Hello, I'm currently working on an externally mint Sears CB model 564 however, I'm to the point that a Sams Manual would really come in handy. It's nearly impossible to find one but my question is: "Does this radio share the circuit board with another model either Sears or otherwise? I'd even be open to the idea of using another service manual for a different model that closely resembles this one like the Sears model 934.36740500. If anyone has any information about this radio or if I can use an alternate Sam's manual I'd greatly appreciate any help.
