Default Tedelex PSU debug

Hey there busy pirating parts from an old tedelex amp, I want to take some of the modules inside but can not quite work out the voltages needed to drive them... I have mapped out the psu as best I could... takes quite a bit of concentration traceing all those traces (lol).

Can someone tell me what the voltages at x and Y will be?
Erm, please!

the zeners are marked 880X

Output voltage will be zener voltage plus one diode drop, but I have never seen such a zener diode numbering system.
