Tube Radio
Super Member
I have this tuner with the LK-72A amp http://www.audiokarma.org/forums/showthread.php?p=1827453#post1827453. I replaced the tubes and all paper caps. I am planning on replacing all the resistors as well. The tuner works great off a simple wire antenna. I do not plan on replacing the ceramic disc caps or mica caps since they are good and since some of them are temperature compensated. Even though this tuner has no AFC it stays rock solid on frequency.
