Fred -

There is a good article on troubleshooting the AC-4 power supply at

http://www89405.temp.w1.com/DrakeArticles/TechTips/PowerSupplyTroubleshooting.htm>

If you determine that the supply is OK, then you can start in on the 
transmitter.  There aren't too many faults in the TR-4 that can blow the power 
supply fuse.  Two most likely are a short on the HV (650V DC) supply line or the 
filament supply line, often at the connector.
