There are no-clean fluxes that definitely cause no probs in twenty-odd years
that I have observed them. And water wash ones too. BUT they need very
'fresh' components for them to be OK in manufacturing. [Speaking from
experience in an electronics factory].

There are two types of solder flux. The old rosin-core flux is inert.
The newer organic flux is corrosive and would result in the sort of damage
described in this clock. It needs to be washed off in hot water soon after
use.

The solder flux won't do anything untoward in my experience. I still
have amplifiers I put together over 25 years ago without cleaning the
flux off them and they work fine...if it bothers you so much, take the
tubes out and the PCB from the case and get an old toothbrush, some
isopropyl alcohol and gently scrub the stuff away and wash with fresh
isopropyl alcohol afterwards. It'll take a few go's to get it nice and
clean.
