[TenTec] TT Centurion AMP failure

[Doyle]

Hi Phil,
    Received several responses.  I just put in my old set of 3-500 tubes & 
have the same symptoms 200 Ma plate current in both the stnby/operate 
position.
    Only live 40 miles from TT, will take it over the first of the week.
    Thanks for the reply.

Doyle....

You almost certainly have a grid to cathode short in one of the tubes.
Remove them one at a time and see what happens.
