Thanks to all who offered advice on fixing the loss of filament to one 
of the 3-500Z tubes in the Henry 2K amp.

I put the tubes back in and started to check filament voltage 1st and 
when I stuck the probe into pin #1 on V1, the tube came on. Pulled the 
tubes again and cleaned all the pin holes and clamps then I gently 
squeezed the clamps a little to tighten them some. Put the tubes back in 
and we are working back at full output.

Thanks for all the advice, I have learned quite a bit in last couple 
days by going thru the schematics looking for different circuits in the 
amp, you were all a great help!

73,
