SP-10 sound like SP-10 ..... ^_^ , very laid back and musical but still running in. I use MIT cap and does not like it and I just change to kimber now and quite happy. The two large white caps are two big MIT 12U caps. I think you ask why I use two transformers ? Basically, SP-10 need quite a complicated power supply, 280V , 6.3V for the power supply tubes regulator and two independent 12.6V heater as one heater had to connect to high tension. and also 9V for the input selector. So I need two transformer to cope with it. SP-10 is famous for using a big 6L6 as tube stabilizer so you do need a lot of power supply.
Yes, i do, i normally there during the weekend. You buy a lot of kit! Their marantz 7 is actually quite good even though the circuit is a little bit different than the original one. Did you bought the tube stabilizer circuit too ?, the attached photo is what I have build from their circuit and of course it is a separate power supply for marantz 7
