**BUG** Concise problem statement: The Speaker component should be 8 Ohms. The use of the omega character reduces this to a very low value (not sure what). Steps to reproduce bug: 1. Run sim. Note that output is a few volts pk-pk. 2. Delete Rspkr1 and replace by Speaker from EasyEDA Libs. 3. Re-run sim. Note that output is reduced to much smaller swing. 4. Delete Omega character. Re-run sim. Note that output returns to a few volts pk-pk. **Solution: remove Omega character from Speaker component value.** Url: https://easyeda.com/project_view_2x30W-EL34-tube-amplifier_rpjBvM4mg.htm Browser:Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/33.0.1750.152 Safari/537.36
