I've been building my radios and stuff since I was licensed in 1991 (and I built lots of audio gear before that), and in the ham radio literature I had access to in those early days, the 40673 and similar devices appeared frequently--and it always frustrated me, because they were seemingly hard to find and expensive--I've since acquired two or three similar devices, and I've been thinking about trying some of those old circuits that I used to avoid because of the 40673's (haven't done it yet). But your comment about tying the gates together made me wonder whether other circuits I've seen that use a dual-gate MOSFET with the gates tied together could work with a regular MOSFET. I know there is a lot I don't understand about this, but if there is a simple answer, or a direction in which you can point me for more education in the matter, I'm all ears.<br /><br />Blessings, my friends, and 73--Doug (AA0MS)Doug, AAØMShttps://www.blogger.com/profile/09599674209018352853noreply@blogger.comtag:blogger.com,1999:blog-7590176649168185428.post-77884409303087665222017-03-22T12:08:46.545-04:002017-03-22T12:08:46.545-04:00tnx es 73tnx es 73Bill W5EPWnoreply@blogger.comtag:blogger.com,1999:blog-7590176649168185428.post-82356115244428549412017-03-21T12:15:18.728-04:002017-03-21T12:15:18.728-04:00Here you go:
