I just bought a few of these to put together with my son. I wanted to use a couple A's inserts on a mixing console. Is there anything specific that I would need to change to run it at 18v? Thank you.

How Do I? Beginner's Paradise. / Holy Roller
August 16, 2018, 01:08:05 AM
I'm a newb, nuff said right?
I loath asking questions, but here I am. I've searched high and low for a good, not so terribly difficult schematic for a DIY compressor. The Holy Roller seems to be just the right one for me. My question is many fold my friends so sit back and enjoy the newb nonsense, and hit me up with some kind of answer. I appreciate it. Anyway, I want to use the Holy roller as a vocal/bass guitar compressor, since it is an "La2a style" limiter/compressor. My questions only arise from wanting to up the voltage to between 18 and 20v for headroom with the vocals. I've already decided to use the 2sk117 Jfet from the Baja man version, and I've read that they're interchangeable. I'm going to assume that that first indicator LED will explode immediately if I don't lower the voltage for it. Now, I'm a country kid so bare with me, but if I'm doing the math right; I would need 895 ohms of resistance between power rail and 5mm Blue LED. Is That right? Is there such a beast? I have some LM317 voltage regulators, so would that be better? Overkill? More chance for noise? Alright, first five questions down, and you're still with me.. Sweet! I'm going to use two LME49860NA ICs that are rated at 22v, so I should be good there. I'm not using the chip for any other reason than it being the highest rated that I have around, so I don't know much about that. I do Know that I'm down to my final question. Is it as easy as doubling the Capacitor, and resistor values? Thanks for hanging with me, and Thanks for any help.

How Do I? Beginner's Paradise. / Mad bean 4:1 compressor pedal schematic?
January 21, 2018, 05:01:28 PM
I wanted to try point to point wiring with this schematic. I've never done it, and I know it's cheaper and simpler to just get the pcb, which I have already done with other projects, but I want to build a point to point for fun. My only question is... what is the little circle with the word "pin" in it, and where does that terminate?
Thank you
