The lastest and greatest used the 150k series and 100k shunt. I did not have a chance to pick up bypass capacitors.

To try the bypass capacitor, you suggested splitting the series resistance in two (75k + 75k) and placing a capacitor in parallel with one of the resistors. What would you suggest for the value of the cap?

I'll stop by Radio Shack tonight on the way home and give it (another!) try.

You might get an assortment of resistor values up to 150k and an assortment of capacitor values in the pF range. You can bypass the 150k series resistor with a capacitor and the size will determine where treble boost starts. But that won't set the amount of boost, only where it starts. You can reduce the amount by splitting the series resistance into two parts, and bypasing them separately. One resistor might have no bypass or it might have a different value than the other. This just gives you some flexibility, that's all.


Many thanks! (nt) [message #1812 is a reply to message #1795] Thu, 26 May 2005 10:11 Go to previous message
