Title: Whoops...messed up my line out voltage divider
Post by: joecool85 on February 17, 2014, 01:41:29 PM
Years ago I added a line out to my k-20x by using the 10k/1k voltage divider the k-20 used. Except evidently I wasn't paying full attention when I did it. I put the 10k inline from the positive speaker lead to tip on line out, then a 1k from the negative lead to line out sleeve. I should have put the 1k from tip to ground to complete the voltage divider. Luckily I only ever drove a lm 3886 with it. I'm going to fix this soon as I'll be in there anyway doing an IEC jack mod.

Why not just replace the 1k Resistor with a 5 or 10k pot? :tu:

I wanted it to match the old k20. I fixed this last night actually.
