Hi Andi, any joy with the scope pictures yet?

BEWARE that you will need to run the set through an isolating transformer as it is an AC/AC type before you attach the scope (there are other tricks but if you don't know what they are it's best not to!

You can also try injecting 6.3V 50 Hz from an old heater transformer into the op valve grid to see if that stage works (the art of coarse servicing!).
