Schematic preservation
« on: January 03, 2025, 12:40:45 am »
Word on the street is that a certain recently absorbed company, who holds lots of patents and builds things that "chug", is mobilizing to make sure their documents aren't available for download.

Sorry for the alarmist rant but just wanted to give a heads up to anyone who may rely on such information:

First, just a general reminder that sometimes, things *can* disappear off the internet, and its a shame if you ever need something later and can't access it, so maybe make a backup or grab your own set of these while you still can.  But also, in general, it's good practice to store your own copies of things like this that could someday cease to be available - the Internet Archive (Wayback Machine) that plenty of people use to find "lost" website content was hacked recently, making it clear that nothing is guaranteed as far as content availability is concerned.

Ok, I give up, who?

If you mean Trainwreak, it went out when it's founder Ken Fisher passed away.

Mays A Bougie.  Trying to not invoke Beetlejuice directly - seems like they've already had schems taken down on other sites  on request from their legal team.

Oh, he's been doing stuff like that pretty much from the beginning.   :laugh:                                                                             

He put out some schematics that some say were wrong on purpose.
                         
And he's got patents for things he probably shouldn't too. For things that existed before he got it patented. But you have to have enough money to take him to court.

100% - I've heard about those antics for a while now - I think it might be a little different presently because they were absorbed by Gib-sun, who, I'd expect, has a far savvier legal team, with a lot of time on their hands to do things like shake down tube retailer websites for having their incorrect schematics posted for download.  :icon_biggrin:

I have no interest at the moment in building a very cluttered, fizzy, over-gained mess(a?) with 400V caps sneaking in to the "450V and over" party, but I like knowing they're there if I wanted them for some reason.  I saved everything to my growing library of odds-and-ends just to be safe anyway.

There's no love lost for Mesa Boogie . . .  Great amps when they work, but very difficult to repair when they don't.    No support for independent repair folks.   Nothing new here, and the acquisition occurred some years ago in 2021.

I think KKR has owned Gibson since 2018.  Interesting executive team.   I have paid them no attention --

Who is KKR?

People got to stop assuming everybody knows these abbreviations.  :BangHead:    :cussing:

There's a reason we have words, not just the 1st letters of words strung together.    :think1:

The private equity firm Kohlberg Kravis Roberts (KKR) owns Gibson:

Sorry about the abbreviation.   KKR is the financial company that took RJR Nabisco private back in the '80s.  You may have read the book "Barbarians at the Gate" (also a movie) which chronicled the story.  It was a huge deal at the time.

Normally, they buy, restructure and do the usual corporate thing of stripping the assets, slashing jobs, you know the drill.

In Gibson, which is (I think) a small deal for KKR,  they've installed a guitar guy as CEO, who reportedly wants restore the company to glory.   So not the usual scenario.  We will see what they do.

Agree, but "WTF" comes in handy daily for me. Like when I open up the chassis on a mess-o-boogers.

Acronyms sometimes are very annoying, especially rarely used or known ones.

That's the point, that list goes on forever!  :l2:

Growing up we all knew a few, FBI, CIA, IRS, but not many.

But now, it's way out of control. It's like another language, but there's way too many acronyms to memorize. We have several here that we use all the time, PT/OT, R, C, K, vac/vdc, RMS, Hz, Z, etc.

But we're dealing with the same things all the time and with people in the same field.

There are still acronyms in our field that many haven't come across.  The elctronics field is very large and has many subcategories.
It is common in writing for all people to use an object's name first (with the acronym abbreviation following in parenthesis) and then use the acronym later in the text. Can you imagine reading Merlins books if he used acronyms with no explanation as to what they stand for?  Now most of us know the common ones like "k" means cathode, yet some have asked "what does K stand for?". 
Liken it to posting without a schematic.  Same principle. We don't have many schematics memorized so we kindly ask for the OP to include one or a link to one.
It's only courteous to the others here and some acronyms are not common at all. They are rarely used in everyday electronics discussions, those are the ones that can stunt someones effort to understand what is being discussed.
Also consider we have many newcomers here.
Anyways  I'll go now and leave it at that, because   "resistance is futile" .

A company named Komet was supposedly carrying on with Fisher's life work, guess one of the guys there apprenticed or worked with Ken. I have no idea if their company is still in business. I do know their work was impeccable and the amps were expensive.
