Hi VLF, This evening i received ZEVS for the first time in the garden :-) I used nearly the same circuit than in my email below. However, i found that the J310 was damaged! Remembers me on the old di
Hi Stefan, The 82 Hz signal looks good... you may even catch a glimpse of "DX" from the US and their 60 Hz mains with that setup. It's several dB down on ZEVS but sometimes good copy here, on an acti
Thanks Wolf, Yes, a good idea. I will try to catch it :-) But how do i know that it is the US mains instead of a 60 Hz monitor? Is the 60 Hz from the mains more stable? I will work on the circuit and
