"Black beauty" my 211 tube amp design

This is my latest tube amp design. The enclosure is satin black anodized aluminium with a weight of 26kg.

Output power is 17Wrms@8Ohm. Pre-amplifier stage and driver stage are 6SN7 with a anode choke to drive the 211 tube at 60mA current.

Please see some pictures of the design below. In the pictures I use a set of PSVANE tubes.
