Hi Sandy,
No, JVC never made a TM-P3 with a built-in tuner, neither for the NTSC market, nor for PAL.
It's original intent was to be a luxury consumer field monitor in the days of the standalone camera + umbilical cord to a VHS shoulder carried recorder. Cost a fortune when new, sort of US $700.00
Seems LEADER seized the opportunity to incorporate a ready made consumer product for a pro application and sold thousands of them.
If you query JVC TM-P3 by itself, the prices are often quite more expensive standalone than packaged with the cute LEADER scope, go figure!

You can make a "use anywhere" TV with an ATSC tuner or a Blonder-Tongue modulator re-broadcasting the NTSC A/V out of an ATSC tuner, then using a compact NTSC tuner such as the IT'S TB-100 to feed the JVC around the house. The IT'S tuner is no bigger than your hand.
