    Now specializing in extreme near-field desk top systems using flea power SEPs and SETs. This mode of listening must be experienced as it can be totally enveloping.

  1. Educational. There are many “experts” claiming that one type of mask is vastly superior to another. This study found little difference between two popular types. Maynard
  2. Since this is about influenza virus, and not COVID, perhaps it won’t be deleted: https://jamanetwork.com/journals/jama/fullarticle/184819 Maynard
  3. Joe, Travis will not be happy that you posted this! I am waiting for his response to my questioning why he believes the patents have anything to do with anti-vaxxers and conspiracy theorists. They do prove quite well that COVID was lab engineered for a very specific purpose. Maynard
  4. Travis, if you get the chance, PM or email me with your reasoning that the patents enumerated in the video have anything to do with anti-vaxx beliefs or conspiracy theories. What social media sites say is quackery means nothing, and YouTube would have deleted the video if it was not valid. Fuellmich, the attorney, appears to be highly respected as well. The patents cited are pure science and were granted to our own government agencies, Fauci, Baric, Moderna, et al. Maynard
  5. [Deleated, so far off topic. Are you vaccinated, worried about side effects] Waiting to get banned……. Maynard
  6. And here is the disclosure Pfizer made to Japan’s ministry of health. Scroll down to the section in English on organ distribution which reveals how we have been told lies about the vaccine remaining in the injection site: https://trialsitenews.com/wp-content/uploads/2021/06/Pfizer-report_Japanese-government.pdf In case, you didn’t see it, look at the thread I started on patents and download the links before they are deleted. You will be shocked what the patents say. Maynard
  7. Jeff, I applaud you for stating your feelings and I am surprised your post was not deleted for presenting a view which is not mainstream. This video explains how mRNA vaccines work and I have read multiple studies which support the mechanism presented and the resulting vascular damage. https://www.bitchute.com/video/uD98ksu0PzQg/ And we know that FDA approval means nothing! Maynard
  8. Voltage regulation in SETs is unnecessary due to the near constant dc current draw under all operating conditions. Of course VR tubes are pretty to look at in a dark room! Deckert is using the option of different voltage drops among some of them to change the plate voltage of the driver which, of course, changes the distortion characteristics to tailor the sound to suit. This could more easily be done other ways but that would not have the “coolness” factor of the VR tubes. Only you can decide if it is worth the extra cost. Maynard
  9. It would be fine to use the 1627 although it may not be much better than the 125ESE in this application. The bandwidth of the latter is extremely wide due to being operated at such a tiny fraction of its output power rating. Personally, I would build the Millie as shown and keep the size and weight down. Look at George Anderson’s measurement of the 125CSE to gain some insight about transformer bandwidth as a function of output power: http://tubelab.com/articles/component-testing/budget-output-transformers/ Maynard
  10. Those who can live with less power can achieve 2A3 performance with a triode strapped 6Y6 which can usually be found NOS for around $4.00. The curves are very similar. And, of course, a pair could be used in parallel for a little more “oomph.” Maynard
  11. Yes, the alternate grounding scheme may be of some use although this amp is dead silent in every system in which it has been tried. The Millie is quite a contrast to the SET monster you posted the picture of! Good to have you on here Nick! Maynard

    Old eyes

    Is your wife still using post surgery drops? They can sometimes worsen an existing dry eye condition. Did the ophthalmologist recommend a trial with cyclosporine? The latter is often very helpful in dry eye patients. Maynard
  13. Mixing brands is fine. With intermittent tube problems it is easier to replace the suspect than to try to figure out what is going on. A tube tester rarely picks up such issues. With push-pull stages I recommend replacing the pair and buying from a seller who can match them using a curve tracer. Maynard
  14. Zen, are you saying that the American Academy of Ophthalmology is spreading disinformation? I sincerely hope not. If you believe that a general practitioner knows as much about ocular conditions as an ophthalmologist then I wish you luck! Maynard
  15. Well, if a person who has had corneal grafts develops symptoms and sees their family doc who is clueless and loses their sight as a result I imagine they will be more depressed! Knowing the possibility would likely result in their seeing an ophthalmologist instead and saving their eyes. Maynard
