Very cool. Yes, the Jet may have given you the answer, Radioshack has a parts listing for a BLT71 for one of their phone. If you take the listing to a radioshack store they can order through their internal product repair parts if they still have them in stock. Here's a listing you can take,

... but ya know ... I be tempted to send it back to spylinker for a new one. The unit cost over $120, it'll cost you less than 10 to ship it back and get a new one. Spylinker is very flexible if you want to change to a different unit I fried my 800mw unit and he agreed to take it back at cost and I'll pay the upgrade to a 1500mw unit. Good luck either way.
