Jensen has or at least had schematics for a few nice passive ones on their website, definitely comparable to the JDI. I may have copies if you can't readily find them. I also made a very good sounding active one using a Creation Audio Labs Redeemer buffer coupled with a Jensen line level...

I have a Goldtone Dojo (banjo dobro hybrid) wired like that, it works great. One caveat is that you want to keep the output cable as short as is reasonably possible if using an unbuffered piezo element. I've done a variety of breakout boxes and blend/EQ boxes and settled on this one for the...

For SOIC-8 to DIP-8 I just buy half a dozen through OSHpark every year or two, at $0.95 for three, shipped. As you say, doing your own layout is dead simple, and there are probably design shares at OSH if you look hard enough. But I'd just buy bigger ones from Robert if I were already ordering...

Yeah, PPCB first of course, but I have various open source utilty board designs ready to go for stuff like that. I don’t have them up on Github and Oshpark yet but it wouldn’t take to make that happen. All of them use SMD opamps and resistors though, if that’s a deal breaker. Notthing super...

I'll probably be in for a few of the discounted ones, but I still haven't even broken out the one with the edge connector you sent me since I have been plenty busy with the original version. Yet another heat wave may keep me out of my shop for the rest of the week, but getting set up for stereo...

I'll be sitting down with my luthier friend in the next few weeks to explore if it would be worth my while. Last time I went was 2020, which would've worked out great if not for The Plague. I had stuff in like 5 different booths, good times.

I use Nomex sheet or fish paper for my modular PCBs with offboard pots and switches. Generally I do origami boxes and then use velco, dual lock, or double stick gel or foam to secure the box to the enclosure. The way I do it often allows doing mods without even removing the board or pots from...

Which ones? I built up a Crystal Lettuce Black Edition with a few mods to tame the gain a bit, which I really like. I had fun with the graphics too:

I really like the results of the dual limiter approach in the SB amps, FWIW. You might also take a look at Andy Field's patents on the Genz-Benz and Mesa limiter schemes, which strive for something like tube emulation a bit. And then there's a very useful old designer's guide for the old...

@fmcc : you might take a look at the online Traynor service manuals for the SB series amps, which use ASX2 power modules and a pretty simple optical limiting format. I've been using an SB200 head for my friend's weekly bluegrass/Americana jam for the last couple of years, it's actually the only...

Cool, and you're welcome. I had a bit of help from some great people along the way, including the US ICEpower rep at one point. I'm planning on doing a powered cab for acoustic guitar next, which should be a lot simpler and cheaper than the high powered bass stuff. I'm not always too fussed...

Go big, build a Brownout 1000:

Lookin' good. I was deeply involved with the early fEARful crossover design work and still talk to Dave Green fairly regularly. FWIW, I've built DIY amps with both the 700ASC (now 700AS1) and 500ASP modules, The 700AS1 already has a decent regulated +/-15V aux supply, which really simplified...

Fluke 179, somehow I managed to get one on eBay for $125 brand new many years ago by combining a couple of different promotional deals.

A razor saw is a good tool for stuff like that. Yeah, one of these days I'll actually buy one...that's the ticket! ;)

Cool, thanks. The Tayda header pins have always worked fine for me in the Mill Max and similar machined contact DIP sockets, FWIW.

Just curious: why are you mounting SO-23 parts on an SO-8 to DIP-8 adapter? Is that a common hack I'm not aware of, or...?

To be honest, I haven't looked at that aspect very hard yet. I went in with quite a bit of experience with Inkscape, a few trial stints with Illustrator, and lots of experience with other Adobe products like Photoshop and Premiere. Within a few hours I was able to get very good results with...

A heck of a lot easier than Inkscape! I use both though, Inkscape has some very useful features for tweaking fonts, for example. I also like the way it handles measurements a lot more.

Roger that, and something to think about if I ever do any more PCB layouts for DIYers. I‘ve had to kit up components for a number of friends in Europe, I also get how different the parts availability is over there. Edit: Mouser does stock Kemet caps in that footprint too, at right at double the...
