Sorry for a probably basic question, I'm just getting into electronics. I'm learning as I go, but don't really know how to debug many problems.
I'm building the old Ladybird crystal set, as seen here:
**broken link removed**
I've replaced the OC71 transistor with an NTE 102A.
You build the radio in stages, and with the first transistor installed I can hear many stations and it sounds great. The next step has you go back and bias that first transistor by adding 33k and 150k resistors. As soon as I do this, I lose all station selectivity and it just becomes one big mess of a single station. Any help on how I can go about debugging this?
