I'm looking to open the clarifier on my trc 449 but can seem to find the resister and diode to cut . Anyone have more info or a board layout?

To make the clarifier work has a shift in RX and TX you need to unsolder R119 which is connected to D32, the end you need to unsolder is the other end known as the hot end when you have unsolder it connect the hot end to Pin 1 of IC6 and remove D30. That it all done.

Can you tell me about where on the board to find the R 119?

Sorry I do not know as it as been over 15 year?s sense I last work on one, but if you flow the wires from the clarifier control you will come across it. It is also connect to D30. You are looking for the Resistor end which is not connect to D30. Hope this helps.

You have a PM. or it may be two.

Ok I found the resister and diode .Now I'm looking for ic-6 ?I see the 858 is ic-7? Also can I just solder a wire with shrink tube to the hot end of r119?

IC6 is a small 3 pin voltage regulator. You need to lift the hot end of R119 and solder a wire to it and solder the other end to Pin 1 of IC6 and remember to remove D30. I would post you a diagram but we are having trouble trying to upload the forum, I have reported this problem to Scott (The Defpom) the guy which runs the forum.

If you have a email address I could send you a diagram, send your email address in a PM.

You have Email now with attachment.

OK, I think that I have the attachments working again, so here goes...

Thanks to all that helped. Clarifier works great.

After doing this clarifier how much swing are you getting now. I did a 449 clarifier couple weeks ago but i got the voltage from a diode, cant remember which one and am getting 7 kc swing on the clarifier now and works fine
