I've some questions on LM1875 amps.
1>>>> http://sound.westhost.com/project72.htm , here the link to sound westhost project using the chip.
, niw see there has only two 1Amp fuse in both rails, now for my purpose, I'll use it as a 15 watt Centre channel Amp. Accoarding to the datasheet it'll gimme the 15/18W RMS at +/- 20V. So how much current will draw the circuit?
can I use the same 1Amp fuse.
And can I use a 150VA trafo for that?
Again, I never made a PCB of the 1875 amp. I made it in a veroboard.
now I heard that there is a issue with the amp if some capacitor or resistor not placed near the IC. is ya true?
my veroboard layout given below.

now, go below the website http://sound.westhost.com/project72.htm, you'll see a power supply design. I wonder there is no any regulator, only two 10,ooo mfd caps, will it be sufficient for 1875?
