WTB: STK043 stereo amplifier chip

[gilwe]

I'd love to buy if any of you have a spare one...

This is for fixing a Fisher RC-1022 receiver. Thanks !

available

in athens greece
for the astronomical figure of 36 euros each ( !!!!!! )

no web page you have to call the company +302108621500
mr panagiotis

they probably ship them anywere

they have also 5 pcs available

Thanks !

I've seem them going from as low as 13$,
but no shipping to the location where I'm at...

The price of them is astronomical!

Personally, I'd see about retrofitting some small amp circuit in there. Something with TIP142/147 darlingtons for example.

There might also be other kinds of STK that you can use that are pin compatible, more readily available and cheaper.

i agree too

the price for a thing like that is very expensive ( on the other hand i dont like stk sound any way)
..... depainting on the rail voltage i would be very happy to locate inside a couple of very happily P3A borads ....

you may wana check this on esp pages .....

Actually now I come to think about it, what I would do is retrofit some LM3886s into it. They are small compared to the STK and you could probably do a point-to-point wiring if you don't feel like doing a small PCB.

Also, they will sound better - the STK-043 datasheet says 20W output power into an 8 ohm load at 1KHz has a THD of 0.4%! The LM3886 is far superior in this regard.

The STK043 is a dual power amplifier.

You could try a LM4780, or hack it up for two LM3886.

Yeah I meant to say 2xLM3886. You'd easily fit 2 LM3886 chips in the same place as the STK, as theyre quite big. LM4780 would work too but the pin spacing is a bit of a pain.
