There are 2 class D amplifier boards up for sale both purchased from inkocean...
ITEM 1 -
Up for sale is one of my favorites
The Sinilink XY-T00L class D amp with 200w(100wx2) sound output along with Bass Treble and volume knobs
(power supply not included)
This has fantastic audio quality...
I remember registering it for extended warrantee but I have no emails from Zotac confirming it. I've emailed them now to get an update.
Let's assume it has only 6 months warrantee left.
EDIT: Got an update, it is 5 years from 26th Oct 2020...
