I would to see data on failure rates of Chinese tubes. My personal
experiences over the past 15 yrs or so with them have been 100%
positive. 3-500, 572B, and two 8877, all Chinese. I have no objective
data to suggest they are sub-standard. Also look at the Ebay feedback
for the one supplier of 572bs, very impressive. I think the name of the
company on Ebay is "Q-mart" or something similar.

Should I go into my log and delete the 10,000 or so QSO's I have made
with my Chinese 8877 and do it again with a "real" tube?

## yes. The chinese ..."real" tube #1, would have given you another
6db.
Chinese "real" tube #2, would have given you another 9db. Chinese real
tubes 1+2 are both $659.00. http://www.rfparts.com/tubetran.html
## Both can be rebuilt. The 8877 is a ..'throwaway' . Chinese
"real"
tubes 1+2 are a huge bang for the buck, no floozy grids. Now that's
good engineering.
Later... Jim VE7RF
