Your statement is a bit laughable.
I live in Europe and when one of my Mesa Titan failed back in 2017, the tech in charge of it gave me a call telling me he didn't know of he could repair the amp as some parts were very hard to find. Especially the power transistors. Some needed to be replaced.
He finally could find them at a very high price but warned me about the fact they would probably be no longer be available very soon.
This thread proves his point.
Feel free to stick to your beliefs but refusing the reality is a recipe to some disappointments. You've been warned.
I recently found an interesting add for a Titan. While I am very very tempted by owning again this great amp, I'll probably won't buy it for the reasons mentioned here.
