Hi,Dave
Maybe you are right.But maybe you don't know, No manufacturer are 100% good
or bad.
In same factory,some products are ver good but the others are very bad, and
in another factory.
maybe it is opposite . The reason have two:the first:,the craftsmanship,
Chinese still like child just graduated from elementary school in idustrial
ability ,although he can built a spaceship and nuke.The second,the price, the
second,Price, your importers often ask our manufacturers,"cheaper and cheaper",
There are morethan 5 tube manufacturers in China, the competition eachother
are intensification. They have to use inexpensive material and use un-skilled
workers.

Hi Hsu - yes, most things are made in China these days :-) But the
problem is knowing which tubes are good and which ones are no good. In my
experience price isn't usually an indicator. Like everywhere China has good
and bad manufacturers. Our problem here is knowing which we're dealing with!
I bought some Chinese 572Bs which were great, some 3-500Zs which were
great, but also some 3-500Zs which were rubbish. But they all cost about the
same.
I think that although by and large in this world you get what you pay
for, various importers play dirty tricks like passing off cheaper, poor quality
kit as good quality. The suppliers and producers come and go, so we don't have
the same sense of stability, trust and guarantee that we do with established
suppliers.
If Eimac (or GE, or GM, or Marks and Spencer....) chose a bad supplier
in China, they'd put their reputation on the line and their name would be
dragged through the mud, especially on this forum! We don't have that
answerability from a supplier we can't identify. Perhaps you do!
As a long-established, trusted and respected company with whom I've
had a relationship for some years now, I know who to speak to in Eimac for
applicaitons advice, who to bounce ideas off, who to get literature from,
including reprints of application bullein and amateur service newsletters
articles up to 40 years old (for example the AS53 design considerations article
I sent out on PDF to this group recently. It's the same people I first dealt
with 20 years ago - and that means a lot. That AS53 pdf was pulled out of the
library for me, scanned and sent out to me in half an hour, because I have the
right network. That's called service and is, I suppose, part of what we pay fo
in the price. They know that, even though I'm just a low budget Ham operator
who buys second-hand tubes and I never paid a cent directly to Eimac.
Sure, Eimac have to source in China these days to remain remotely
competitive, who doesn't? But I know someone who's a buyer of electrical
goods for a major UK chain of retailers. He spends 75 percent of his life in
China and he has to put a tremendous effort into doing that
relationship-building, commercial contracting, pipeline management and quality
assurance - all to actually turn in a profit in a tougheconomic climate. If
Eimac (or another firm I trust) do that on my behalf then I may regard it as a
price worth paying - I know how bloody hard my friend works, how pissed off and
frustrated he gets, and that's worth a few bucks to me!
kind regards
