[Amps] titan 425 dimming, drop in power, hv

[gudguyham at aol.com]

Where there is smoke there is fire.  You should be able to see where the “ hot spot” was.  The only thing I could think of is the step start resistor although that should be out of circuit in seconds after the amp turns on.  You should have a step start fuse and should be either 1.5 amp slo blow or a 4 amp fast blow.  Make sure you don’t have a big fuse there.  Unfortunately the Titan 425 amps are known for shorted transformers as they get older.  I’ve replaced three so far for customers.  Get into the power supply and get your nose to work.

thanks to all who responded to my post on 12-11-17 on this amp problem. i tried to follow every suggestion from all who responded till i got to the filter lytics. was not sure so went ahead and dropped too much $$ on a re-cap kit on ebay. sadly the problem remains. i thought at first i caught a slight smell when the problem occured but dismissed it as the wood stove fumes from next room. this time with new caps installed i ran it a little longer and tried to touch up the tuning. yup, the smell was stronger and i stuck my head under the table to see smoke. i could not kill power, remove the cover and look for the source in time to see it. after voltage safty check felt for hot part but found none. i dont think a rf deck problem is the cause, but not real sure how to proceed finding this. any further ideas will be greatly appreciated. 73 mike Kilowatt Six
