That is pretty poor info IMHO. Any medical pull that I have ever
purchased, tested and resold ( not 3rd hand "told") has been full output.
Consider that the medical industry does not want any more lawsuits than
it already has....the tubes are pulled very early since tube cost is not
important.
There may be an unscrupulous service company out in some backwater area
that will play games or use pulls in 2nd hand equipment...but not any
that I am aware of......sounds like typical 75M swill to me.
BTW, any 8877 or other tube that has sat dormant for a few years should
be burnt-in before applying RF......just common sense.
