I have a transistor tester, but not a transistor untester. How much does one of those run you? Sometimes having everything tested is dull— where’s the excitement of mystery in my life? It all went away when I tested my transistors.
I've noticed that even SMD JFET's are being marked as Obsolete

That’s the _Q package. Without the suffix, it’s still a factory special order (with many being delivered in the coming months).
Same with the MMBFJ201 Q, But no stock available in singular either!

Again, the _Q package. There are no lifecycle markers for the regular package and over 200,000 units are scheduled for delivery in October/November.

I was just guessing, I didn't even look at the schematic...

I got one of those iRig interfaces...I have a Duet somewhere but it's the first iteration and had some firmware issues. Anyhoo....
It comes with the Amplitube software which is great if you want ala-carte modeling. I'm not sure if there are free previews (there should be) but I'll check or someone please chime in.
Mainly, I wanted to feed some online backing tracks to my new headphones (thank you all for your input btw) and also have onboard effects handy, so I'm using an app called ToneBridge. Punch in a song you want your guitar to "mimic", turn on the backing track...and wander the house and yard in your headphones and underwear jamming to your heart's content. Not all setups are great, and it's not "live" whatever that means anymore...but it's fun as hell.
Obligatory edit: Mostly I use backing tracks from yewtube...if anyone has groovy alternatives..I'm all wrinkles....and ears
Got noodle?

I chose the DT-880-Pro. They are comfortable enough and sound great!
I may also get a pair of open / semi-open at some point.

I use iRealPro which has jazz backing tracks but also many other genres (although I think you need to pay separately for those). It works really well for my needs, but beware: it’s midi sounds. The nice thing is that you can change tempo and key very easily. If I need headphone practice, I can plug my Fender Mustang micro which has BT so I can get the track and the guitar through it. Pretty seamless setup.

Since my mower decided to die, I built a little battery charger since I had a free battery....sort of.
I've got it turned way down as those leads aren't going to take a lot of current, but it works. That little board under the DMM is a charge regulator I picked up at Tayda (though these are sold nearly everywhere)..thus the charger-on-the-breadboard. Unfortunately, the goop used to attach the heatsink was leftover PlayDoh from 1966, and the heatsink was loose in the package....also, it doesn't work so the heatsink isn't really an issue. I ran an audio probe through it, and it hissed at me
. The only thing worth a hoot on that board is the relay, which is likely what is FUBAR.

How can one learn such a power? The power of making a charger that is.Since my mower decided to die, I built a little battery charger since I had a free battery....sort of.

Well, for lead acid or gel, it's pretty straight-forward. Now, this is assuming you have a 15-18v power supply with enough current on tap. Call me lazy, but I didn’t build that bit.

For lithium-ion and the ilk, it's a bit more complicated and I haven't done any reading in that direction beyond the realization that it would require more study time than I wanted to invest
That said, solar charging and micro-efficiencies are of an extreme interest to me and I hope to have time to explore the tiniest of economies because that's where I'll discover the niche.

Battery Charger Circuits
Here you will find a collection of Battery Charger Circuits. It uses a small constant current to charge the battery during the complete charging process.
