Title: Bench test AM radio
Post by: Camaro Billy on March 01, 2008, 10:29:13 PM

I want to bench test my 69' AM  radio. I'm a little confused on what plugs in where.I made made some jumpers from some spade connectors that will plug in to each connector. I'm not sure what is the speaker ground and which is the power ground.Can anyone tell me what each connector is for ?
Thanks for any help.

The two tabs on the left looking at your picture are for the speaker and the two tabs on the right are the power and ground. Power to the plus side on the battery and Ground to the negative.

Don't forget to plug in an antennae. :)

Also, if you plan to play with it a bit, use an 8-10 ohm speaker.  The 4 ohm speakers commonly available will draw too much current and ruin your output transistor.

Thanks everyone. I hope I can get it working, I have a Custom Autosound radio in now, but they changed the judging criteria at the Nationals this year and I need to put my AM back in or loose some points.
