Yes. Of course, but let me finish the project, almost the front end.

Update: I found a breackage in the connection of one anode of the EZ81 and the traffo secondary causing lots of ripple at the output of the ECL82 voltage stabilizer. Then I shall see tomorrow if the baseline of the sweep osillogram is straight as it must be.
