Re: 6-gang FM stereo tuner heads
That diplexer is a jolly good thing to have after a diode ring mixer even in the final receiver. Getting a good very wideband matc at the input of an IF strip is usually overlooked. You want a good wide match to absorb ALL things coming out of the mixer. Any power on these frequencies will only cause more mischief it it gets back into the mixer. You want to terminate LO and RF leakage into the IF, and all their harmonics and intermods.
