Not to dump on anyones product in particular but please beware tube amplifiers which have the tube sockets soldered directly to a circuit board. It is not a reliable construction over the long term especially for those who enjoy tube rolling. Heat and the mechanical action of pulling and pushing on tubes as you change them can crack solder joints and circuit board traces.
There are some very high cost amps with this construction and I am always surprised they choose this method. I would always prefer a product with tube sockets mounted to the chassis and then flying leads to a circuit board or even better true point to point wiring.
