RE: AR SP-9 tube question

If you have to send it to a tech, have the coupling and output caps upgraded (I used Vcaps in my SP14) . The tubes in the SP9 are for the phono stage, if that is important to you use the best you can find (think Amperex, Telefunken, or Seimens). If you use it as a line stage only then use Sovtec. These preamps respond to a high end fuse (I didn't believe it until I heard it) and a better power cable.
Maybe your little problem will get you a better preamp.
