  1. Neither is the correct answer. A Hammer A3 (or similar) is the right answer - it is physically smaller than the Powermatic jointer, yet still will give you a wider jointer, and will allow you to get rid of the planer which will free up space for a bigger CNC.

  2. Both is the correct answer. The CNC will be limited in size but there is still a ton you can do and more importantly learn. When you finally get around to moving somewhere you can have a proper shop you will already know what you are doing on a larger machine.

  3. Voja, I think you are seriously missing the point. The big problem with the transformer box is potential SAFETY issues. When spritzer talks about the construction not being up to code, what he is talking about is construction standards that are designed to protect the user from being SHOCKED, or worse, ELECTROCUTED. For example, he mentions that the XLR connectors are not spec'd for the voltages they are intended to carry, which is not aa good thing. The metal panels on the box are not all connected to ground which means that if a wire inside the box should somehow break and touch an ungrounded panel, and you then touch that panel, you would get a shock. That is why all modern appliances (including amps) with metal boxes have their outsides electrically connected to the ground wire on your three wire power cord, for your protection. You admit that you are not a technical person, so you should pay attention to someone like spritzer, who is. It doesn't matter a bit if the headphones sound absolutely perfect, if they could injure or kill you. End of discussion.

  4. The point is that things can potentially SOUND good, but if corners are cut there may be issues with usage and/or longer-term reliability. Some prime examples of this have been HiFiMan (QC issues with many of their phones but often sounded good; and "production" models VERY quickly upgraded to v2 or higher, which tends to mean the product wasn't even a fully finished product to start on first introduction), Cavalli (similar QC type issues and possible design shortcuts), and as an extreme example, Single Power (parts used that aren't in spec for voltages present, poor construction that could literally cause fires and failure; but boy they sounded great). This is not your normal forum, and while it's good to learn about new things there are colleagues in here that can tell many aspects of design and construction quality based solely on the pictures of the innards. So while your opinions on sound are worthwhile in some aspect, it is tempered by build quality questions; so many decide not to move forward and blindly accept sound impressions without more technical info. It could save $ and aggravation in the long run. The argument is that both go together, sound and design/build. So if one is clearly not up to par, then the other doesn't matter - at least to people here. I'm in no way saying these products are like Single Power, but a LOT of people got burned by him/that company.

  5. ...and now a stereo version. Bias 75mA, 125 degrees F at heat sinks and AMB sigma PSU is working hard. Might need better chassis.

  6. It's amazing that certain bands from "back then" still have the fanbase among new and younger fans. One of my ex-neighbors has a son that - when he was all of I think 12 or 13 - had a Misfits t-shirt he would proudly wear. I found out his mom - a quiet schoolteacher - was actually quite the punk fan in the day and LOVED the Misfits. My son has also reported to me that two of my favorite bands - Joy Division and The Chameleons - are held in quite high regards by several of his friends too. So I get to be "cool dad" for a bit 😊 And my old HS friend who died of COVID-related complications was in 2 bands up until he passed; one of them was a Misfits/Danzig cover band....

  7. Me before coughing up to bankroll the continued misadventures of the Commonwealth of Taxachusetts: Ulrich Schnuass - A Strangely Isolated Place (2003). The stunning followup to the brilliant Far Away Trains Passing By. Ulrich managed to outdo himself and that was no mean feat. Probably the greatest IDM/downtempo/call it what you will album of the Aughts. I remember when this album came out and I played tracks off it, I'd have (otherwise incredibly narrow minded) drum n bass heads come up to me and ask me "what IS this music?" Me AFTER the fine state of Taxachusetts is done with me: The Misfits - Walk Among Us (1982). As close to a perfect punk rock record as they ever did. Marred only by an inferior live version of "Mommy, Can I Go Out And Kill Tonight?" vs the much better studio version (which is on Earth A.D.) Walk Among Us is peak Misfits. It's the best distillation of Glenn's savant-like ability to take trash 50s and 60s horror and sci-fi and make it iconic. His unique Demon Elvis bellow is cleaner and more emotive than on Earth A.D. The production on this album is actually remarkably solid, especially for an early 80s punk album recorded on a shoestring. There's some clever automatic double tracking on songs like "Devil's Whorehouse" that lend Glenn's vocals this amazing lo-fi psychedelic feel. The Misfits - Earth A.D. (1982). While inferior to Walk Among Us in nearly every way (except for the previously mentioned "Mommy") this is still a brilliant release. It's both faster and darker than its predecessor. There is less of a catchy horror punk sound and more of a metal influence throughout it. I first got Earth A.D. on cassette at the tender age of 12, during the Reagan years. That re-issue and most later pressings include "Die, Die My Darling" and "We Bite." The former is one of the best songs by the Misfits, so to me the album is incompletew without it. I didn't get a copy of Walk Among Us until '89 when the vinyl got re-issued. I quickly realized that it was the superior album. That said Earth A.D. has always held a special place in my heart because it was my introduction to the Misfits.

  8. When I was repairing Todd's CFA3, I think I did this, and no, the protector didn't trigger. Also I don't recall much noise in the phones from it either. Probably not the best thing to do, and it has been a while since I worked on this.

  12. i have bigtime problems with their cables. for cables with a cable shield the shield has to be at ground potential, not 580vdc. with 2 wires on each stator, the cable is double the capacitance that it needs to be. really messes with the frequency response and high frequency load presented to the amplifier. 6aq5 output tubes paralleled, so maybe 5 watts into 8 ohm speaker tap. e180cc as input tube. medium gain. circuit highly similar to early dynaco, pentodes driven as tetrodes with ultra linear transformer taps. unregulated power supply is a bad joke.

  13. While I'm at it, here is the cable they use: Just took some quick picks with the phone, can't be arsed to spend any more time on this: So those are the cheapest XLR's money can buy and possibly the oddest cable I've ever opened. The signal is carried on those thin wires but the bias is on a massive copper mesh for some reason. Now somebody spent a lot of time making this but that doesn't mean any of it is a good idea. First off, the teflon is clearly very thin when the proper 600V stuff is not and in what world is it a good idea to have the highest current capacity for the bias wires? The bias supply is tied directly to the mains, if the bias resistors fail and all hell breaks loose... you don't want what is essentially a mains cable coming up to your head.

  14. I tried to read that article... holy crap do you honestly believe those cables and idiotic footers make a difference? For fucks sake... Also first good point is build quality... sure. Thanks for the internal pics though as this thing sure is a hot mess. So you have a tube amp... and you could use that to directly drive the stators but nope, they went the worst of all worlds. They take a push pull amp, step that down to speaker level and then step it back up for the electrostatics. WHY!!!?? In what universe is that a good design choice, double up the transformers and cram it all in a small chassis... right next to the power transformer and the inductor. You would be much better off with a cheap tube amp off ebay (the China specials) and a SRD-7. That way there is at least some isolation. Same bias supply as the transformer box, despite this being a tube amp and thus safe, high voltage AC being present which is easy to step up. Hell, a dedicated tap off the transformer would suffice. I just love that one nut in the back right hand corner just not fully fixed. Shows the amount of care. All the same earthing issues as the other amps as it uses the 3D printed corner pieces which don't conduct.

  16. Which ever one you get make sure that you are not tied into their software. One that has a post processor available for VCarve/Fusion/Solidworks.

  17. I am thinking the best way to go now might be an even smaller Shark SD120 CNC and the big jointer. Little CNC will be about 60% the cost and seems to be decent for the template making and basic CNCing I need to do.

  18. I would go with the jointer while you are still learning woodworking skills and add something bigger than a magic air hockey table when you have more room.

  19. She has quite the varied discography, and unsurprisingly, I love it all. The iTunes Essential playlist for her gets a lot of plays. The transition she made from mysterious black metal performer to folk is pretty amazing.

  21. I've been neck deep in tax hell this week, so I've regressed to the mid 1990s: White Zombie - La Sexorcisto: Devil Music Volume One (1992) White Zombie - Astro Creep 2000. (1995) Rob Zombie: Hellbilly Deluxe (1998) I've noticed that it's become very popular among current metalheads to hate on groove metal. For the life of me, I don't understand why. I'm not huge on the genre, but I do love me some vintage WZ and Pantera. Dimebag Darrell was a better guitarist than ...well, nearly anybody but certainly anyone who played in Zombie. His riffs were on another planet in their ferocity. The key difference between the bands is that Rob Zombie is a decent frontman and Phil Anselmo is a cancerous growth. This translates to me listening to a lot more Zombie than Pantera in my senior years.

  23. Here is picture of the amplifier in work. Mono version. AMB sigma 22 PSU. It has four trimmers. Lower middle controls the offset. Middle upper controls the balance. The two outer controls respectively channels bias. Input stage current source/sink approximately 1.7 mA. Output bias 35 mA. Setup procedure I used: • Let heats sink get warmed up to working temperature • Trim offset to zero • Trim balance to zero • Set desired bias of both channels to desired bias Redo previous procedures if needed. I find the setup easily done.

  24. Interesting ideas, wish list, for future Dynahi, Bespav. Here is a new amp board. Initial tests have been successful. The bias control seems to work. Heat sink is Modushop 80mm x 200mm.

  25. Kevin, The pinout of the bipolars is not compatible with the 2sj109/2sk389. I did boards for those and can supply the gerbers. They should also be in one of the dynalo, etc. group buys that Steve ran (sbeylo) some time ago.
