RE: 6B4G Single End amp in a new suit ?

It appears from the circuit that the 6B4G grid bias is positive, but everything else (including that the tube does not immediately melt down!) indicates that it must be negative. So, while I'm confident the circuit is mis-drawn, I am not confident aboout what the actual circuit really is.

Michael Samra, the 300v/50mA operating point is a good one; I use it in the Bottlehead Paramour/Stereomour - the basic design is 17 years old now and has never been a problem that I know of. The important thing is to use a higher load impedance - I use 4000 ohms. I don't know what impedance is used in this circuit.
