I got the kit today with the proper tool. Unfortunately, I can't get the FM aligned as there's no response in trying to do so. I hooked up the generator to the points indicated in the instructions on the 12AU6 tube(grid), put the VTVM on the proper point and hooked the ground to chassis and tried tweaking one of the first IF's and turned it several turns back and fourth but the VTVM didn't respond. The needle didn't move. I had it set on the -DC scale since the tubes grid is negative but nothing. I then tried setting the VTVM to what's called the "zero center indication" buy setting the needle right on the 0 in the +0- setting. Still no response. Any ideas what's wrong? Sort of aggravating when you've waited for the right tool to get here and then no response for FM tuning.
