hello..
i took apart a busted ihome..
there is a little low wattage 2ch audio amp..
does this chip look like a easy canidate for a diy amp?
1-7.5w output

i have experience making a headphone amplifier by following the Cmoy pocket amplifer.
can anybody tell without thinking too hard if this will be much harder than building a simple headphone amp from a opamp?

why on earth would you use that device?
No harder, but certainly far less satisfying sonically going by the fact sheet...

well i didnt pick it for quality.. simply wanted to use it because the alternative use is throwing it in the trash...
can you tell me please what on the spec sheet lets you know the sonic potential of the amp?
that way in the future i know which amps are better canidates?

thank you!
yea 10% is pretty high i usually see about 00.5THD on alot of things
is there a thread around here that has links to reccomended amplifiers or guides?
thanks guys

go to chip amps forum here. Look at a lm1875 for a real cheap and satisfying first gig. Good luck!
hello again guys.
well im trying to use the audio transistors that i pulled from other things before i threw them away..
this is mostly for learning.
i have two 2SK2645-01MR - N-channel MOS-FET
with the origional heatsinks for them. i dont remember what i pulled these from..
would these be better canidates?
here is the datasheet..
2SK2645-01MR pdf, 2SK2645-01MR description, 2SK2645-01MR datasheets, 2SK2645-01MR view ::: ALLDATASHEET :::
looks like maybe 50w peak?
