Default RCA to Coax modulator schematics

Hello,

I am sure I am not the first one to ask, but I didn't find a
straightforward answer to this.

I DID search the web for this, but I only found some schematic
drawings on RF modulators, but the input on those is COLOR, LUM, AUDIO
rather than the expected AUDIO LEFT, AUDIO RIGHT, VIDEO. So I guess
they aren't what I need.
Please don't suggest buying one in RadioShack - I don't have
RadioSchack in my country (at least I am not aware of its presence on
our market). Or reading 300 books after which I will be able to think
up a schematic of my own. I need a practical fix to a practical
problem. It's a small town with no such devices on the shelves (I
tried to do special order, but to no avail). We do have the radio
parts market here, though, so with proper schematics I want to try to
produce the modulator on my own.

In case it matters, both the signal source device (DVD deck) and the
TV set are PAL.

Thank you for your input.
Alex.



Just purchase a replacement RF modulator, or pull one from ta dead VCR
or the like.
