    I've come across what appears to be a rare bird, a Phase Linear 5000 Series Two tuner. It's got issues receiving stereo.

    While I can find mention of this model on the net, I've not been able to find a manual for it. I don't have a problem paying for one; I came from the old school where that was the norm. Can anyone here help?

    Here's a pic of the tuner 20180103_065034.jpg

    Well, I was able to resolve the issue with this tuner by looking at the data sheets for the IC's in it. 19 kHz was way off; once I got that set the stereo issue was resolved.

    Hello. I just picked up one of these tuners and it is also having an issue receiving stereo. The stereo light comes on when switching between channels but will not lock on once it is on a channel. Is this a difficult repair? I'd like to try to do it myself.

    IIRC made by Pioneer - possible source for service information.

    Stereo problem - sounds like clean and adjust VCO trimmer.
