  1. Thank you, I’m kind of also coming to the conclusion I need to learn Illistrator or Inkscape for vector creation. Like guitar, wish I would have picked some of these things up years ago.

  2. RIP, Alto Reed, sax player for the Silver Bullet Band. Boy, if you don't feel the chills when he kicks in here... well, it sure gets me every time.

  3. Looking good, I'm dying over here waiting for mine to show up. Any day now, any day. What CAD/CAM are you using? I've been peeking at Chinese CO2 lasers on Ebay that work with Lightburn, way easier on the pocket book than comparable Epilog/Trotec machines.

  5. To see what and how to improve, let's have a look at the original schematic. KSA-5 is designed along the lines of "moderate feedback", that is, it uses very little to no global feedback but lots of local feedback a.k.a degeneration. The pair of input JFET buffers (Q1, red box on the schematic above) run independently of each other and outside of the global feedback loop. With low loop gain, they see very different signal levels, so the differential stage downstream doesn't cancel their distortion. (BTW, because of this JFETs need not be matched. Also, the expensive and hard-to-

  6. ^^ I almost bought a pair of those some months ago....

  7. Oh, I see, thanks, Steve. I'll wait when it's completed so I can watch at my own pace. Not having to wait for weekly episodes is the best thing these streaming services invented.

  9. I have not, though I probably will now. Feed and speeds are still a bit arcane to me. Easy enough for wood now. But I know the Shapeoko can do softer metals and I intend to do that soon. Even picked up a surplus fridge compressor to kit out as an air assist/mist cooler

  10. I get that. There are 1001 projects in my mind, how many actually will come out...no idea. Have you checked out the cnccookbook? Going to give it a whirl to see if it helps out or is worth while, 30 day free trial.

  11. If either of you ever need something drawn up in CAD and converted to a DXF or even (maybe, haven't tested completely) an SVG I can make pretty quick work of it. I'm shite at 3D stuff, but flat vectors should be no issue.

  12. I’ve reduced power board voltages to +/-12 V. Two Mean Wells 12 V capable to deliver 29 A. Heat sink temperature decreased considerable – of course. My old ears think the sound is as good as with +/-24 V Next step is to make a few more boards to get a balanced set up.

  13. A great Tiny Desk concert (home) by the Iranian-born Sevdaliza. Not much to argue about her 2020 release being one of the best regarded pop albums of the year.

  14. Cutting has definitely been an uphill battle with a diode laser in my experience. I have not been paying attention to what rig you are running so I may be in a totally different court. Also Lightburn was worth every penny for laser work. $40 is nothing compared to some of the other CAD/CAM programs out there. Those cutouts look heckin dope! ....if you wouldn't mind sharing the vectors..... I've been doing Arrow of Light plaques for the local cub scout troop. I won't share the finished project because I feel weird sending out names of children but the arrow was cut out with the router

  15. I built my KSA-5 clone back in 2013 (see my post dated August 9, 2013 in this thread on page 8) but was never quite satisfied with it. I made every effort to make it look good and perform well, and it was well within the original KSA-5's specs. Yet, although it worked well with my 32ohm Grado headphones, it could not compete, in my subjective opinion, with Musical Fidelity's X-CANv8. Connected to a pair of 8ohm speakers, the clone would become rather confused with anything but simplest music. Because of this, the amplifier fell into disuse and was gathering dust on my rack. Until this wee

  16. I thought my comment was pretty benign, Gene. This isn't really a headphone forum. Most members have been here more than a decade, date back to the earliest days of Headwize, and are friends in real life, despite the thousands of miles, oceans, continents and everything else in between. Are we occasionally rude? Yes. Were we particularly rude here? No. If you'd read around a bit even just in this forum you'd have seen that the top 10 threads are so are either Stax related or about boutique niche headphones. So no, you posting a review of your new AKG K240s was unlikely to generate any sort of

  18. A guy on /r/audiophile had a pair of 18" subs for a live PA that he was unable to sell, so he added them to his home theatre. WAF is quite low as it turns out.

  19. Based on my experience, that threshold can be built with only a measly $17k in tool investments. Make sure you buy every accessory as well and the full Woodpecker catalog so everything comes out straight. Easy. 😁
