In any event, I am working my way through refurbishing, etc. of several 7000
series scopes as a hobby. My favorites in order best to worst so far are
7844, 7904, 7834,7704A, 7613. Obviously all based on personal opinion and
preferences, etc. I will say however that the 7704A is indeed the easiest
to work on and understand, etc. Indeed if my goal was ease of maintenance
and extended mean time between failures (perceived failures not actual as I
do not have enough historical data for my MTBF to have any meaning).... The
7704A would lead the list...
I was surprised by the simplicity of the 7904 versus the 7834. It was
mostly empty space inside but I should have expected that.
Finally I cannot comment on the 5xx sharpness vs. any of the above examples
( they indeed are all I have experience with) . I will say however one of
I have a 547 and while it is definitely sharper than my 7834, it would
have to compare it side by side with my non-storage oscilloscopes to
see much of a difference.
