This board is very based on the datasheet of the TDAs like mine one. The gain on your board is not optimized, that 1k ressistor, that is for gain, can be used, but its better always check the datasheets to use the right one, witch is, for tda2050 for instance, 680R, with 1k you will lose for about 2W of the IC.

You can use any circuit based on tl072 or ne5532 with tone control on the input of this amplifier.
