How many pins in the din connection for my 1900 receiver when attaching a phono turntable?
Its a 5 pin DIN, left right and sound common ground, thats 3 pins, dont forget chassis ground to steel casing
Collecting Vintage B&O is not a hobby, its a lifestyle.
2=common ground, 3 left, 5 right, forget 6/7, chassis ground solder to casing.
Thanks so very much.....helpful for me to buy a cord missing for my recently purchased rx 2 turntable
Thanks again....I have seven pieces of B/O equipment. Fits in with my passion for modern design and architecture.....

If you intend to or are doing repairs and adjustment on your equipment, you have come to the right place, lots of help to get.
And for silver and gold members there are repair manuals available, for nearly all B&O equipment.
Welcome to the forum

I do have another 1900 and the left channel for sound does not work on either 1 or 2 speaker options......the schematic for repair looked very complicated to trace......I live in small Indiana city and do not know how or where to find any help......any suggestions will be very appreciated
Thanks
Dead and/or intermittent channels in Beomaster 1900 and 2400 are often caused by brokenbalance potentiometers. New parts are no longer available but they are usually repairable.

If you do a search on the forum, also the archived forum, you will find a lot of information.
The 1900 as well as the 2400 are, because of their age, prone to bad electrolytic capacitors, lamps and trimmers (potentiometers), the slide potentiometers for treble,bass and balance also may need an overhaul. I made my 2400 with parts from Martin (Dillen on this forum) look here that repair lasted 6 month and then I got problems again, look here, and that is what can happen with these wonderful old bastards.
I have since done some more repairments, and what I have learned is: When you open up a unit and start repairing, do it all and do more than just eliminate the actual failure, if changing electrolytic caps, do them all, power supply to amps, if one output transistor is bad, change all of them and so on. The first thing I do is to clean everything, Look here, that one is the worst I ever did. Clean everything, all connections, plugs and jacks, and then start changing parts. If you know a little about electronics and can use a soldering iron, you can do it.
Martin sells cap and lamps kit, that comes with descriptions on how to do it, he also can provide several parts, used or news depending of what you need.
Making a list of caps and lamps, and finding a supplier is a hack of a job, Martin makes this easy and to good prices.
Following the drawings can be a problem, but if you split it up into small parts, and just concentrate on the area you are working on at the moment, it is not that hard.
And when you run into troubles the forum will help out, there are specialist who loves solving problems, they dont just tell what to, they also explains why.
So if you like this kind of time consuming hobby, get on with it, and dont hesitate asking, we are here to help. There are no stupid questions, only stupid people who dont want to answer them.
