Newbie- test equiptment for am receivers ?
 

What inexpensive test equiptment can I use to
troubleshoot and repair old am ( broadcastband)transistor radios?
I have seen a Velleman Signal generator kit $11, output 1Khz fixed,
0-100mVrms, and CKIT has a signal injector kit$6 and an Audio signal
tracer kit$8.I have only a digital voltage meter and a homemade audio
output level indicator. My experience is limited to building a few
kits etc.
Your help will be really appreciated.
