where the inner wires each are shielded, and these all have an outer shield, there is a manual onsite for silver and gold members, where you can see how to connect them.
There is no need to remove the under platter to place the belt, and check this thread, it may help you on your way.
Collecting Vintage B&O is not a hobby, its a lifestyle.
If you run the BG without the aluminum platter, the belt will come off.
Ok thanks,
What about the belt drive wheel and the adjustment knob below? Any ideas why these appear to be loose, and how do you tighten it up to stop it moving around?
If you read my thread, you would know how to take it off, the drive mechanism has to move nearly freely horizontally, there is a spring tension one way as far as I remember.
To get the platter of, remove the small gear at the end of the flywheel shaft.
Thanks Søren... I have read your posts again and again but remember i'm still new to all this so forgive me if it's taking a while to go in!
I've just had a first look 'under the bonnet' of my beogram 1202 and now have more questions! Mine also still has the envelope with wiring diagram, as well as the pink laquer on the screw heads in the base! So...
- How do you center the motor? - I've noticed that the turntable and lifting ring are off centre and in order to center them you need to turn the whole thing over and adjust the screws from the bottom. But how are you supposed to do this when the turntable is upside down with the transit screws in place?
I'm trying my best to understand the BG 1202 manual but it doesn't make much sense!
Motor Centering, this is wrong written, should be Drive Centering, the German version is correct.
Turn transport screws counter clock wise to stop
The only way to do it is, Belt and aluminum platter in place, check, turn the deck upright, keep some fingers on the platter so it doesn't come off.
To adjust center, loosen screws "A", not too much, just enough to be able to move plate "B", move plates B and check, checking, the deck has to stand level (a good table or desk will do), place upright, move plates, check, move, check and so on, when centered tighten screws A.
Forget what the manual says about height adjust, adjust the platter to 1mm over or same height as the deck cover plate, the same all around.
Platter height: Adjust with screws "C", same as before check, deck upright, adjust, check.
Dont forget to secure your tonearm with tape and take off your pickup
Make sure your belt is the correct type, if it comes from Axel you are OK, if from somewhere else, no guaranties.
Thanks, I'm glad you said about the manual being wrong as some of it didn't match up to the German version!
Also, when I convert it back to the DIN cable output... Am I ok using any 5 pin DIN cable, such as the one you get on an iPod to DIN lead or do I need to buy a special DIN cable with an earth?
The original cable has left right signal to pin 3 and 5, these wires has each a shield which goes to pin 2, these wires has a outer shield which is connected to the steel casing on the DIN 5 pin plug, As these are difficult to find over here, I have used a 5 strand cat.6 data transfer cable with no problems, using 2 strands for the earth (ground)
If using the Ipod, MP3 player cable you will have to attach an extra ground wire, it is essential to avoid HUM. Do not make your cable too long stay below 1 meter (3 feet), if longer you will loose signal.
Thanks Søren, your experience with these is really helpful!
Have you ever removed the wood trim from the sides of a 1202? Mine is a damaged and I was thinking about removing it completely and replacing if I can find one for spares? Just wondered if it was possible and how easy it is to remove and replace.
As far as I remember there are 4 small hexagonal screws, 1 in each corner, oh yes just found them on a pic, this frame should be repairable if not too broken, normally it will come loose in the corners, with Gorilla glue you can save a lot of things.
Turn the deck up side down, take out the 4 screws and you can lift the frame off, check that no wires or cables are fastened to the frame, upper left corner I see something
