It's not hard to build a SE point to point wired amp but, you can also simply things by getting one of the Clementine circuit boards from diytube. In this amplifier, the 1k resistors in the driver stage can be bypassed by 50 uF capacitors to increase overall sensitivity. Joppa's Rule states that for "typical" listening spaces an amp/speaker combination should be capable of producing 102 dB. SPL peaks at a 1 M. The data sheet indicates that at low bias voltages and lower B+ the screen current can get rather high. While doing that project, I thought that I should really design an entirely new 6V6 SE design specifically targeted at someone doing their first major tube amp build. See full list on diyaudioprojects. The 6V6 datasheet has an operating point that's: 250VP 250VS 12. Have built it myself for my daughter out of parts lying around and small Edcor transformers.
