WTB : Pair of LM4780 from genuine source

[pinnocchio]

Looking to buy two LM4780TA/NOPB (previously bought from a genuine trusted source like digikey or Mouser. No eBay, Aliexpress or the likes)

Thanks
Do

Do -

Maybe LM4780 IC | Chipamp Electronics ?

I might even have the unbuilt amp kit from chipamp in the basement, and I'd be happy to sell you the chips, if they're the right ones.

Hi Tubesguy,

If you do have 2 LM4780 I would gladly buy the ICs. The NOPB is just the part without lead but I don't really mind if they're NOPB or not for as long as they're genuine.

Thanks

My bad. I've had these for even longer than I'd thought, and they're the old 1875 version.

 

[pinnocchio]

No problem! Those 1875 are actually pretty good btw.

Thanks
Do

As you may know LM4780 are on the off ramp to obsolescence. Both Mouser and Digi-Key now require 45 minimum quantity. I bought 2 for a Parallel 86 + Modulus 86 4 channel build to power my LXminis about 2 weeks ago from Newark, who had a 1 minimum but the price was a bit over $15!

Newark/Farnell has them in stock both in the US and UK. They're an official TI distributor.

I'll buy them from TPA audio, they have some in the parts bin and the shipping is very respectable, unlike the 25$ shipping tag of Newark Canada.

Tom, since the LM4780 is going disco, are you planning to modify your Parallel86 to a dual LM3886? It probably would also help for heat dissipation.

Thanks

Thanks everyone! I ended up buying a pair from TwistedPearAudio, thanks Brian!
