The opamps are all surface mounted so it's a bit difficult.
I'll look into the 1642.
I think there's room for polypropylene caps all over. The pins just need to be manipulated.
Thank you.
How important is it to use genuine Texas Instruments?
Genuines are too expensive for me. It's $8 a piece.

Strange indeed. Do you have a schematic showing the LED controller plus its supply?
The LEDs are controlled by a B1443N.

Less expensive (about 1/2) but almost the same performance are the OPA1652s--just half as fast (10 vs 20 V/uSec Slew Rate).The opamps are all surface mounted so it's a bit difficult.

Still $42 including shipping ($25). I have to think about it.
Which are more prominent, opamps or caps?

I think the opamps will make more difference

That's a good offer! Thank you dotneck.
Too bad I have to split the opamps in two shipments. Tax free limit is $13.
Does this free shipping offer only last today or is it standard?

There seem to be quite a disagreement on how to do it.YouTube has several tutorials for desoldering surface-mount ICs.
I have settled on a blob of solder along each rail and tweezers.
