Alpha 9500 ships with an import 3cx1500A7.
One needs to pay extra to have the Eimac instead of the import tube.
Now, are ebay medical pulls reliable for a spare 3CPX1500A7?
Any other non-ebay source, please drop me a note. I looked at mgs4u.com
and they do not have any in stock.

Since when is Alpha using an 8877 these days? Ameritron has had
excellent luck with their source, whoever it is.
OTOH Ive had no trouble finding full output MRI pulls or NOS Eimacs
when needed. Just picked up a NIB pair of 3CPX1500's with 1998 date
codes.

I would go with the supplier selling to Alpha. BTW, as a guy who has
tried to sort out buying from inside Red China, it is a vipers'
nest. By the time you test your items, the design will have changed
because you can be sure that the mfg are constantly looking for ways
to make them cheaper, and you know what that means. Why does the
American made tube cost so much more?

Curious to know if anyone has specific knowledge of which of the
Chinese
8877 manufacturers are known for good tubes, and which are not?
I'm referring to names like "Beijing Jenerator", "Kunshan Vic
Electronics", and of course Greenstone - all of whom supply the 8877.
I'm spending a good deal of time researching this, though it's
difficult
to decipher who's the actual manufacturer, and who's the middleman.
I'm currently waiting on receiving a couple of these from Beijing
Jenerator, who I think is a manufacturer, and I will test them
thoroughly once they arrive later this month.
