Bob;
I was glad I found the solution and gladly posted the information. Yes the Citation III-X has the same exact discriminator transformer as does the F500X FM Tuner. There were a series of AM/FM Stereo receivers that Harmon-Kardon made that likely used the same discriminator parts too.
Today I went through a complete alignment using the instructions that came with the tuner kit. At one point the unit began to make static again and I suspect one of the IF transformers is giving trouble in the same way. If it becomes more consistent, I may be able to track down which stage is getting flaky and repair the IF transformer for it also. If and when that happens I will post the information here. For now it is operating normally though.
