What do you think it's like with jFets or mixed? "Da geht erst richtig die Post ab".Hi...
I just received information that the OREAD PCBs have been shipped.
I assume that it will now take around 14 days, including customs, for the package to reach me.

thermal balance:
When I was working with the SUPRA some time ago and, for example, measuring the output voltage offset, I noticed an irregular but persistent +/- fluctuation around the zero point of a few 100µV. It took some time before I realized that I myself was the cause, namely my breath, which was passing over the circuit board and thereby irregularly affecting the temperature of the transistors. In a housing without air movement the “problem” disappears. When testing a board without a case, you can place a towel or something similar over it if necessary. It will probably be similar with the OREAD
Please reserve two boards for me, thank you very much - PN will follow.
