      Love this topic. Let me throw in a Theseus monkey wrench for the 21st century. :)
      In the future, we will likely be able to replace sections of ours brains with hardware. Memory itself might be stored and accessed from a hard drive (Internal or external) instead of cells. Seems not much of a jump to imagine also replacing the logic centers with more powerful processors, maybe eventually replacing all of the biological tissue with hardware. The question is, if your brain is now completely synthetic with all the same memories and a more or less unending stream of consciousness/unconsciousness since birth, are you the same person? Or do you die with the last piece of hardware? or somewhere along the way? Sleep tight!

      @@johnpruett6980 This thought experiment will work if we take into account cognitive flexibility. We need to ensure that any synthetic neurons are still capable of adaptability - (making new connections, breaking old connections). If we can ensure that each synthetic neuron can mimic a biological one, AND we gradually replace neurons over time, then we are in the same boat as Theseus and the paradox still applies. One thing becomes different once we are 100% percent synthetic, we no longer have interrupted consciousness (sleeping).

    This is the good one, the one with a transformer. It sounds a lot like a Tweed Champ, with tremolo and a little lower output. It's a perfect apartment dweller's amp. It'll keep the neighbors and the cops out of your hair, and you can still sound good. This is a very nice little rig.
    The other one is the series filament design. It doesn't use a power transformer, and it sounds kind of anemic. It can also electrocute you if you become the path of least resistance to ground. They should probably be avoided.

      ​@@MarkGutierrez, The weirdest "AC-DC" series-string "widowmaker" amplifier design I've ever seen was in a Caliphone portable record player of the type designed for school kids in the 1950's to use. No power transformer, and the input AC was run through a solid state *voltage doubler* made with two selenium diodes! It also had a filament transformer to power a single ended 6L6GC and a 12AX7/7025 preamp tube, and a fairly beefy output transformer. It was housed in an all metal enclosure, with a metal tone arm that probably weighed 5 pounds. I wonder how many school kids got shocked from a device like that! It obviously had safety issues and wasn't worth restoring, But it was worth cannibalizing for the black plate RCA 6L6 and 12AX7 as well as the output and filament transformers.

    Whenever i have to replace parts I like to keep the originals in a box or a bag and label them. At least if the guitar or amp ends up being a ship of Theseus I still have the original parts. Sometimes on the cheaper old guitars like Teiscos the original hardware was bad even when they were new and finding quality replacements is expensive or impossible so I've had to modernize them and in some cases the only original parts are the body and neck. It sucks to lose the originality but it's often the only way to keep it going and functioning. I'd rather give up the originality and have something I can use than a wall hanger or furniture

How wrong I was. This particular Silvertone is in reality, a real genuine 1960s valve amp. That trem tone is lovely.. Begs the question just how important are full size pine or birch ply Speaker enclosures...???

      The open guitar case forms a pretty good "infinite baffle" for the speaker ---- the farther that the soundwaves coming off the front of the speaker have to travel in order to meet and mix with the reverse polarity sound coming off the rear of the speaker , the less out of phase cancelation occurs, and the better it will sound. Cabinet or baffle material does matter but the size of the baffle or cabinet matters more.

    In the case of a ship I think it's the keel, in the case of an amp I think it's the power transformer. Once you replace those parts, you take out the heart, the soul, the essential part that defines the device. An amp is basically a device that uses an input signal to modulate the output of a power transformer, so that's the part that forms the heart of the amp.

    As long as the tube socket doesnt show severe signs of overheating or arcing, you can avoid drilling out the rivets by replacing the individual socket contacts with terminals pulled from another socket. The terminals are held in the socket housing by a divot or trangular flap, and if you squeeze the little bump or flap in the terminal flat with pliers it can be pushed out through the front of the housing. The replacement terminals can be locked into place in the existing socket housing with a 30 to 45 degree sideways twist. PS, if a rectifier socket is burned or shows signs of previous arcing, suspect a bad filter cap.

    I had a situation like this recently, i found a stereo series filament amplifier in the woods basically. It was totally trashed, couldn't even see the chassis through the crust and dirt. I couldn't find out what it came from, and without a schematic or enough of it intact to retrace everything and so little to save i decided I'll use the chassis and anything i can save and at least try to make it visually resemble what it might have been. Even if i could restore it it wouldn't be the same amplifier anyway, so i felt it best to save the few fragments i could to preserve its memory and give it new purpose as a guitar amplifier. It has a pair of 50L6 tubes and a pair of 7025 tubes. It was originally two single ended amps in stereo. But i plan to convert it to a mono amplifier in push pull if i can find a suitable output transformer for such weird output tubes.

    • @goodun2974
      @goodun2974 6 місяців тому

      From a safety standpoint it's probably far more important to add a 1:1 isolation transformer to the input power supply of your series-string amplifier. This type of AC-DC "Widowmaker" amplifier is no longer produced because they violate modern electrical-safety codes: they have a "hot" chassis and can be *deadly*. They are known as "AC-DC" amplifiers because the transformerless design allows them to run off 110 to a 120 Volts DC; even for a few years after WWII some houses in the US were still receiving DC current from their utility company and not AC. You can't simply add a grounded power cord to this type of amplifier in order to make it safe to use; it really needs the Isolation transformer first. Even worse than a "Widowmaker" stereo hifi amplifier is a Widowmaker guitar amp because the strings of the guitar have a 5050 chance of being electrically "hot" depending on which way the plug was inserted into the wall socket. As for the 50L6 tubes, the characteristics are similar to a 6V6 or 6AQ5, so any push-pull transformer designed to work with either of those tubes should work, for 50L6, and since they'll be operating at very relatively low voltage ( approx 150 VDC) and current, you can use the smallest, cheapest output transformer that you can find.
      It's important to note that while the amplifier in case here, which came with the 2 pickup Silvertone, does have a power transformer and isn't all that different from a Fender Champ, the amp-in-case unit that came with the single pickup version of this Silvertone guitar is an AC-DC Widowmaker design, with much lower power output and a much greater chance of giving you a nasty electrical shock.

    I often wonder this when you see people take an old amp, shotgun all the caps even though many may be fine, replace most the resistors and then re-valve it. At that point it’s almost a new amp in an old box. But if they are happy with the sound then that’s all that really matters.

    • @goodun2974
      @goodun2974 6 місяців тому

      Note that the classic records of the 50's, 60's and early to mid 70's were recorded on amplifiers that were new or nearly so, typically less than 10 years old. An amplifier with 50 to 70-year-old components doesn't really reflect how it sounded when it was new! Some people like the sound of an old amp that sounds loose and woolly because it hasn't been serviced; they have the right to like that sound ---- but it's not the sound that the amp was originally designed to deliver. Anyway, the heart and soul of an amplifier is it's transformers; but bad capacitors can kill transformers. A good tech will evaluate the amp and replace not only any currently defective components but slso the components most likely to cause a *catastrophic* failure in the near future. Otherwise it would be like restoring the interior and exterior of a 57 chevy and then driving it around on its original tires, fan belts, and lubricants.

    A couple of comments about amp restoration and the ship of Theseus paradox: first it is important to note that all the guitar playing on those classic records of the 50s and 60's was played on amplifiers that were either new or likely less thsn 10 years old. If somebody likes the tone, the "mojo" of a now 60 or 70-year-old amplifier with dried out, drifted, out of tolerance parts, that's fine, you have the right to "like" it ---- but it doesn't represent how the amplifier sounded when it was new or just a few years old. Secondly, if you look at classic Fender amplifiers in particular, they were designed to be easily repairable as needed, because Leo Fender was a radio repairman! He understood that equipment owned by working musicians would be subjected to a rough and tumble envirinment (beginning with the roughneck dive bars of Bakersfield California) and things would eventually break, and he wanted his designs to be easily understandable and repairable by any reasonably experienced radio-repair guy anywhere in the country. He saw his creations as tools for the working musician, not as static museum pieces that would forever be frozen in time; His products were continually evolving and subject to change, and even within a given model and a given model year there are variations in the circuits as experimentations took place, or perhaps they had to change parts because the usual suppliers ran out and so they relied on the local electronic-supply house for substitute parts. Anything to get that order out on time so that little Johnny can have his Christmas present under the tree that year!
    Anyway the transformers are the heart and soul of an amplifier, and the best way to protect those is to make sure that the filter and other electrolytic capacitors are fresh and new and unlikely to short circuit and blow up a transformer. Eliminate and upgrade the most likely failure points and that amplifier can probably outlast us all. Leaving in any failure-prone component that is decades past it's expected lifetime is like restoring the unterior and exterior of a '57 Chevy and then driving it around with it's original battery, tires, fan belts and lubrication. Nobody does that!

    I'd like to convert mine to three prong, but I don't understand what you're doing. What is that white wire going to? I see the black wire went to the top of the fuse, but it doesn't look like anything is going to the other side of the fuse.

    • @goodun2974
      @goodun2974 6 місяців тому

      If the conversion is done correctly (which it appears to have been in this video), the white neutral wire from the power cord should go directly to one primary wire (black) of the transformer. The black hot wire from the power cord goes through the fuse and the switch before going to the transformer.

  • @goodun2974
    @goodun2974 6 місяців тому +1

    Bolting the terminal strip for the ground wire to the transformer is an absolute no-no electrically and does not meet modern electrical code. The earth ground is supposed to have its own electrical connection that isn't shared with anything else; and in particular, using a transformer mounting bolt or lamination bolt as ground is a bad idea because even Keps nuts with built-in stsr washer tend to work loose from cycles of heat related expansion/contraction as well as vibration from transport and the speaker being played. CBS era Fender used to use transformer bolts as grounds and also bending the terminals nearly flat against the chassis and soldering them to the chassis as well ---- but at this point the nuts are always loose and the additional soldering of the terminals to the chassis is invariably broken. PS, Dont spray tube sockets with Deoxit! The greasy residue it leaves behind will cause problems in the long run and makes it easy for dust particles to stick to the socket which can lead to electrical arcing, especially in humid conditions. Clean tube sockets with alcohol only so that they will be well degreased. If the contacts of a miniature tube socket are badly oxidized or tarnished, work a piece of wound guitar string of 33 to 38 thousandths diameter back and forth in the socket contacts and it will act like a miniature round rasp or file. Retension the contacts as needed with a jeweler's screwdriver or dental pick.
