Help with mcintosh mr 67

I have aquired a mcintosh mr 67, this tuner sounds flat in stereo, rich and full in mono. There is also a constant tone sound, all tubes light up, the osc-6ab4 appears weak(very little light.) Any and all help would be appreciated in solving this problem.

Hi
Try calling around to a few TV shops and get all the tubes tested. that Stereo demodulator is not the best in any case. If it needs service. Use expert service only. Call MAC and see who they would recommend. I do not think they service Tube tuners anymore..

Good luck
