In Reply to: Your Top 3 Affordable Musical FM Tuners posted by JoeLA on August 22, 2006 at 09:14:14:
the stock FM-3 used ceramic PECs (Packaged Electronic Circuits) for FM de-emphasis, which roll of the treble (often down about 4-5 dB at 10 kHz). David Berning published a modified circuit in Audio Amateur magazine many years ago which was within 0.5 dB at 10 kHz, which makes this a very good sounding tuner (Berning compared it to a Marantz 10B!) for very little money.
