[Amps] 8877

[Robert Briggs]

Hi all..I have a new 8877 which has been stored in it's container unused 
for more than 30 years...After all this time I thought I might bring it 
to life if it was considered still useful...The code stamped on the top 
of the tube is Q8.3169..I know I have a couple of others put away as 
well but can't find them as yet..

What procedure's should I use to test it to see if it is any good?
