My Icom 751 is dead , no power output. I checked it with a swr/watt meter conected to a dummy load and also conected to a swr/watt meter to an antenna. I replaced the recieve board and got the receive working great. This rig was given to me by my best friend and its my first HF rig. Can you help, also I could really use a schematic.

Look here for a manual and service manual. Be sure to look way down the page under Manuals in adition to the Icom part.

Why don't you call Scott Malcolm in Toledo, WA Probably one of the better technicians in NW USA to work on classic Icom radios. http://www.angelfire.com/biz2/mts/

Ernie,
Fear not! It is simply a dead battery on the "RAM Unit" memory board. Icom figured the 10 year battery would be time enough to buy another new Icom radio. Unfortunately, it is not as simple as replacing the battery, for the radio is now brain dear. Check this link: http://www.willcoele.com/radio_repair/index.html#MEMORYREPAIR For about 50 bucks it will be as good as new - no, better than new because it will cover 60 meters, and you don't have to send the radio. You pop out a small circuit board and mail it to him.
Good luck and 73. Maybe we'll catch you on the air with my 751.
