-Replace the limiting Diodes with 3mm LED's (D3 and D4)
-Remove C25 and C35, do not add jumpers
-Replace R14 with a 46k resistor
-Replace R41 with a 680r resistor
**the kit came with 1% metal film 1/4w resistors, not sure if that makes a difference or not.
-Replace C17 with a 1uf Panasonic Multilayer Film Cap (105)
-Replace C36 with a .068uF Panasonic Multilayer Film Cap (683)
-Replace C42 with a .1uF Panasonic Multilayer Film Cap (104)
**the rest of the caps are basic ceramic non polarized caps
-C10 and C18 with 101's
-C26 and C32 with 221's
-C22 and C28 with 121's
And that is the entire mod. 9 caps and 2 resistors.
More recently he included his "noise reduction mod" which I assume helps with the removal of the limiting diodes.
- 2 1n60p diodes facing opposite directions twisted to each other and then bridged between 2 lifted leads from the negative leg of C27 and the leg of R33 that is closest to IC4.

I could also add a trim pot in series to C24 to control the intensity of the gyrator. Or I could replace the gyrator by just a condenser and a resistor in series to ground to rise treble evenly.
When it's written "remove the caps'', do i have to let a "jump" or do i have to wire ? A kind of replacing a capacitor by a wire ?
Thanks for help
