That looks really tidy, nice one. How did you get it to 750 mA rather than the 600?
Cheers Andy

Hi Ollie
Just need to sort a date, Ill probably have to stay over in a hotel, its a long way up from near Brighton !!!

It's just down to the value of resistor in the first half of the shunt regulator, provided you meet the following criteria:
1) The FETs are adequately heatsinked,
2) The rectifiers are the larger current ones specified in the BOM,
3) The mains transformer is adequately rated. A 100VA will just do 1.2A, anything below this is fine.
Hi Andy, There are 2 resistors in the picture just below the bank of 4 caps (brown) you need to change the values of these. As standard the board runs at 60 to 70mA with the supplied resistors, just change the values !!
If you want to further improve the sound change the quality of the 8 resistors around the orange relay for higher quality resistors .
Eg. Audio Note or similar.
To be honest the first build I did was only running at 200mA but sounded Dam Good !!!!
