I just received an ICBM-1 on ebay (used) but it came without a power supply. Can I just get a generic 15v 300ma generic transformer from Radio Shack?

Likewise, I have an ICBM and lost the 15V 300 ma power supply. Where can I get a replacement? I stopped using the ICBM because there is a microphonic-like background hum, so I wonder is the source of the microphonic is from the power supply or is there a bad component (cap resistor etc) in the device? It sounds more like the microphonic background noise of tube gear. The hum is definitely not a ground loop.

I've been looking for a power supply. While very easy to find DC power supplies, this one is AC. Any idea if Outlaw still carries them?
