On my last trip to TX I got my BG 1000 and a BM 1900 ( more in another thread). The BG 1000 is considered the first real B&O made BG. The BG 1000 has a sentimental value to me, it was the first ever B&O BG I have owned, I bought it new 1969 in Holstebro in DK together with a BM 1000 and a pair of Beovox 1000 , I owned this system for about 2 years and then sold it to buy a car. Last year I bought a BG and BM 1000 in DK, but my son fell in love with the BG and kept it there, now playing through a BG 1900 and Beovox P45s. So I brought the BM 1000 over here and had to look for a BG 1000 again. I am still looking for Beovox 1000, and one day they will be there too.
As I want the BG 1000 to perform perfectly I planned to take it apart completely check every single piece for wear and correct function. It came like this in a bad packing, but double boxed.
As you see a lot of damage to the acrylic cover and an ugly glue pad, probably someone had a cleaning or anti static brush glued on there.
It came just like this, no packing between cover and platter, the tonearm not secured to the stand, the cartridge in place, no tape to secure the cover to the base. As you see the 5 pin plug cut off and not there. The cable is white, I have until now only seen grey cables for BG signal cables.
Here the number and type, I think the type 5202 is an early version. The repair manual onsite is for later versions.
I bought this one on Ebay USA so I wonder now if I have a 50 Hz version or a converted to 60 Hz version. Maybe the 5202-1 type is the US version. I did not connect it to try, because I want to check everything first.
Bottom plate and power cable out.
Bottom plate off, looks clean, but as this is a VF version it should have a preamp inside, not so.
Where the preamp PCB should be inserted there is nothing and the connections are bridged, I checked the connectors and it looks OK.
Turned the deck around, and started dismantling from the top, pull off the insert for 7" records, keep on finger over the center hole to avoid the retaining ring to fly away to a never come back place, then with a pressure ring plier pull off the pressure ring. you can now take off the center plastic piece and the rubber mat. The speed selector and speed fine adjustment knobs comes off easily just pulling, mine speed selector knob came apart in 2 pieces, but a little glue will help there.
The platter comes off loosening 3 screws
Platter out
When you lift off the platter the drive belt comes off the platter, fumble a little and you can pull it off the drive pulley
Loosen the 4 screws and the the whole insert comes out, it is now time to pull off the the cartridge.
Wood frame out
Motor support, just to remember how the nylon pieces are fitted
Now desolder the 2 wires on the tonearm switch, disconnect all the other wires in the white connector, loosen 3 nuts on the motor support, use a pliers to lift off the spring loaded disks and pull out the motor with connected wires.
Loosen one grub screw holding the tonearm switch and pull it off take out operating shaft, take off the voltage switch.
The blade spring comes off by pulling it to middle of the rod, lift the rod a little and the spring can be pulled out sideways, then loosen the grub screw in the handle, pull out the rod from the lift lever and then from the lift handle.
All out
Desolder the wires coming from the tonearm, unhook the tracking weight spring, loosen the nut from the shaft and pull it off over the wires, take out the tonearm
Using the base plate as support pull out the small pin with a side cutter, keeping a finger on the spring doing it, loosen the nut and pull out the lift mechanism
Then I took off the bottom bearing, and found out that the bearing shaft has a screw securing the platter shaft through the recess in the the shaft, this means that you can get the complete platter off without taking off the top pieces (7" insert, plastic center, rubber mat and the 3 screws, easier when changing belt.
And here we are, a main cover ready to clean and paint. And thats how far I got yesterday with 3 hours job.
