i changed all final,s & reg. ...............it only dead keys 3 watts & mod. to 4 watts.......what could be wrong... a bad new final?.......puzzling to me.
hi, i was hoping you could help me with this ....... i have a realistic navaho 490- ssb-am 40 channel base or moble....it only dead keys 3 watts & swings 4 watts.....it did more than that before.......what can i do to it ...its a great radio........have replaced some finals...but no help...but...
ok,i,ll try that.but how do i adjust the screw on the bottom? looks like it may go to the final tubes?...its a bright shiny screw thats adjust in or out....what does that do?
it shows to be puting out a lot more on hi side on my watt meter ,but to other people it makes me show less on hi than on low,,,i think it needs to be matched out on the bottom,,i dont have a dummy load,,,,or even know how to match it out ,,,i do know a little about eletronics,,,,and high volts.....
i can,t hear it ,,,,,,,,only on hi power i think ,does more out put on low power than hi power, but only crikit sound on trans. when i key up on hi side ,,,,,,,,like its not matched out or something,,,,,,
YES,,,I CHECKED ALL TUBES ON A TESTER& ALL WERE GOOD BUT 1 & REPLACED IT WITH A NEW 1 ,BUT STILL HAVE CREKIT SOUND,BUT DID NOT CHECK THE KEYING TUBE..........
HOPE SOMEONE CAN HELP ME WITH THIS,,,,,,12 TUBER PHANTOM ,, WHEN I KEY UP , IT SOUNDS LIKE CRICKETS, THINKING IT MAY BE THE KEYING TUBE. A LOT OF PEOPLE HAVE LOOKED @ IT & CAN,T SEEM TO FIND OUT WHAT IT IS ,,,,,,,ANY HELP PLEASE,,THANKS
