It depends who is defining "stupid and irrational." I have been in discussions where I knew the facts were on my side and was not so politely accused of either being stupid, irrational, or some other idiotic manly (sic) cut. Otoh, I agree stupid ideas need to be addressed, but if it can't be done civilly then others who disagree may be offended and then it's up to who has the funniest, thread shutting line. That's my take. Quote Link to comment Share on other sites More sharing options...
Dave A Posted June 29, 2019 Share Posted June 29, 2019 My vote is yes there is no science or methodology needed to build amps. If you have proper empathy with and can emote with your audio device well you can become an audio synergistic village of man and electronics melded into something that surpasses mere technical abilities and methods. How you feel in relationship to your amp will produce much more as your feelings guide you in ways that empirical methodology never could to superb sound. 1 Quote Link to comment Share on other sites More sharing options...

Dave A Posted June 29, 2019 Share Posted June 29, 2019 Hey Dean there was lots of public discourse but it was face to face and no anonymous keyboard warriors. Outside of this forum I am going back to those days more and more. You see people eating out and the whole family sits there with their dumb smart phones and no conversation. Go to a tractor pull and same thing. 2 Quote Link to comment Share on other sites More sharing options...

Does anyone have definite info about that? Yes, they use NFB, but it's what makes the class D amp drive difficult loads with ease. Quote Link to comment Share on other sites More sharing options...

So before the internet (1991 for sure) that would have been talk radio, organized protests or rallies, daily newspaper where folks would write in and comment on topics or the editorial sections, political talk shows on tv on Sunday morning for example (still occurring like Face the Nation), the Johnny Carson Show, the Late Night show, scheduled local government public meetings. So many examples of public discourse prior to the internet if you stop and think about it. Talk radio was huge before the internet, where folks could call in live and interact with a moderator or discussion panel. Organized public discussions at college universities too, big in the 60s and 70s. Quote Link to comment Share on other sites More sharing options...

Consider the venue and participants. This is a Speaker Forum that has experience allowing conflict in discussions and when it gets too nasty hyperbole flies and nastiness ensues...Instead of "excellence" we get name calling and then the lowest common denominator drives the discussion. Those who have sensible, factual rebuttals gets tired of typing and the "telling it like it is," crowd feel emboldened by getting others to stop participating. Quote Way too many overly sensitive feedback adverse triode trend hoppers making the rules these days. I too have seen this and think we should vote them out of office! Quote Not sure how an internet pillow fight between a couple of electro- geeks is a threat to forum security. Time to grow some hair on your pentodes and toughen up. - TH6AQ5 Funny line but it doesn't take "hair on your pentodes," to realize that internet bullying and name calling is only manly because there isn't any repercussions in the real world for doing so...Btw, I am not offended by factual/civil debate but instead with idiotic rhetoric that's designed to piss off folks rather than inform. 1 Quote Link to comment Share on other sites More sharing options...

What I realized discussing politics in the BS Section last election was how much influence social media had on our population and how it could be manipulated...I didn't realize at the time how MUCH misinformation was being sent out, real time, and our masses didn't realize who was manipulating them and how susceptible they were to it. I wish we had those threads back because it is living proof of what Volume I of the Mueller report exposed and I was trying to convey at the time which was why are we talking about so much extraneous BS when there were issues to discuss that affected all of us--I started a thread Do Words Matter? at the same time they were trying to coin the phrase, "Alternate Facts," and alarmingly the jargon was dismissed, but the practice continues and influence those who don't wish to dig deeper into the issues. Insofar as what went on in this thread before deletions occurred, I didn't see it and only got involved afterward. For the record I have no expertise in designing amps.

karlson3 Posted July 2, 2019 Share Posted July 2, 2019 I'm going to take just a guess - that a number of "high end" tube amplifier products were/are the result of listening rather than following exact rules of the longest AC loadlines and best-positioned operating points per Radiotron manual vs tube characteristics and that perhaps ARC, and Quicksilver have done this practice and certainly Bruce Moore and Scott Frankland. (It would be good to have a scope to hunt down potential oscillation problems - my 8417/417A tube sure oscillated enough to block the signal) I once had a modified Dyna Stereo 70 which had probably been modified per Eisenson's "TU-BE OR NOT TU-BE" and for some reason it would LF "motorboat" on a box speaker - but would play on the resistive Magneplanars. Some designers seem not to be so fixated on things. Grommes designer Al Hart in a note to me seemed glad to see tubes dead and happy with an op amp RIAA stage with global feedback. Stu Hegeman in later years had a similar preamp. (I'm sure the HAPI is about forgotten vs his Citation I & IV tube units) I like to see those who are passionate and experiment (Jeff included) The Japanese "Ultra-Fi" movement several decades ago imo was a very good thing for those who love horn loudspeakers. Jeff could easily throw high H chokes on the chassis, series pass regulators, big caps - - but apparently has found something which works better for his* sense of how music should sound. (* people don't hear/perceive things the same) FWIW I've heard "a little" hum from commercial tube (and solid state) amps in my lifetime. Audio - like other hobbys, politics, religion, can bring out strong opinions. Maybe its best to use that phrase - "lets agree to disagree" . 1 Quote Link to comment Share on other sites More sharing options...

Coming from the amps themselves? or out of the speakers? If the speakers that needs to be tracked down and squashed AFAIC. The amps themselves if objectionable can be removed to a remote location.

a9050lx Posted August 7, 2019 Share Posted August 7, 2019 Lascala is a fine instrument to test audible hum. I think building amps is therapy as much as a search for better sound.still, I run out of room.I just hope some of my equipment is used as intended when I no longer need it. 1 Quote Link to comment Share on other sites More sharing options...
