Need help restoring my 40-180 - SUCCESS

All caps have been changed with the exception of a mica block at the point of AC input. There is one original resistor left in the chassis. Somehow it got skipped or was not on the official parts list when I ordered my replacements. The resistors that I did remove were all very close to spec - within 5-10%. I will measure this one and see about a replacement. The original caps were consistently 50-60% above spec.
The most obvious starting place seems to be the remaining tubes. I know someone with a tube tester that I might be able to impose on for a few tests. Is there a particular tube tester or set of testers that would be most helpful for me to purchase?
