In 34 years of daily use, I have replaced 1 open 22kohm resistor and 1 pull switch mini pot.

but, but but, it's not capable of 3Ghz and sampling. It must be a useless
instrument.

** Very true.....

But I needed a scope for knock down, drag out service work on all kinds of items from
tube amps to 2kW SMPSs to 1kW linear mosfet power amplifiers.
Plus all the small stuff like condensor mics.
Plus I needed to be able to service it myself with readily available spares.
Plus it must have a mu-metal shield on the tube.

I was able to buy a spare, internal graticule, PDA CRT for it for under $200 - beautiful thing.
Eats the Rigol for breakfast for what I do.
