Hi all,

I’m about to embark on my first restoration of a piece of tube based test gear.  It’s an old Heathkit Oscilloscope from the early 70s.  I am looking for recommendations for approaches to tube testing.  Do I seek out  or build a tube tester or just test in circuit.  Anything else that I should look out for, besides the usual concerns about high voltages on the chassis, and old degraded components.
