Ive done 4 and 8 eeprom already, will work if space permits and your switch wiring is correct.

PM me for contact info.

The pads are meant specifically for that, as I mentioned I placed the switch to verify the pcb was working correctly before drilling hole into enclosure, just in case. 👌🏼PM me for contact info, I will sell you one.

Thanks to all who worked this out together here and shared enough info for me to put this together. It actually sat here unverified for a long while, I needed a second eeprom lol. Finally got around to verifying it and all is perfect. The internal switch was simply to verify before drilling a...

So I’ve been looking at this and it seems based on the schematic drawn that the pins I marked in green should be connected together/toground as well but are not in the layout drawing? Is this actually verified at this point? I want to give it a shot.

So the new relay boards are out now?

Is it safe to use LT1054 with pin 1 simply lifted? With it connected I had overheating issues, with it lifted all has been well for weeks. Nagging me though as I am not sure this is OK to do. Would rather lift pin than cut trace.

Ha, So I thought those would be bias trimpots when I made my order and ordered 5K in anticipation of testing with higher voltages. Realized after the fact when I went to check bias. My build sounds amazing with them maxed however, I wonder how much more gain I am getting than stock?!

I wasn’t concerned with the resistor values as they are already confirmed and well visible in the other picture set. I didn’t even look at them in this set to notice the glare. I thought the solder pads, switch and jacks were what he was asking to see more clearly. Inspecting the resistors I...

A Simple passthrough didn’t work well for me either no matter what I tried. I now use a buffered splitter to send signal to the key input and main signal chain AND a small isolation transformer between buffer out and key input to prevent a ground loop induced in my rig. Perfect for my needs now.

That looks great! ??

I took some more pictures and tried to get everything sharp enough to see. Not sure if they are better. ??‍♂️ Let me know what you think.

What you are asking for was included. Jacks/full size etc. I just reviewed all the pictures, and those pics were as large as the forum would allow me to upload. I will take some more when I get home and post them again to see if I can get anything larger/clearer. ??

Pictures were posted above. I can take and post more. I didn’t stop following up? ??‍♂️ Others clogged up the thread asking about my resistors because I posted pics.

Still just lying here dead. Anyone have any other ideas. Im not sure what else to do but blindly poke at circuit with probe. ??‍♂️

no, not at all, I just didnt look at it for a few days while distracted by some other things and then picked it back up to get that last “measurement” yesterday. You last asked: “...Measure resistance from Q2-E to IC1-7 with power off. Since IC1 is in a socket, make the measurement with IC1...

Some are up to $1 even lol most are $.60 average id say. Depends on source. The .1% are like $2 a piece lol

Q2-E to IC1-7 seems to do the same thing as C2, climbs to 200K then flashes to 1. Why do I need to swap the multimeter leads to get consecutive readings?

That is up to you to decide. ?

? I realized that after posting and edited my comment. 1000uf lol. Great, awesome technical explanation, always excited to better understand these effects. will have a look at that as well. Thanks again. ?
