    First build component sourcing

    I'm willing to bet a BAT46 in series with a 1N4148 will have almost exactly the same curve as the 2D304B / KD203A.

    Legit LM308n ?

    Always taking one for the team.

    Getting Started with PCBA at JLCPCB

    So the electro caps didn't bump you over to standard?

    Yeah, the extended parts costs adds up real quick, I was hoping for myself to get the resistors and caps assembled and then finish off the rest myself, but with C0G not being included as a basic that kind of ruins the idea for my single board ambitions.

    Legit LM308n ?

    I'd love to do a metal can Rat build, if only for the cool factor. My ears definitely won't notice lol.

    Getting Started with PCBA at JLCPCB

    In Diptrace, I've created custom components, they have the JLC catalogue number as an additional field so at the end I can generate a BOM. I essentially went through all the basics, or preferred extended if necessary, for resistors and caps and created a component for all of them. KiCAD has a...

    Getting Started with PCBA at JLCPCB

    Nice. Given I just build for myself I usually only need one copy of a board. So with the lack of C0G caps available I think SMD might actually not be worth it and TH will end up cheaper. You can also make boards fit multiple purposes, but then they probably won't share many components so the...

    When it comes to Through Hole parts, does it matter which ones you choose? Is it just a case of the very first one has the setup fee then you can choose any through hole parts you want from the LCSC catalogue?

    9V protections for projects with a voltage doubler (muzzle, klon...)

    Max voltage for the LT1054 is 15v. I guess what I was trying/hoping to achieve is low drop reverse voltage protection with the first half of @PedalBuilder circuit. And the type of over voltage protection from your circuit where the voltage is limited to a safe max and the circuit doesn't shut...

    9V protections for projects with a voltage doubler (muzzle, klon...)

    Is it possible to have the best of both world here? IE something that looks like this? D7 Could be ~13v for instance to protect an LT1054 or similar.

    Box of 100 1T313V Ge Transistors Tested

    Not yet unfortunately. I'm moving house soon, but I'm keen to try some in some fuzz and maybe cascading overdrive designs.

    True peak limiting PCBs?

    I would recommend Douglas Self's small signal audio. It has a chapter on gain control. Of interest to you might be this circuit. The voltgages and values could be tweaked for your signal level.

    Marshall pedals: JCM800 vs 1959

    I have nothing against simple circuits per se. The electra is an absolute banger. There's a difference to me when a boutique seller with a lot of overheads is selling a YATS, vs a big corporation with scale production in China doing it. That's my point.

    Power Supply Questions - Reverse Voltage Over Voltage

    How would you implement over voltage?

    Power Supply Questions - Reverse Voltage Over Voltage

    I'm open to a DC-DC converter, I guess my question is though, in audio situations, how much better is a regulated vs un-regulated one? The regulated versions seem to add about $10 to the price.
