scott lk-48 question

i recently aquired a scott lk-48 which at the time was not really working, it had a really loud hum and one channel was all distorted with low output.

i have replace all fo the ceramic caps under the chassis as well as the selenium bridge, the 12 ax7 preamp tubes and the power tubes.

it now works great and sounds fantastic with the exception of a very low level hum. the hum does not get louder as the volume increases and is not very noticable when music is playing.

before this i have been using a 340B that i had gone through by a local tech, in its current condiiton the lk-48 has more umph and a better sound through all registers than the 340B.

if i wanted to get rid of the hum, would i likely7 need to replace/bypass the electrolytics, or could a bad 7199 driver tube be causing hum.

any thoughts would be greatly appreciated, if i should attend to the electrolytics, are the jj 40/20/20/20 cans okay to use?
