I don't own a 3030 these days so can't experiment myself, but if I was  
faced with this problem and couldn't find the correct Cubic power supply I'd  
investigate alternative switch mode power supplies that could be mounted in  
the same space.
 
The manual states that the supply provides +/-16 Volts, with a lower spec  
limit of +/- 15 Volts, and 8 Volts positive +/- 0.5 Volts, and it should be 
easy  enough to run the receiver from external supplies and measure the 
exact current  drain.
With the specified AC power requirement being 40 watts  max the 8 Volt 
supply can't be rated at more than approximately 5 amps  anyway, which suggests 
that finding a package to fit shouldn't be too  difficult.
 
Conducted noise might be an issue, so some extra filtering could be  
required, but with all the other modules well shielded anyway I suspect radiated  
noise inside the receiver might not be too much of a problem.

I have all  the modules repaired in this unit but it's missing one PS  
module.
