My good friend Dale, WB8WOJ, sent me a care package with all the parts for this little amp. I used NB6M's schematic to build it.

Here is the link to Norcal's Miniboots page.

I use this amp to boost the signal of my W7EL 1.5w rig, when conditions aren't so good.

The output was adjusted for 10 watts (6x the output of the rig). At this power level, the heatsink gets warm, but not to hot to hold.

Picking out the most suitable heat sink from what I have on hand.

The rf sensing comes from the small circuit board behind.

There were a few component changes, you might see, if you're looking closely.
