Whoa friend.
What is the definition of "a beautiful monitor?"
The devil as they say, is in the details. If you wanted a CRT that was burn free, you should have ASKED if the "beautiful monitor" has a burn-free CRT. Otherwise, you are assuming, and you know what happens when you do that.
So take a big breath here. Understand that attacking members is not going to work here - people will just block you.
Asking for help: good.
Providing answers to people who are trying to help you: Good.
Being polite to a fault: good.
Understanding the terms of a sale: Good.
For example, if you buy a board from one of the sellers here, he warranties his work for 2 years. He burns in his boards. And he defines his warranty in his sales offers.
Unless the seller of the CRT offered such statements, your purchase is as-is, where-is. No warranty is expressed or implied.
You are demonstrating something called "buyer's remorse." Taking that out on the seller is just not right.
As I have said, you need to slow down. Take stock of what you have, and what you want. Understand exactly what you are looking for, and then see if you can find it.
For example, I see you looking for another chassis (ironically with the same seller you are not being kind to here.)
What is your intent in this purchase?
Do you intend to:
1. Take your original CRT (which was burn-free, but with focus and color purity issues) and install the chassis on that?
2. Use your new CRT (or another one you have bought,) and transfer the tube to that?
The reason I'm asking is for purity issues and focus issues sometimes those are TUBE related, not chassis related. You have to know what to adjust on the tube to resolve those issues.
So if you buy a chassis under those assumptions, you are likely to end up with another disappointment and more buyer's remorse.
So let's SLOW DOWN here.
What exactly are your plans: Please be specific, and because you have so many things flying around, be very DETAILED in your plans. Perhaps we can find a way to help you without having more drama here.
