If Jan D. says so, I guess a "wall wart" is really good enough 
But I do hate those things, so plan to instead make a good (and simple) linear PS, and put it in a matching case next to the High Octane.
All you need is a 10VA transformer with single 36V secondary, a rectifier and a capacitor or two, for a bit of filtering. Plus of course a fuse holder, an on/off switch and some wire etc, and a box to put it in. Can be build point-to-point, or on a prototype/perf board.
I will probably use a Talema 2x18V, and wire the outputs in series to give 36V. After rectifier and caps, it will give app. 50V DC.
If DC turns out a bit too high, you can scrub 1V by placing a R33 resistor in series on positive side in PS (assuming total power consumption of High Octane to be 30mA). I have used PSU Designer to make a schematic of the basic circuit.
Some might say it is overkill, but I say it's quality

I use the same solution. It happened to have a 2x20v transformer and i installed a 220R (if i remember well) between the two filtering caps in order to lower a bit more the output voltage. As the req power is low enough the disipation on resistor is very low.
My next plan is to install a LM317 after this CRC filter to have a steady 48V on output.
I would avoid a SMPS wallmart adapter.

is Sanyo 2SC2362Kthis a good replacement transistor for 2SC2547?

Oh, I actually really like wall warts.
The old ones have EI-cores with low capacitance between the windings which keeps high frequency line junk out.
In addition they're located far away from the phono circuit which prevents humm pickup.
The high octane comes with a strong regulator which eliminates any poor regulation that might come from the cheap wall wart. Just use an overkill unit with a 0.5-1A rating or so.
