I had the good fortune to purchase this unit, along with a Beogram 1600 turntable today.  I spent much of the evening getting acquainted with the Beomaster.

As far as I can tell, everything is working. I plan to get some 2-pin DIN speaker connectors and a PAL antenna connector adapter.  I also plan to replace the female RCA connectors on one of the DIN to RCA cables as the casings are brittle and one actually cracked.

For some odd reason, the previous owner cut the power cables on both the 1900 and the 1600, then reconnected the cut wires back on with some kind of heavy white tape.  This is something I want to correct.  When I opened up the 1900, I could not see where the power cord connects and I did not want to disassemble things any further than I did before seeking help in this forum.

So, my first question is, can someone help me with this - what else do I need to remove to get to where the power cord connects to the unit.  If I must I will clip the wires inside the unit, solder on a new power cord to it and cover it with shrink tubing.  I'm no technician, but I can solder and would much prefer to attach a new power cord wherever it needs to be soldered on.

The other question I have, is does anyone have a source for rubber feet for this unit?  It's simple enough to stick on some feet, but if someone knows where I can get rubber feet that will pop into the 1900's feet holes, I'd rather do that.  The feet on this one are very brittle and literally breaking.

I will probably be posting some questions regarding the 1600 turntable after I check it out.  It definitely spins, but the tonearm does not lift off enough.  The good news is the MMC 20EN appears to have a lot of life left on it.  I know from past experience that the cost of replacement stylii for the B&O turntables is very high, so I was pleased to see that.

thank you in advance for any responses.

Hello Eidling,

Welcome to Beoworld! Great to be able to say that for the first time and maybe help you. I have a post in Workbench below yours called "Beomaster 1900 Restoration Questions" so can help you a bit. There are 4 screws on the back panel and 5 screws on the base plate that you should remove to get at the bottom of the 1900. The photograph above is my 1900, that I just did a bulb and capacitor replacement on it but will have to disassemble it again to find a fault in the left channel which is not working.

Regarding the rubber feet you are looking for to replace the original I did a lot of looking on the internet and could not find small ones that would work other than the stick on kind. I was hoping to find something with a screw that could be secured from the back of the bottom plate. You may have better luck. The ones I have are the stick on kind we can find in the USA almost anywhere, mine came from Radio Shack but Home Depot probably has them.

If you need any bulbs are interested in doing a capacitor kit replacement, Martin on this forum is a great source. You can find his posts with the name Dillen used as well. Hope this is helpful, I am a real novice with electronics but there are many really technically experienced B & O people on this site that can help you with the more difficult questions.

John

Hello John and thank you!  I went ahead and took things apart.  Unfortunately, in the process of soldering a new power wire onto the mains switch, one of the terminals on the switch broke.

I did write Killen to see if he might have a switch for me.  I hope I can find one somewhere.
Today I went even further and took the switch apart.  That gave me some hope that I could repair the switch, however I now need help with a couple of other things:
1.  I need to find a replacement for the terminal that broke. There are 2 types of terminal bottoms.  If I can't, I may be able to solder a new piece to what is left and make something functional, but I hope it does not come to that.
2.  I know how to put most of the switch together, but am not sure about the two pieces of metal that connect or disconnect the terminals.
This shows the underside of the plastic switch.  There is a tiny spring that runs between the two small white plastic end caps:
I thought this last shot might help someone show me where those two pieces should go.
If anyone has a source for this switch please let me know. I know it is identified as the Mains switch, part #7450023.  Also, if anyone has a shot of the inside of the switch as it should be, please send it to me.
Many thanks in advance for any help anyone can offer!
