I built the Kits and Parts RF Amplifier. Unfortunately it didn't work.
I don't understand it. It's a simple enough circuit, there isn't anything to go wrong. Unfortunately I find these kit construction failures too demoralizing. I struggle with my vision and shaky hands just to build the board. Desoldering and faultfinding are beyond me at the moment. If I do discover the cause of the problem it's something really obvious that anyone with a normally functioning brain would spot. I think it is time for me to accept my limitations and stop attempting to do what I used to be able to do before my brain surgery. From now on if I can't buy what I want ready to go out of the box I'll just have to do without.
