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.
