Thanks I did eventually figure that out. I have so many components and spec sheets saved in a folder on my pc that I somehow clicked on the wrong one and read zener. The circuit I got that for was a design from someone that does amp mods and it did work for clipping however I’m still trying...

My master is post tone stack. I just realized these are run in parallel not end to end like a true Jose clipper so I’m going to be ordering some more parts. I may do

And yes I will definitely check them with jumpers.

Thanks for the replies, I will have to go over my work one more time but if I can’t figure it out I should be able to change it to relays pretty easily. Appreciate the help!

I have a Jet City 100HDM that uses an Optocoupler switching circuit to switch channels. The circuit is very similar to the SLO circuit which uses two optocouplers to switch the gain controls and two for the channel volumes. There was a known channel bleed issue which I obtained the parts and...

Just to add the mpsa06 circuit has a parallel resistor the 1n914 doesn’t. Not sure if that matters.

The ones I run from the cathode follower are actually 1n914 and I’ve just discovered they are zener but not sure on the voltage, the ones i tried from the master volume are 1n4747a and are 20v zener diodes so I was mistaken. I’m new to some of this so I need to do more research and read my data...

Thanks for giving me some ideas and options to think about. Still I’m the process of trying some different components, values, and locations. So far I have not tried the 20v zener type yet. I do have a switch to change from silicon diodes to mpsa06. To my ears the silicon diodes kill a lot of...

What are some of your favorite diodes and or tansistors and combinations for clipping circuits and why? How are you combining them and where in the amp circuit are you placing the clipper? Just trying to get a feel for the range of combinations everyone uses and the thought process behind it. I...

Well then I’m in good company since we are of the same camp! Appreciate your knowledge my friend! I am learning a lot on my journey however the two years that have transpired feel more like months since I often get lost in what I’m doing. I have so many questions running through my head all at...

Thanks for the reply! I kind of figured the part about cost and availability but wasn’t sure, I had read in another post that someone used multiple caps in a depth circuit because it made an audible difference.

Hope I’m appropriately posting this question apologize if I’m out of place. I’m about two years into my journey of learning amp modding and my question is what would be the advantage if any of running two capacitors in parallel as opposed to one single capacitor in a circuit? Looking at some...

Hey just saw you have a 100hdm, I did a ton of mods on mine and I have to mention if you haven’t seen it there is a channel bleed issue with the Vactrols for the channel switching circuit and can be easily fixed. Not sure if you need it but this was a major problem and made the amp sound...
