seaching schematic for Universum SK992 ( Quelle ) (Gezocht)

Hello to all tube and radiofreaks,
2 days ago I found on a fleamarket a very nice radio / TV device.

http://www.radiomuseum.org/r/quelle_fernseh_rundfunk_kombina.html

After seaching for electrical damages I used my variable isolation transformer to run it the first time
very carefully.
The radio part works very well, so I switched to the TV part.
There was a horizontel line on the screen with a height of 5 cm. I think it could be a problem with the deflection.
After I ran the TV about half an hour I noticed an electrolytic capacitor which began to get bigger!!!
After replacing 2 caps I was able to recieve a bad pic ( I think there are some additional deflection problems). After the TV was running some further time, the pic and sound disappeared and the only I can see on the screen is something like snow falling.
I hope that nothing really serious is damaged.
I'll replace all the electrolytic caps and after this I'll make a new try to run it.
The problem is that I don't own a schematic so it's impossible for me to find additional mistakes
after I replaced the electrolytic caps.
It would be very nice if someone would be able to send me a schematic.

kind regards fromGermany

Didi
