Looking great, as always. Love the polished aluminum look. What modifications did you make to the Spooky Tooth?

Send me some closer pics of the PCB and measurements for the board dimensions and the screw locations. I might have something that's already most of the way there.

Haha, fair enough

Are you sure? The TI data sheet says that the TL072H noise spec is 37nV/sqrt Hz, which is more than twice the 18-20nV/sqrt Hz figure for earlier TL072s. (I don’t mean to sound rude, @Cybercow, but the writing style of what you posted reads like it was written by AI.)

Cutting off the end of the rotary shaft is surprisingly easy. It's extremely easy with a hacksaw, but in my experience you can even do it with the foil cutter on a bottle opener and still get a nice, clean cut.

Nice build! I used Hill House, one of several fonts based on the handwriting of Scottish architect Charles Rennie Mackintosh. You can get a similar look from the ITC Willow font. Which knobs did you use on your Cosmopolitan?

I've used them in almost every single build that I've done for the last two years. They're great.

Yeah, those are almost certainly germanium. Note the whisker in the middle of the diode, which is not found in silicon transistors as far as I am aware (and is certainly not found in modern ones). I'm assuming that you're doing this commercially if you're buying 1000 as a trial.

You really should include a picture with this post, @jdduffield. But as a general matter, if the diodes look like the bottom two examples in this picture, they are silicon if they look like the top one (see the whisker in the middle of the diode that @Cybercow mentioned?) then they’re...

Are you sure? I just checked and Tayda definitely still gives you a shipping quote. Go to your cart and look on the right side of the screen.

Are you connecting the positive and ground rails to the DC jack directly? It looked like that at first glance. If that's the case, try connecting a 100Ω resistor in between the DC jack's negative lead and the negative rail or a 100Ω in between the DC jack's positive lead and the positive...

Awesome build, both inside and outside!

No, the sleeve grounds are negative grounds, and the input jack sleeve is grounded to the enclosure. (I typically only ground the enclosure to the input jack.) I only use VCC as positive ground for the DC portions of the circuit, i.e. transistors and the resistors that are connected to them. I...

This is my first build in a while. I tried a few new things with this build, and I'm rather pleased with how it turned out. As with pretty much all of my builds, I couldn't have done this without some of the people on this forum. I'm a longtime fan of @andy-h-h's blog Vero-P2P blog. It's an...

That’s what I do on all of my builds. It looks clean and it makes it very easy to remove from the enclosure in the event that you need to troubleshoot or modify anything.
