[TenTec] Titan III Blowing Line Fuses

[Bernie Skoch]

I left my Titan III 417 on stand-by last night.


When I came in the shack this morning and flipped the "STANDY/OPERATE" switch to OPERATE, the amp shut down.  When I fired it back up again the line fuse blew.



I've pulled the HV rectifier board and see nothing unusual (I ohmed out the diodes and checked the capacitors for shorts).  I also ohmed out the input connector and get a resistance of about 3 megs, so I'm doubting a shorted diode or capacitor there.


My next step is to pull the tubes, I suppose, and check for shorts there.


Anyone have any experience with this symptom?


73 and thanks.


Happy 2018, everyone.
