Why build a tube audio oscillator? Why not! <img src="https://s.w.org/images/core/emoji/17.0.2/72x72/1f609.png" alt="😉" class="wp-smiley" style="height: 1em; max-height: 1em;" />]]></description>

					<description><![CDATA[Note also in this oscillator, the frequency setting element is a pair of pots rather than a capacitor or PTO/inductor. The frequency stability is going to be terrible. remember, the Wien bridge only oscillates when gain is exactly at a certain figure. Commercial audio oscillators were of the heterodyne type until Dave and Bill figured out how to use a light bulb as a stabilizing element. This made them multimillionaires and built an electronic empire that lasted until the Broad Restructuring and the spinoff of Agilent.]]></description>

					<description><![CDATA[The 6SN7 is a highly desireable tube and should not be used frivolously. 

 Plus, why on earth would anyone build a tube audio oscillator when HP 200s and their clones are widely available, cheap, and superb? Coals to Newcastle and all that.]]></description>
