My amp tech friend says the same, he's 73 and has worked on just about any tube amp you could think of, he also has access to many thousands of tubes and knows where many more are.when the guy selling them says there be a shortage...
i now only buy tubes that have been 100% tested by audiophile freaks who have a world class tube tester and i have never been happier.
used holy grail tubes from yesteryear that are verified good as new cost less than a new untested low dollar new tube.
let him keep his tubes, i don't want or need them.
Spotted this from my Amp Tech
I'll repeat my post from TDPRI:
The Guitar.com article is little more than an attention-grabbing mini rant from Matthews. Shame on Guitar.com for failing to validate anything he said, then piling on their own breathless hyperbole. The only thing they sort of verified is that Shuguang "does seem to have scaled back production enough to spark online rumours." There may be some facts to learn about the situation, but but neither Mike Matthews nor writer Cillian Breathnach provide any.
Perhaps these phrases from the article can be read like poetry:
A perfect storm
Struggling to meet demand
There is a worldwide panic
Fraught with this sort of danger
Could cause prices to rise dramatically
