The Philips FT-920 was a very useful tuner. It was both FM stereo and AM and had about 30 nonvolatile presets and good sensitivity. It's downfall was its audio output circuits. These consisted of one 25 cent surface mount transistor per channel. The result was another low-fi sounding tuner.
Our fix was pretty easy - - - a complete new AVA audio circuit, with its own self contained power supply. Our audio circuits evolved over the years from the original Omega series to the current Insight Plus designs. We can still upgrade an older good working FT-920, either an original or with our older circuits.
However the best tuner we did, and one I still use here, is our Super Tuner Two circuits, all new boards and all, for a Dyna FM-5 tuner. We made major improvements in these in recent years by replacing all of the unity gain current buffers with LME49600 super buffers. These are kind of a necessary kludge into our circuit boards, which were designed for 8 or 10 pin current buffers, while the LME49600 is a 5 pin surface mount device. However the sonic quality of the Super Tuner Two with LME49600s is pretty amazing.
Unfortunately the Dyna FM-5 tuners are very old now and not many are in good working order (the front end assembly is not replaceable or repairable) often dies and then the tuner is done for. Our replacement board set is long out of production so we can't do the upgrades any more.
But I won't part with mine. You would have to hear this one here to believe it.
