If you have any problems understanding this, ask me, I'm german too some websites say that this Tube contains 2x EL95 Thank you for reviewing it!

This tube triode section gain seem to be too small for this application ! It need 30 or more due to when output loading with 32 Ohm. Output stage gain drop to 0.3 or less !

Use 6H30 , 2A3,300B can drive 32 Ohm Headphone to very high level & good sound. This circuit is for DIY only , not for commercial. It had pattern in China by me. Dew
