I dont have this amp, so cant comment on it. However, I have the other 300B SET amp, ES30, from Raphaelite. IMO, it is very well built with great workmanship and parts, have been running it for about 10 months now with great satisfaction and fun with tube rolling. The only thing I dont quite like it are the 4 octal sockets for the 2 pairs of 6SN7, which I upgraded them with better sockets.
