I'm sure Guy 13 can buy the $6 amp in HK for much less than that. Group buy anyone?
How are you powering it? Some detail if possible. I see the 12v leads......??ThanksJon
Try 4-6 output filter caps in parallel. But put them next to the amplifier. Use FM's, and any value will probably fine around 800-2200uf. They'll stay mostly charged, and your power supply is plenty big enough.Trust me, it's nice Then put a Felix in front of the SMPS. You're going to be very pleased once the volume pot is out.
A Felix is a AC power filter/conditioner. It is basically 6 caps and a Common Mode Choke, with three caps on either side of the choke. The caps are different values, to provide filtering over a larger frequency range.There is a long thread on it here somewhere, probably the DIY section.So you added $25-30 in caps to your $6 chip amp?BTW, I am not criticizing, I do stuff like that all the time, but you no longer have a $6 amp. Even when you factor in your mods, and the PS you need to add, still sounds like high bang for the buck.Randy
What size (form factor) is the diode on it?
