Title: Simple AM Transmitter with a MC1496 IC? Remember these? And, AN/NE 612?

https://blog.zoftko.com/posts/simple-am-transmitter-mc1496/    Gees... Just about every AM / SSB CB, and a few QRP HF transceivers, had these as a main-stay from the late 1970's, through the 1980. I have several rigs that have the 1496, and we even spent a day in college talking about this IC. Still, a vary viable AM option. The other IC that came to mind around that time was the once for a Balanced Modulator.
UPDATE: Oh duh!!!! That MC1496P is the Balanced Modulator. Not a bad price either, and free INFO downloads.  https://www.jameco.com/z/MC1496P-National-Semiconductor-IC-MC1496P-Balanced-Modulator-and-Demodulator-14-pin-DIP_23211.html?srsltid=AfmBOoq8v7oi5cVicMy_rM61U19gmT0REBdaNlp7QQ6ch4wV2rtw1w5U     See what happens when coffee hasn't kicked-in fully yet?

ADDITIONAL: Boomer found this as well.  https://dk7ih.de/mixer-comparison-ne612-vs-an612/    So, neat!!!
