Some of the ones I’ve looked at online utilize a 567 chip and op-amp. I’ll give it a try. August 26, 2021 at 5:49 pm #20387 ChuckParticipant Built this little beast 5 years ago – works great. You need to match some components but it’s a pretty easy build. Chuck Author Posts Viewing 4 posts - 1 through 4 (of 4 total) You must be logged in to reply to this topic.
