Buying 8877s could be a crapshoot but the recent (used) tubes I’ve purchased
have been spot on with the descriptions given to me by the sellers. I’ve been
lucky!
I received detailed reports from the sellers that have placed the individual
tubes into an AL1500 amp and provided input/output wattage readings along with
grid readings.
The BEST way of ensuring any ceramic tubes are good is to send them to a
company in Brooksville, Florida that offers testing services. You can contact
them directly or purchase the service on eBay. The idea here is to get a
cooperative seller that is willing to ship the tube(s) there for testing thus
providing both parties a real health report on the tube(s). The service is
fairly economical but the shipping and insurance is a little pricey. Well worth
the peace of mind. If you have a tube seller that isn’t willing to do this,
tell them to take a hike.
I have an Alpha 77 and owned a 9500 as well. Get a good tube plus a spare and
you’ll be good til you croak. The 9500 won’t let you burn up a tube.
My last suggestion is to buy an Eimac tube. They are far superior to the
Chinese tubes in my humble opinion. I try and buy as little Chinese junk as
possible.
Plan C is to buy a brand new Eimac from Richardson. They are at $2300 each.
Otherwise, good used Eimac 8877s range from $600 to $1200 each.
Good Luck

What does the list think of various 8877 sources and their prices? Thinking of
buying a used 9500.
Thanks,
