Hello Mike!

In deed it seems to be a more serious problem. Ehen switches on, in the 
display is shown "1.8 50 01", but theres no reaction to key-hits or 
pressed buttons, not even to the switches on the back. Only when VR1 is 
turned, the machine awakes and starts to make weird noises like 
uncontrolled key-hits and noise with cut off-modulations. This is why I 
wonder if the problem might be caused by any dead transistors Q1, Q2 or 
maybe Q18.
