Two cheapo 10W led drivers, which I hacked (see previous post) to supply 1A current, just died. They make high frequency noise now. Checked components and found that output diode has failed. Diode is SR260, 2A shottky. I guess it's failed because of temperature inside driver enclosure. I made holes in second driver and it's failed too.
Replaced SR260 with 2x1N5819 in parallel, works for now, will test inside enclosure later.
