I see the problem here... Put it in a fancy/unique enclosure, add a toggle switch that says 'tube' that does... something, give it some...

I'll probably publish it in some magazine, since nobody wants to buy it anyway :) There nothing to it, except for the right choice of...

I keep working on and improving an onboard headphone amp I designed. I think it really whips the llama's ass. I use it all the time at...

I swear, there's a thick mane of luscious hair under that cap 😜

There’s a lot of hair in that pic…except one guy….

Me and the Mrs. with some metalheads

On the top circuit: you are missing a resistor to ground at the positive input of the first opamp. Won't work well as is. Bottom...

You haven't heard this from me, but I often just make a big blob of solder that covers all pins on one side of an IC such as the one in...

I'll always tell whoever is listening that SMD isn't nearly as hard as it may seem. You just need a fine-tipped soldering iron, thin...

I always see people commenting around the forum that soldering SMD jfets is hard and frustrating. The truth is that it is really easy...

No idea. Is the vari-cap grounded in the radio? Then maybe, but you'd need an op amp with a wide bandwidth (tens of MHz), so it can...

I did a little bit of digging and stopped when it basically brought up conference papers on active component designs (which don't get me...

^ Depends on the circuit. Panning adds a significant series resistance when not fully at one end or the other. The circuit above acts...

I read somewhere that there's a floating version, but haven't investigated further.

If you've used (or thought about using) something like a rotary switch to switch between different capacitor values in a circuit, you...
