Good afternoon: 

My trusted DX-40 is blowing its fuse. After some initial checks, I have disconnected the HV leads and made the following measurements: Total HV winding resistance: 312 ohms 

Outside-to-ct: 181ohms/344 vac.... 

Outside-to-ct: 131 ohms/274 vac. The ac measurements are made with 60vac at the plug. 

The xfmr gets warm even tho the on time is short. 

  

Would ya say this resistance/ac voltage imbalance would indicate a tranny problem? 

Thanks, 73 de Bill K4JYS
