EXPIRED DIY tube preamplifier (Rogue Ninety-Nine circuit)

[MarkLSF]

Further Information: 

 

This is a preamp made by myself, it uses four 6sn7 valves. The sound of this preamp has the characteristic of 6sn7, dynamic, full-bodied and energetic. I think it is suitable for classical music. Volume control is by a step attenuator.

Looks like nice build and neat workmanship. Is the circuit based on anything in particular?
