Here's something someone might be interested in. The seller describes: "I'm not really sure what this is. It was found at an estate sale.U haven't tested it but I'll guarantee that it's in good working condition."

$40

These are identical to what the LPB AM-100s used for power. I presume this would be a regulated power supply, though I see no adjustments, but its built specific for part 15 AM, so I erhaps preffered to power something like a Rangemaster or Procaster from 110v.
- Just thought it interesting enough for a mention
Fixed 16 volts and only 100mA max. May only be good for some things. That 100mA is not enough. Seller just picked this up at from somewhere and knows nothing about it. But it says accepts returns.
