Hi, I'm trying to adjust the FM tuning on my 4020A and it appears to be off by ~1-2Mhz. I don't have an oscilliscope or anything to verify the tuning. It's a bit difficult to tell by the service manual which adjustment I need to make (I was going to use by trial and error, using a good station signal) to try to correct this. According to the SN#, I have the new version. Thanks for your help
