  1. Oh, certainly. I was including them in the split bobbin category in my mind.
  2. TY again for confirming even more. One can begin to wonder and question themselves amid the hubbub. Iv'e been quietly promoting split bobbin xfmers (and choke input filters) here for many years. I don't have the knowledge or equipment here to properly test what I assumed to be true. What I understood is extrapolated off of RF amps.
  3. OK then, just checking to be sure. I know you and he are beyond me in this stuff.
  4. Although I do not disagree with these statement, I do not see how this is apropos through the meter long cable from this external power supply to the load. This seems especially true considering that not only are we fighting the lead network IRL, but that there is likely some sort of regulation between this power supply and the load as per your example. Perhaps I am daft, but it would seem to me that an external power supply cannot react at these frequencies. I am sure you know way more than I, and I'd like to understand. Perhaps you are speaking in generalization?
  5. WTF, really... I feel silly for defending him. Ugh.
  6. Not to throw a wrench in the works, but Paul was discussing repairs. I would never risk the whole board to replace one damaged part. In a pinch, two irons removes a resistor or cap. For ICs, saw off the legs with a knife and use some solder wick. For that matter, with boards like Shadder's example, I've just soldered it all by hand with a pair of optivisors.
  7. Do you think there is anything other than mundane parts in those? They are after all simple 60Hz> DC power supplies. Any high frequency regulation capability would largely be negated by the external leads and connections. High frequency (reduced spacing) being one of the advantages of using SMD. Just because you are not aware of them, doesn't mean they do not exist. People fix electronic items everyday. Oh sure, if you are looking for teflon film and foil caps, you will need to order them online. Simple parts with leads such as metal film resistors, film caps and many ICs are stocked items. Seriously, how many of you have had to actually work on this stuff? I live in a metro area of about 400,000 and we have at least one, but there used to be more. We have a lot of industry here in West Michigan, but I doubt that we are an exception. Businesses rely on crap working. Industry does not like to wait. IMO, the whole spiel about SMD vs through hole is a red herring chosen by Mans as an argument tool. I can think of no reason why they would be better in this instance. I am NOT suggesting that either type of part is superior. They both have advantages and disadvantages depending upon the use. I am not looking to argue here, but IMO Mans' declaring BS was BS and just an opportunity to pounce on yet another person he disagrees with. It is sorta sad to see things come to this. This site was at one time a helpful sorta place. These days it is fetid with egos and arrogance. I am not at all pinning that on you Jud.
  8. I'm not talking about Radio Shack. Most every mid sized town has some sort of electronic parts place. Not for audiophiles, but for all sorts of tech repair.
  9. Oh come on. If you aren't experienced enough to know how to remove a through hole part, you probably haven't had to fix much gear. SMD work requires much more precision and prep. As to the parts, here we are talking about resistors, filter caps and some ICs. I likely could get any through hole part here in town today at the local counter.
  10. IIRC, you stated that you wanted this to be like a good watering hole. And so it this a biker bar or the local pub with Bob's niece at the next table drinking a Shirley Temple? Mans is off base here. To begin with, many of the advantages of SMD parts are moot in an external supply such as this. These are low volume hand made PSs. Conversely to Mans' perspective, there are those who seek point to point wiring for all sorts of "audiophile" reasons. Some of those reasons are sound, others perhaps not.
  11. I'd have to agree with Paul on this. If I understand him, he is indicating it being repairable in the field as it should. Sure if a board is open on a bench they would be similar in difficulty. In actually having to troubleshoot and repair an unknown item, through hole parts are much simpler, quicker and easier to source locally.
  12. I completely relate to your last paragraph. It fits me to a tee. Whatever is in my signature is merely my LR stereo and the one that works! LOL Your first two paragraphs baffle me though. I agree there should be some averaging, but there are too many variables for me to be comfortable saying anything concrete about it.
  13. Despite being a crusty old curmudgeon, I like your posts... Perhaps I am one too?
  14. The way you seem to spout BS causes me to wonder if you are running on all cylinders. If you cannot understand how a recording made off a camera and played back via YouTube might not tell the whole story, then there really isn't much common ground to work off of. I imagine we would all love to think that "sleeper cars(gear)" will out perform bespoke high end ones. The truth is that it depends a lot on the actual implementations. I am sure that I am not alone is suspecting that you system is no where near as capable as you make it out to be- regardless of price or how well you have hard soldered your cables.
  15. Yes, with micro fibers. IIRC it was the bottom of the unit. But can you print with that? Just curious. I keep hearing people suggest printing items, but I have often wondered how durable they might be.
