Anyone know if there is a Russian military surplus direct equivalent
for this tube and if so what is it called. Need a pair for an Alpha 76
2 holer, and where to buy, thanks.

================================================================
Bob;
Svetlana offers their own 3cx800a7. It is a direct replacement for the 
Eimac. I sell tubes, and I have sold many of these Svetlana 3cx800a7 tubes, 
and (knock on wood) I have NEVER had to replace a single one of them. The 
price is anywhere from 50 to $100 less per tube than the Eimac's, not a big 
savings, but it does help some. I am out of them right now, but if you want 
a pair you can find them at many of the tube sites on the internet. I know 
RF Parts carries them and also Surplus Sales of Nebraska comes to mind right 
away.

If you wouldn't mind buying a medical pull, WA8WZG, Tom Whitted sells 
3cpx800aa7 Eimac medical pulls. He has a web site, ( http://www.wa8wzg.com ) 
and offers the 3cxp800a7 medical pulls at $250 each......I think He says all 
of his tubes have been fully tested and he gives them a full, no questions 
ask warranty. He guarantees that each tube will still be at full output when 
you buy it. If you aren't happy just send them back and he will send you 
another tube or a refund.....He is a super nice guy to buy from.

If you aren't in a hurry I may be able to help you find some later on....but 
if you need then now either one of those places will be glad to help you.

One last thing....You may get several emails telling you the Svetlana 
3cx800a7 tubes are not near as good as the Eimac. As I said before I have 
sold many many dozens of the Svetlana tubes, and so far I have NEVER had to 
replace a single Svetlana 3cx800a7. Not selling the same thing in an Eimac 
tube, I cant fairly say that this would be better than the Eimac tube, but 
lets face it does say they cant be any worse. Eimac makes a good 3cx800a7 
tube, but so does Svetlana. There are always going to be people who will 
tell you "Oh I bought a brand new set of those sorry Svetlana 3cx800a7 
tubes, and one of them failed within a months time".....Well, I can counter 
with this...a very close friend of mine bought a brand new amp that had the 
Eimac 3cx800a7 tubes in it, and within 2 months one of those had failed. He 
ask the amp company why the tube failed, and they told him it was just a 
defective tube from the get go, and that they had been having problems with 
the Eimac's, and they were actually having to test a large number of the 
tubes just to get enough to build the amps. The factory told him that the 
last batch of the Eimac's they had received had a 20% failure rate!......So 
who are you going to believe? I think all that goes to prove is that there 
are people with good experiences and people with bad experiences with each 
brand of tube, and likely neither tube is any better or worse than the 
other. As the old wise man use to say...." You Pay;s your money and takes 
your chances"
Now that I have bored you to distraction, I will say:
