    Old Solder

    285 rosin is still pretty active, and a new spool like that would be $$$.

    Old Solder

    Yeah, I have a spool. Less shiny joints than 63/37 w/ type 44 rosin, but also a slightly lower melting temp. Mine came in an expired lot from a friend who works as a tech in aerospace applications. You can make it look shinier by using desoldering braid on your joints, which I tend to do for SMD...

    Jlcpcb and tariffs

    Some of my OSH orders are under $1 shipped, I usually try to at least double or triple up in that case to hopefully make it a little more worthwhile for them.

    Desolders

    Buy once, cry once. I've had my old Pace unit up for sale here for eons with nary a bite. For me it was most useful for DIP opamps and bigger ICs, but I just don't use through hole parts often enough to ever bother to break it out any more. I prefer desoldering braid to manual suckers, by a...

    A multimeter that can read frequencies over 50hz

    My Fluke 179 is rated to 100kHz. Works great for audio, and I have a dedicated Fluke frequency meter if I need to go higher.

    A Somewhat Functional Buffer-Splitter-Mixer-Switcher-Boost Pedal

    Sure, sure, but can you mod or repair it without pulling it out of a pedal or instrument? :cool: Bur seriously, I've been referring people to you for things I don't have any time or desire to duplicate, better for both of us.

    A Somewhat Functional Buffer-Splitter-Mixer-Switcher-Boost Pedal

    Contrarian that I am, I prefer offboard wiring and tiny modules that I can buy cheap from US vendors. But I still use mostly through-hole caps...go figure! ;) So this is my (soon to be open source) buffer/preamp module: I have a few mixer/blender ones in development too. Offboard wiring...

    A Somewhat Functional Buffer-Splitter-Mixer-Switcher-Boost Pedal

    I use OPA1641/1642 for a ton of builds, they are great. Much more stable than the 2134 in wonky DIY builds too, IME.

    Jlcpcb and tariffs

    I absolutely love the OSH purple and gold look, but yeah, the nubs do suck. For me the other viable US based alternative has been DKRed, who give us a mildly annoying random board ID number instead of the nubs. They also don't do plated slots, which I use occasionally for onboard preamps...

    film capacitors

    EPCOS/TDK for polyester, Kemet PHE426 for polypro. I've been using the latter in 1nf-68nF for many years, not so much in bigger sizes for typical coupling applications though.

    film capacitors

    Thanks for the heads-up, I managed to miss the end of life notice Mouser presumably sent me. I've been getting way too many of those notices over the last few years! I threw in a quick order for 100 of my most used size but that won't last me all that long, and then I may have to revamp quite a...

    film capacitors

    If in the US: Mouser first, then maybe Digikey, Newark, Arrow, certain well vetted eBay vendors, etc. Buying in bulk quantities brings pricing down substantially, and you do need to look at spec sheets carefully to make sure you get the right footprint. The Mouser search engine takes some...

    Favorite 1590XX builds

    I did this one for my Dojo (banjo/dobro hybrid), separate EQ for the piezo and magnetic pickups and then blend to mono: The Dojo has TRS output, so cabling is just one in one out.

    I use DK Red quite a bit, for my typically very small boards the only major drawback is the non support for plated slots, but there’s always OSH for that. I tried going direct to their primary fabricator in California for a quote once, DKR is actually a huge bargain in comparison!

    Passinwind Open Source Hybrid Filter Preamp Builds

    PM me, I have a few trick new parts that might make your build a little easier. If you get it right you may never even think of going back to a shelving control, IMNSHO, but it's very very easy to not get it right! Just another tool in the box, hard to say from here if it's the right tool for...

    Nobelium - tube bass preamp project

    Markertek should be able to special order one for you.

    Tracers, lemme hear you say whattt

    Real Time Analyzer. I highly recommend Room EQ Wizard, which is freeware. There are VST plugs that work OK too. And not a hint of offense taken, I was just trying to flesh out your post! So suppose we wanted to see for ourselves where the actual nominal flat setting on a G-K MB500 Fusion amp...

    Tracers, lemme hear you say whattt

    I do computer RTAs on anything EQ related as a matter or course, and typically scope anything and everything I work on right off the bat as well. ;)

    JFET Testing - ARP 2600 Synthesizer

    The customer repair tech from ARP back then is still around, are at least was in 2020 when I had a nice chat with her at NAMM. I'll see if I can scare up some contact info. Unfortunately I never got to work on any 2600s when I was a QC tech there, but I played the two in the employee studio...

    Tracers, lemme hear you say whattt

    I put it in LTspice and see how I can improve it, of course. I've actually done this all of one time, as there were no build docs for that particular pedal at that time, and it was going to be a build for a friend that I didn't feel like doing my own design for.
