*Lance; My machine is way older than the CR series. I saw a picture and PDF file for them and their vintage is newer.The power supply in my unit has a huge heat sink. Mine has N type Tx and Rx connectors coming out of the top of the cabinet, they weren't being used when I got it. The receiver had RG 142U hardwired to the input which ran directly to the cans. I drilled a hole and installed a chassis mount BNC connector and put in a BNC to type "N" jumper in. I also installed a jumper likewise from the Xmitter to the other "N" conector coming out the top. I'll see if my friend can take some photos to send to you so we can indentify it. Hopefully with that info I can obtain some sort of service manual or at least a schematic. I hope you can come up with what I need. I have several other machines on the air even as we speak, but this is my first Johnson, but it was free and I've got too much time on my hands, and a local club needs a repeater so I'll "git 'r' done" and turn it over to them. Thanks. [?] de Lee K4LJP 73* On Fri, Sep 18, 2009 at 1:46 PM, Captainlance <[email protected]>wrote:
