Default Very simple high power single ended

see here

the new EL34 Parallel Single Ended - ver. 2

The project has some interesting features:

1) single ended design with medium-high power about 10w
2) class A1 operation to use the most linear area of output tubes
3) normal idle condition to have a long tube life time
4) Zout near to 1 ohm to have a good damping factor for a fast bass frequency on any kind of loudspeakers
5) simple design for any DIY with a low power supply voltage
6) it use only common tubes which are easy to find with most suppliers
