McIntosh MAC 1900 Solid State AM/FM Stereo Receiver in Fairly Good cosmetic condition. Built August 30, 1976. All controls and lights work. Some scratches and dings on the chassis and the corners of the faceplate (see pics). Not supplied with a dipole FM antenna or the original jumpers that connect pre-amp to amp for each channel. I will ship with the short RCA jumper cables I used for testing. Also, one of the black caps on the push buttons is loose and will be taped to adjacent ones for shipping. When I first started on this project, there was either no, or very little, output from the right channel. I went to work blowing off most of the dust from the various circuit boards, although the FM board could use a little more care, removed them to clean the contacts and swapped them Left to Right. I did this with both the pre-amp and amp modules and the boards checked out fine with all combinations providing output, but from the left side only. Next step was to clean the volume and balance pots along with the selector switch and then apply DeOxit. I was unable to clean the two banks of IsoStat switches that select Stereo, Mono, Tape Monitor etc. After reassembly and powering up, I had clear output from both channels. Volume and balance both tracked smoothly and selector switch was flawless. However, I found that just touching some of the IsoStat switches could cause one or the other channels to drop out. Another light touch and the channel came back. For the most part, however, this thing worked beautifully every time I turned it on over 3-4 days. Very warm sounding and capable of playing loudly. I was only able to listen to FM, AM, and a SONOS player thru the two Tape Inputs. I cant vouch for the phono inputs but I assume they are fine. The FM stage may also need a little tweaking by a qualified tech. I tried to upload a video showing how smoothly every thing was working with music playing, but Ebay nixed that for copyright issues. Its very short but effective and could probably be emailed to any one interested.
