[Kenwood] TL-922 problem , please see the video ...

[Allan]

Hi Gordon and all,

Thanks for your help.


I just check the tube and it looks like ok, not shorted. (just test the pin
with a multimeter )

But I find a smell resistor R22 4.7kohms and the choke coil L7 470uH near
the tube. You can see photo here :

Maybe that can give you a way ..

Many thanks in advance

Regards

Allan

  It appears the Tube is shorting internally but hard to tell from the 
bottom view.
Check the grid caps and chokes on the bottom of the tube socket to be 
sure they have not cracked also.
