A simple sine wave generator with a 741 opamp. Of course you don't need a rotary switch when you only have to generate 1 frequency, for instance for the 1-100 milliHenry inductance meter schematic (on my channel). Upload in relation to my book "schematics 2, audio amplifiers and loudspeaker boxes". You can find it on the website of LULU (link in this textbox).
I published a good 2 transistor Wien Bridge sine wave generator working between 20 Hertz and 19,2 KHz on 7 may 2013 on the Lulu website. Title: "two transistor sine wave oscillator 20 Hz-19,2 KHz", author Ko Tilman (link in this textbox).
Many videos hat I have published on You Tube can be found via my Channel Trailer: Link is

In thematic order you can find these video’s under the “comments” section.
Important: to find all the links to the (+/-700) video’s on my YT Channel, select, in the comments section, “NEWEST FIRST”
My books about electronics are available via the website from “Lulu”, search for author “Ko Tilman” there.

There is an important video via which you can buy a document where I give links to many of my video’s, published between 2010 and 2018.

My books are also available via Barnes and Noble and via Amazon.
Regarding all my video’s: I constantly keep them actual, so the original video’s with the most recent information are always on YouTube. That is the source, and search there. When my video’s are reproduced or re-edited on other websites/channels you can not (!) be sure about the original content (=really working electronics) and important adaptations to the circuits.
Be aware of that, I saw on the internet my circuits reproduced in a poor or even not proper way. I can not help that, sorry. Update 1 June 2019.
