Yeah, nevermind, I didn't notice you posted the component list in the 1st page and that yours wasn't PAL, doh!uglybuddy6 wrote:I used a 1N4741A which is 11V and 1W . For PAL I think a 1N4746A should work that is 18W. I bought mine through amazon it came in a pack like this. https://www.amazon.com/Chanzon-Assorted ... 07BTKVRG8/
So you're applying at least 11V to the telephone line instead of the strandard 9V?
I bought 9,1V 1,3W zener diodes as I'll try a different approach. I'll try to build a LVI with 9V and 18V switch, as I have both NTSC and PAL modems.
