[NLRS] Spare 8877?

[Bill K0AWU]

Hi All

  Well, I am starting to feel the the 8877 in the W6PO amp I bought back in 
Nov may be soft. I have made improvements in the way the amp tunes, but 
the efficency remains low. (45%)

  Anyone have a 8877 for sale that is known good or just in a known 
condition (not dead) at 144MHZ? 

OR

  Anyone have an 8877 144Mhz amp that would be willing to "test" my tube 
in? I hate to go out and buy an unknown tube on E-Bay to find that there is 
something else wrong. But I'm starting to fear the "worse". I could bring the 
tube down for AU03.
