I have a Realistic STA-78 AM/FM Stereo receiver I recently rescued from my grandmother's attic. It hadn't been played in a while, but it appears everything is in working order except the FM dial. It's an old-style scrolling dial, and receives FM stations but the signal is shifted by +1.4 to 1.5 Mhz. The AM stations are fine, with no noticeable offset.
Anybody have any suggestions for a fix?
update: It appears the stations are becoming more accurate over time.
update 2: Originally I had plugged in some small FM wires to the base of the radio, even though it has a built-in antenna. Like previously mentioned, the FM slowly corrected itself with those FM wires. But I recently started having problems with the AM, where it would either only come out of the right speaker, or if it would come out of the left speaker, it was extremely quiet. Additionally, the AM stations were shifted over. In an effort to rectify the problem, I unplugged the FM tuner wires. Now, the AM works perfectly fine, but the AM is again shifted up, about the same amount as it was originally (a little less now, closer to 1.3 Mhz up from usual). As Nate said, it could be capacitors. I'll have it checked soon to see if that's a problem. In the mean time, any other ideas as to the cause? Thanks
