RF Modulator for vintage TVs.

I believe the coils are as I have labeled them.
THe RF coils are spiked to adjust to channel 3 and 4 and then flooded with glue to hold them in place.

If you use that clean up the metal contacts of the RCA jacks, they are quite corroded.

I found that out already lol. And there is one hell of an audio buzz.

The "interference" on my CTC38 turned out to be an intermittent 300 ohm to 75 ohm matching transformer - just like yours, go figure!

Can't wait to see how the B-T works though... good can always be better.

I've had a bunch of those rf modulators over the years and they always seem to be a crap-shoot on how well they work.
My choice method for a direct wired connection to a tv has always been a vcr, especially mid 90's and earlier.
The B/T modulators do seem nice though, that's for sure. I would like to get one sometime as I have heard that they have a decent transmitting range.
