Hmmmm I wonder if I have that one??

I found 2 RF modulators @ salvation army and 1 of them has what you describe!

Cat # PH61159 (PH - Philips??)

On the back its got

RF in/out Audio L/R VIDEO IN and an S-video jack.....

On the front

A RED light (MOD. ON) and a channel 3 or 4 switch......

Could be the same beast in disguise...

15-1214 (Read the date code label on the actual unit, this was changed to "15-1214A" sometime in 2004 but the part number and UPC are the same, so one that says 8A02 or 04A03 is just fine, but 02A05 is a no go. (last two digita are year of manufacture.)
15-1215 (Same as above, but this one has 4 sets of inputs.)

15-1244 might also work, it was the "not-stereo" version (no S-video, and the L and R channels are just summed internally.) again though look for production runs after 1999 but before 2004.

There is no date code on it..........

I looked @ the back and nothing..........

Here is what it looks like

Sometimes comparing the FCC ID numbers will help clarify things.

Chip

Catalog number on the stereo one is 15-2525. It has "stereo" written on the case.

Interesting. This modulator I have that I bought over at the Radio Shack Clearance Center (...in FW off of Northside Drive and I-35W, used to go there every 2nd or 3rd Saturday don't remember exactly at 7 AM lined up and waiting...) back in 2000-2001 is an early possibility they probably cleared out, too expensive. I bought 3 of these discontinued items for $30 ea. No single chip wonder here like in their later model in Chris Cuff's video. Notice the separate DBX encoder chip to make it exactly right. VR2 I marked on the board back then, that's the video level. Was low out of the box.

Too bad that was not there when I was a kid ... that is walking distance of
my home! And my mother was, for a time, Mr. Tandy's receptionist.

It was a near ritual to go over there every month to see what they would have. Ham radio guys and others would set up to sell stuff in in the parking lot an hour or so before 7 then the big rush to get to the goodies first.

Anyway I guess I should hook up this modulator someday, run a macro'd tape through it and see if it gets striped out. Never checked for that. I used it with my old big dish C-Ku band satellite receiver to send Ch 3 in stereo to a couple of TVs in other rooms.

Hey, I have one of those. I got it years ago. I thought the (then) company had gone out of business, because the link I posted in a website article stopped working long ago. Maybe they changed distributors or something. No idea what's inside, but it gets the job done.
