Has anyone here built a Slone Amp or a Tigersaurus?

[Mitchel]

Hello Mitchel,

I am toying with the idea of building the v4 of the Optimos amp that you crafted PCBs. Do you have a BOM that you could share?

I am particularly interested in knowing where you bought those T0-220 heatsinks.

Hello, Carl. The BOM is attached. View attachment Optimos-BOM.zip

Those heatsinks are actually made from 2 identical pieces mounted back to back. They are pretty easy to find here in Brazil:

There are equivalents to those shown. Fischer SK-145 and Aavid-Thermalloy MQ50 will do at a pinch but they are both wider than those shown on the silkscreen.
