I don't think I am being righteous and I never alluded to being green.
The simple point I was making is that if a product is not under warranty, its not going to be fixed by the manufacturer for free. If you reckon your amp was not built to merchantable quality, hanging around here griping about it isn't going to help you. Take some action and go to your consumer advocacy authority. If they agree with your assertion then they will help you get a new amp.
What I got from the substantial part of this thread that I have read is......
This model has had a lot of problems. Some involve re-designs, and need a new PWA to fix them.
If you are under warranty, you get it fixed free.
If you are NOT under warranty, you are dirt, and the amp is dirt, and dirt we sweep away..... We don't really want to have anyone fix a non-warranty unit, and we pretend it isn't there.
NOBODY ever made a law that says the manufacturer must act like: "once the unit is out from any warranty we decide to allow, however short it may be, we should not even acknowledge we made the unit, and you shouldn't get parts, we can't fix it, NOBODY can fix it, because we say so".
But many do that, and they have convinced many writing in this thread that such an attitude is "right and proper".... They have many of you convinced that it SHOULD be like that.
LOUD, in common with many companies, has made the "new normal" of product sales feature the idea that once out of warranty, a product is unrepairable, that the company basically won't support it in any way.
This is NOT how it used to be. It is not how it is with cars (yet). It may not be economical to fix some things, but basically telling the customer to throw it away is not how you make friends. It doesn't even make sense.
The basic issues involved that mess things up are:
Made in "chasia"..... (China or somewhere in Asia)
The run is made, and when done extra parts do not exist.... enough is ordered to make the number of units wanted, and that's it. That's how "contract manufacturing" works. If you as teh customer actually order any extra parts (and some do), any serious problem with the unit will burn through them fast, and you are back to "no parts available".
Design errors
Design errors often require a circuit change, and that usually means a new PWA. So no good way to just change a few part values.
Surface mount parts...
The vast majority of technicians have no clue what to do with an "SMT" board except replace it. And, if the SMT parts are small enough or made in certain ways ("402" size parts, some types of IC package), that's kinda reasonable.
BUT.... "804" and "603" size parts, and "SOIC" etc size ICs are replaceable by anyone who can hold a soldering iron steady, if they learn how. And those parts are the most common ones used.
Even if a design change is only a few resistor values, field technicians often cannot make that change on an SMT board... They simply don't know how, and it would be expensive, so the board may get replaced for 3 resistors.
lack of schematics....
Due to SMT boards, lazy manufacturers ASSUME nobody will troubleshoot the boards, so they don't provide schematics, and troubleshooting is extremely hard or impossible to do.
Expense
yes, customers don't really want to pay, and shop owners don't want to spend money attempting a repair that may not work out due to SMT PWAs, etc. Much easier to treat the PWA as a "part" and replace it if it doesn't work. Replacing the PWA or module is MUCH cheaper in labor..... WAY less than component level troubleshooting. but the parts typically are priced high enough to make up the difference....
Pricing
Repair parts, if actually available at all, are often charged for at up to 10 or even 20 times the price they are as-installed in the unit new. And then the shop adds their mark-up. This makes everything silly priced and convinces people to throw away the whole unit when only a small part is bad.
The result is that the user with a bad unit often gets totally reamed, because the unit is bad, and they cannot get it repaired even if they are willing to pay a stupid amount for it, presumably because they like the unit, and it isn't made anymore.
I guess all I can say is..... enjoy the new world..... you'll be in it longer than me.....
