Hi all,
It seems that I have solved my DC events, that triggered the e12 from time to time.
I tried to see what happened if using only one channel. So I removed the tube of one channel at a time. I tried all permutations of channel tube removed and tube. As a conclusion: one channel at a time was always working. But two channels at the same time generated those DC events. It could comme from a load problem on the power supplies.
So I went again through the initial setup sequence to check the voltages and idle currents. Not changed a lot, but had to adjust slightly the tail current of the input staage of one channel.
And now seems to work wothout DC events. Let's see over what happens the weeks...
Regards,
JM
