Can anyone produce a better scan of this schematic? The text on this one is mostly unreadable. The SO160 domestic model has significant differences. Thanks.

I've recapped my console by reading the values from the old caps and replacing with the appropriate modern version.  

In all of the restorations that I've done, I've never seen a Grundig schematic that has a voltage listed on greater than 300V following the rectifier so when I measured 330V, I tried to check things to see what the possible issue was.

I replaced the rectifier and measured 270V at the DC output side with nothing connected to it.  As soon as I reconnected the rest of the electronics to the DC output side, the voltage jumps back to 330V.  

I have replaced a number of the tubes, but since I don't have the schematics, I am struggling to figure out where the problem is.  Any guidance of what to look at it appreciated!

I have a Grundig SO 160ua that I am working on for a friend.  I realized that the schematics listed for the SO 160 are not the same as for the SO 160ua, unless I'm doing something very wrong.

On the schematics for the 160, there is no EABC 80 tube and there's an EBF 89 but not an EF 89, as you can see from the tube location plan below.

Does anyone have the schematic or know what the difference is?
