Kenwood TS-520S Blows Fuse
I have a Kenwood TS-520S that keeps blowing the 6 Amp line fuse in it.
My Bias control is set for 60ma idle current, HV is right at 800V SWR under 1.3:1 It tunes up fine and will run a QSO for about 30 Seconds (CW) then POOF the fuse blows. Blows the fuse when operating phone also. One thing I did find is that the running plate current is a little high, seems to be about 270-280ma when transmitting, but I can't find a way to get it lower... adjusting the carrier all the way down has no effect. rig is putting out 100W on 20 meters any tips greatly appreciated Tnx & 73 |
The plate voltage is low which tells me one of the main filter caps is
leaking. It will short and blow the fuse. -- Clif Holland, KA5IPF AVVid Authorized Kenwood and Icom Amateur Service www.avvid.com 1-800-214-5779 "George" wrote in message om...
