Which STK-0050 Is Best STK-0050? I Don't Know!

Need tools? Here's a video showing what I use (with links!): https://youtu.be/MLK649c1_fM This Kenwood KR-5010 showed up with a blown STK-0050 power pack that was causing a direct short in the receiver. I bought two things: the cheapest eBay replacement I could find, and the open source replacement made by an audiokarma member. Then I put each option "through its paces" and took note of what happened.
