  1. For spare parts see if you can get one on e-bay at a low price and use it for a parts donor', Knobs, and other parts

    Tube amp

    Any quality electrolytic that meets the design spec is fine. Agree
  3. Chicken Or did they upgrade the simulator software for Rattler ? Kangaroo and Alligator are definitely not chicken. Haven't made it to snakes and bugs yet....... Can't wait for the roach burgers they want to feed us.
  4. Necessity is the mother of invention My understanding is that the OTL was born by no copper available during WW2, it was all diverted to weapons manufacturing. Lots of OTL radios produced. Solid State power supplies and regulators make a lot of sense from both price and performance, anything else is gravy.
  5. Thought the first one (yellow) was a Diamond Back Rattle Snake.....
  6. To me the easy real estate in tube amps is the power supply, changing over to solid state. As to output, simpler is better. Especially if 2 Watts is ear splitting on your speakers. Certainly tube designs can be hot rodded for more output, for direct radiators. I understand there is some debate as to the best way to wire up the tubes, I'm guessing that there were dissertations written on them during the 40s-60s. Each likely produces it's own set of trade offs. On a personal note, I wish I knew enough not to electrocute myself, set the unit on fire, or burn the house down.....but I require supervision.
  7. Tube tech probably plateaued in the 1940s-50s Analog plateaued in the 70-80s Microprocessors are about to plateau, if they haven't already. Speed and spacing being the limiting factors. Quantum processing....... we'll see AI just a pipe dream ? I'm still running with my flip phone and 1980s analog stereo, and I worked in high tech....
  8. If you really want one, there are builders who will make one for you Custom wound transformers if needed Would probably want to build a simulation in spice first Also a lot of the current designs, are just updated old tube designs
  9. I have some beat up records I can play when I am longing for pops and clicks....
  10. Another Great Vinyl Mastering video Different information 80%, than the previous video Great explanation of Loudness Wars driven by Streaming Playlists. Again we hear, Vinyl receives the best treatment by the Engineer for Listening Quality. Too bad he wasn't doing something with female voice... See if you can spot his monitors, I can't.
  11. What do TX Blue Indigo Snakes eat for Lunch ? Rattlesnakes Protected Species, so they all don't get turned into boots
  12. Interesting recent (not 1950s info movie) on record mastering and production tips for artists who want to distribute on vinyl. Which is the rage these days. https://www.youtube.com/watch?v=KCYar3q5JH4
  13. Reduce friction, drag, on the needle which may show up as noise. You could also argue it reduces wear on a record. I'm interested to experiment. From reading the articles on PVC and record making, there is lubricant added to the PVC used in records, for mold release, but it does remain on or in the record. Cleaning may eliminate the lubricant.. Thus need to replace it
  14. Dupont NO stick liquid $5 appears to be a dry teflon coating that could be applied to the stylus Might be an interesting experiment with an old, but usable stylus Teflon coat the stylus Silicone coat the LPs
  15. DuPont Teflon Silicone Lubricant Squeeze Bottle, 4 Oz. Material Blend Brand DuPont Liquid Volume 4 Fluid Ounces About this item A clean, light-duty product, DuPont Silicone Lubricant with Teflon Fluoropolymer is excellent for non-metal materials that may be damaged by conventional lubricants Waterproofs, protects, lubricates and preserves For use on rubber, plastic, vinyl, leather, metal and wood Eliminates squeaking and binding in windows, hinges, locks, etc. Helps prevent rust, oxidation and corrosion on all metals Protects fishing gear, tools and farm equipment from salt, chlorine and corrosives https://www.amazon.com/DuPont-Teflon-Silicone-Lubricant-Squeeze/dp/B00BCVXUVM/ref=asc_df_B00BCVXUVM?tag=bingshoppinga-20&linkCode=df0&hvadid=80470559180642&hvnetw=o&hvqmt=e&hvbmt=be&hvdev=c&hvlocint=&hvlocphy=&hvtargid=pla-4584070138368078&psc=1
  16. Brilliant Also leans towards Silicone Is name brand aka Dupont any better than brand x silicone Purity, granularity etc Exactly what properties are we looking for in our Silicone ?
  17. Not sure which one, but one of the articles I just read had WD as petrochemical
  18. The holy grail of PVC and Plastic lubrication PDF Silicone is starting to look like a winner Anyone out there who can do a bake off removing and examine the stylus for accumulation of lubricant I'm guessing zero with silicone "Lubricating plastic gears and bearings, even “no-lube” plastics, boosts part performance and life" https://ecllube.com/resources-for-engineers/tutorials/ECL_Tips on Lubricating Plastics.pdf
  19. How do you lubricate PVC pipe? Asked By: Leo Oroz | Last Updated: 4th February, 2020 Category: style and fashion makeup and accessories 4.5/5 (3,572 Views . 22 Votes) White Mineral Oil A New Way to Lubricate Rigid PVC. Processors of rigid PVC pipe, window profiles, siding, fencing, and doors can save money and speed compound mixing by using a new grade of white mineral oil as an external lubricant in place of the usual paraffin wax. Click to see full answer Also question is, how do you keep PVC pipes from sticking? your choices: soapy water - will make it easier to assemble and remain hard to dis-assemble. Silicone spray - is a good lubricant to use, since it is fairly non-reactive and effective. Petroleum jelly - this is also good.. but will stick to everything and will get on your hands. Secondly, how do you lubricate plastic threads? Dry graphite lubricant powder used by locksmiths. Rub into both threaded part with cloth. Silicone grease or oil, Krytox if you're rich, or Dow Corning Molykote 55 Oring lube. Also to know, can you use wd40 on PVC pipe? In general, WD-40 is a petroleum based lubricant and will not affect most general use plastics such as PVC, PP, HDPE or ABS. Never use WD-40 on any kind of plastics. Will wd40 hurt PVC? It is safe to use on metal, rubber, wood and plastic. It can also be applied to painted metal surfaces without harming the paint. Polycarbonate and clear polystyrene plastic are among the few surfaces on which to avoid using a petroleum-based product like WD-40 Multi-Use Product. https://findanyanswer.com/how-do-you-lubricate-pvc-pipe#:~:text=Silicone grease or oil%2C Krytox if you're rich%2C,Never use WD-40 on any kind of plastics.
  20. Without removing the stylus it will be hard to examine the stylus to see if the WD transfers off of the record WD is one of the great inventions of our time along with CRC Let us know what you discover I can say that my cleaning method with dish soap and micro fiber does a great job, does it reduce lubricants from the vinyl manufacturing process, maybe....
  21. Mobile Fidelity says zero on lubing the records nor offers any product that claims to do so. https://mofi.com/collections/vinyl
  22. Record lubricators & preservatives I recently was introduced to GroOove Lube, a spray-on treatment for preserving vinyl record fidelity. Given the claim that the effect of treating a record is “stunning”, what would it do for my records? Would I get the quieter background and increased depth and detail? I applied it as per the instructions to a very familiar disc that was newly washed. Would it sound different to the many times I’ve previously heard it untreated? Yes indeed! Greater vitality is how I feel describes the music emanating from the playing of a newly washed and lubed record. This seems miraculous and I wasn’t really anticipating any effect to be so startlingly discernable. It’s too early to know the long-term effects of GroOove Lube, but I liken it to Sound Guard record preservative, a similar product that was promoted by a British hifi magazine in the early 1980s (HiFi Sound, I think). This was derived from lubrication technology developed by Ball Corporation for NASA, and worked by lubricating the vinyl and thus reducing stylus wear and static charge on the groove surface. I applied that to quite a few of my records in 1981 (I wrote the date on the sleeves), simply spraying it onto the surface of each record and then buffing it lightly. These records remain some of the shiniest, quietest, and crispest sounding in my collection, and for the large part having never been washed or re-treated. Other products I’ve seen, but are also not readily available in retailers, only by mail order (from the USA), are Milty Permostat and Permaclean, Gruv Glide, and LAST record preservative. Gruv Glide is an aerosol application claimed to improve sound quality. LAST is an archiving preservative that is claimed to “chemically enhance the molecular stability of the vinyl surface”. https://hifiauditions.wordpress.com/2016/04/02/record-lubricators-preservatives/
  23. For audiophiles out there that want a fast and reliable method of cleaning your vinyl record, you’re in the right place. Here’s how you use WD-40: 1.Spray the WD-40 on a lint-free cloth 2.Thoroughly clean the vinyl record with the sprayed cloth 3.Let it sit and dry for a couple of 3-4 minutes. 4.You’re done! https://vacationvinyl.com/how-to-properly-use-wd-40-to-clean-vinyl-records/#:~:text=WD-40 removes any dust%2C dirt%2C grime%2C or unwanted,deem it controversial%2C but WD-40 does the job.
