I have very recently done exactly the same thing.
I have recently sold my Orange AD200b valve head with the OBC 410 & 115 speaker cabs.
Great sound but became toooooooo heavy for me to move about , it was really a two man lift as I had flight cases etc.
sad to see it gone but i have picked up an Epifani UL 502 amp and Epifanu UL 410 speaker cab. They are both really light , easy to move by myself and AWESOME sounding . I play a 1978 & 1979 precision and a 2002 5 string stingray with piezo pickup they all sound fantastic and I would recomend looking at the Epifani gear , it is very clear/punchy/natural sounding and can handle anything from the high c from a 6 string bass to the low B string on my stingray with ease.
I am supper pleased with my rig , highly recomended
