This is another fun time with vero board! The metronome from "Electronics Projects for Musicians", of which you can find a PDF on Google, which I highly recommend doing. I built this into a 1590A enclosure for my daughter, to use with her piano. It has a Pretty good "click" that goes from around...

This forum needs some threads, so I thought I'd throw in my hat. All of these are VERIFIED, so have fun! First up, a super handy inverter vero, for that old fuzz! +9vdc to -9vdc! Next up, an FV-1 module with adjustable frequency. This has come in handy ALOT. Replaces the crystal...

According to a schematic I found online, the boost is part of the output buffer, so if you have a unity output, the circuit is probably ok. The switch throw selects between a 10M resistor, and the 500k boost pot. It connects to the inverting input through an 11k resistor and a 4u7 electro cap. I...

Try a bypass cap parallel to R7. Start with 22uF, then you can adjust from there.

Not sure about the program you are using, but on diptrace this would be in your copper pour settings, something like "Copper to Via keepout".

Pull the chip, and voltage probe the socket to rule out the IC. My 22/7ths is very loud.

A B1k pot with a 180 ohm resistor from pin 2 to ground will give you approximately a 152 ohm pot with a "C" taper. Wire this in series with the fuzz pot..

Dangit! Of course they did. I just made my order a few days ago..😖

Made an order last week at JLCPCB for some personal stuff, a few odds and ends. I live in midwest America, so shipping through DHL was like 30 bucks, my order was 43$. I was charged 100$ extra just for Tariffs! 145%. total was 170$ something. Fun Times!! Sorry, just had to complain a bit..

Sorry - There's... a lot to unpack from what you've asked. How about explaining a bit more of the situation.. What's wrong with those poor little mosfets?

Kapton/polyimide tape! Made to do what most use blue tac for.. Everyone should have a roll! https://www.amazon.com/s?k=kapton+tape&crid=ZH9GBL61C4D4&sprefix=kapton+tape%2Caps%2C171&ref=nb_sb_ss_p13n-pd-dpltr-ranker_1_11

Probably just a manufacturers mark. Does it rub off easily? Capacitor goo, (IME) is usually a nasty, brownish color and leaks from the bottom. The cap will also usually be misshapen, though this can be subtle.

Yeah, I gotta say I tried 180k as well, and it's fine at 180k. Less volume, but not a problem amount.

Can you stack OG Dan Armstrong's?🤟 Toggle get in the way? Never handled an OG..

Oh Yeah, This.👆It'll get you through the gig, but the scratch will soon be back.

Looks like the "power in" on the octave footswitch is reversed from the others.. Edit: Yeah, not the power. Just your footswitch wires. Don't troubleshoot while drowsy!

From Music6000: From the Builder, Thanks Carl - FC : Let's start by sorting the JFETS. As we saw on the datasheet, J201's can have an Idss value from 200uA to 2mA. That is a huge range. For Q1, you want a J201 that has an Idss from 600-800 uA. For Q2, you want one with Idss about 400-600uA. So...

Are you taking resistance measurements with the power on? The power should be off for resistance. It may not change your current readings, but it sure will give erroneous readings sometimes. The meter sends a known voltage through the leads, then measures the current, which gives resistance-...

When I've had mosfets go bad, they usually read as 2 diodes, or it reads as unknown part on a TC-1. Your Source voltage seems high..
