I was able to locate a tube/valve for my old Tek 561A before I sold it and luckily
my solid state 454 and 453 have been chugging along fine. Of course I use these for
more than computer work so they work as a general purpose scope very well. When
it's time to trace that tricky signal the HP digital comes out. Luckily all I
needed for it was a cable which I found after 3 months of searching different
sources. Of all places - eBay. The seller had his difital scope stolen but they
left the accessories. You better believe I asked what the serial was of his stolen
unti to make sure that it wasn't mine.

for originals
or copies is the tricky part. Many tubes(valves) are still
available new as NOS or rebuilds or newly made. I even have problems on a new
digital scope finding some things from HP.
It never fails to amaze me that I can get spare valves for a unit made 50
years ago (or more), but can't get a new ASIC for a machine made 5 years
ago....
Sad but true...
