    SOLVED Who else gets gremlins when socketing transistors?

    I like sockets in case I fuck up the pinout of an old transistor I paid $8+ for. It's a protection of investment thing. It also feels nice that they are more easily reusable, I guess. I should probably get over that.

    Help me finish a pedalboard

    My latest project has been an aesthetic homemade classic rock board using 1590B enclosures with top jacks, bare aluminum enclosures, and identical knobs. Currently, the lineup is: 1. Fuzz Face (PNP Ge) 2. Green Ringer (set up to be dark and very loud - BC108C and 2N5087 transistor complement...

    SOLVED Who else gets gremlins when socketing transistors?

    Marking this as the solution because I just tried it and it's perfect!

    SOLVED Who else gets gremlins when socketing transistors?

    Tonight, I built a Fuzz Face with some Germanium transistors. It sounded amazing on the breadboard, so I committed it to vero using a layout I know to be good. Suddenly, it won't bias right and it sounds weak and shitty. I ended up rebuilding it on a breadboard, getting a good result, then...

    Gutting a crappy wah and putting a better circuit in

    I do plan on using the stock Fasel inductor, assuming I can get it off the board and get it onto another

    Gutting a crappy wah and putting a better circuit in

    I've had a Crybaby Classic since my 16th birthday, and I hate the fucking thing. The sweep is wrong, it has no LED, the switch is hard to actuate, it has a huge gain boost that wrecks my fuzz pedal's shit, and it is a tone-suck even when off. Great shell, though! I figure I can make use of the...

    SOLVED How to reverse "flipped" PNP circuit back to positive ground?

    That helps, thank you. The FF is this general topology: Using this layout:

    SOLVED How to reverse "flipped" PNP circuit back to positive ground?

    @gonzo I'm not sure I'm up to a P2P build quite yet. I really like sockets. Feels like a safety net, when Ge transistors are $8 each. That matches what I have wired up, minus the diode. I can take your schematic, and put the power at the "top" so to speak, so things are oriented "the right...

    SOLVED How to reverse "flipped" PNP circuit back to positive ground?

    I'm sure it's a very simple problem that I don't yet have the tools to explain, and if I did, I would not have the problem! I agree that the schematic is funny looking. I omitted the diode because it's obviously wrong, and I hate the way he draws PNP transistors and power rails. I'm glad it...

    SOLVED How to reverse "flipped" PNP circuit back to positive ground?

    Not one specific to the layout but it's the basic PNP fuzz face with custom resistor values to make it bias correctly. I'm sure it is the same as the Dallas arbiter schematic in most ways I'm abandoning the thread though, I'm going to figure it out when I can, I'm going to repost my question in...

    SOLVED How to reverse "flipped" PNP circuit back to positive ground?

    It isn't battery powered. I posted the schematic last night, scroll up for that

    SOLVED How to reverse "flipped" PNP circuit back to positive ground?

    @giovanni The RM layout is labeled correctly, as far as which rail is (+) and which is (-). The board powers and passes signal just fine on its own. When in the box sharing a power connector with the FF, suddenly no signal passes through either, though there is still voltage at the transistors...

    SOLVED How to reverse "flipped" PNP circuit back to positive ground?

    When I read that, it feels like I'm not taking something into account.... bear with me. Forgetting the diode (I put them on the power connector), I reverse the order of the caps and transistor, and the power leads. Aren't the resistors now connected to the wrong legs of the transistor? Do I...

    SOLVED How to reverse "flipped" PNP circuit back to positive ground?

    This also isn't what I am looking for, it is the opposite. I don't want to change the fuzz face; it doesn't work correctly that way. Oscillation happens. I want to change the specific Rangemaster vero layout I posted so it is a proper, positive ground, PNP using circuit that has no charge pump...

    SOLVED How to reverse "flipped" PNP circuit back to positive ground?

    Here's the schematic from the website. See what I mean by "I want to flip it the right way"? That's easy enough to do in a drawing, but when I look at the veroboard I can't see what the difference would be. Positive goes to positive, negative goes to negative. And yet, something is still...

    SOLVED How to reverse "flipped" PNP circuit back to positive ground?

    I deleted the photo of the box because it isn't useful to get the answer I'm looking for. I didn't use diodes on the board, but rather a single one on the power connector itself. Gives me a lot more room to solder stuff! I've already torn it apart and separated the circuits. The RM works great...

    SOLVED How to reverse "flipped" PNP circuit back to positive ground?

    EDIT: THE SOLUTION IS TO UNDERSTAND THE DIFFERENCE BETWEEN POWER AND GROUND VS. POSITIVE AND NEGATIVE POLARITY. IF YOU THINK IN POLARITY, YOU'RE FUCKED AND YOUR PEDAL WON'T WORK. The way to edit the veroboard layout below is to flip the electrolytic capacitors around. Remove the diode, because...

    What's on the workbench?

    I was at the lab late tonight, but I made myself work on the Germaniac because I want to jam with it on Thursday at the open mic. How do you like my solderless B-C noise filter capacitor solution? Once things are more assembled I'll find the most aesthetic way to lay down the transistor. Thanks...
