[Amps] 4CX1600B

[KL7RA]

Yo 4CX1600B owners

After many years of faithful service, (rode hard, put away wet), my QRO
3k amp "banged" during the WW. Easy repair, the bridge rectifier for the
-160 VDC control grid was shorted. Took longer to replace all the screws 
holding the QRO HFDX-3K amp together then find and repair the problem. 

If this was a 4-1000 in my home brews I would replace the parts and never 
give a second thought to continue using the tube, but as it's a 4CX1600B I 
replaced the tube with a new spare. 

Anyone have a history on this tube? Once they arc are they ready for the 
(as far as I can throw) pitch in the woods?   

I could put it back in the amp and see what happens but next summer after 
the contest season.
