EL2003CN mono input buffer replacement for Music Labs Power amp

[Depaj]

Hi!
I came across an EL2003CN by élantec that has gone bad. It's a monolithic unity gain input buffer in a music labs ML825 power amp. It has high offset and goes crazy when heated up even just by putting my finger on it. It has a kind of strange pinout and is rated for 100mA of output with a slew rate of 1200V/µS. Does anyone know of a suitable replacement (the full datasheet is accessible on alldatasheet) ?

Electrically OPA633 might work but its pinout isn't the same, it follows the EL2033 pinout.

First of all, maybe he's not the problem.

I switched it with the one from the other channel and the problem went with it.
The tracks look really fragile, if possible I would love not having to move things around too much to adapt to a new pinout but of course if this is the only way...

Given PCBs are so quick to turn around and affordable these days, perhaps you could whip up an adapter?

Both Taobao and Aliexpress are showing sellers of EL2003

There are quite a lot of them available on ebay as well but I'm not always keen on ordering from these sites, it would of course be a lot easier.

I think I'll go for the ones from the us 🙂

maybe a member here living in the USA can buy two and send them to you for a different cost
It's almost Christmas after all, a little help is good in this difficult time for everyone

Shipping is expensive for sure but I found one selling 5 pcs for the same price as the one, still in the US. It comes down to about 45$ for all 5, shipping and import taxes included, I don't know if anyone can top that although the gesture would be very much appreciated.
