Not open for further replies.
guys, I have been wondering, do I isolate the input signal ground from the power ground? I shared ground for everything.
 
correction on the offset voltage I measured 20vdc on output without signal!....yikes...Also strange is that the direction of cone push is sometimes opposite, either in or out when powering up.
