Hello fellow virus fighters, hope you are all doing well.
I am working on an Admiral 7T15/5K1 radio that will lose and regain reception on the bottom half of the AM dial. The details are as follows: I can tune to stations above the middle of the dial without any problems at all. The lower half of the dial below 860 kc is difficult to lock on to a station but when I do it is loud and clear. The problem is the slightest tap or movement of the radio will kick it off the station and will also kick it back on.
I can just tap my finger on the table the radio is sitting on and it will go back to the tuned station or it will lose the station by doing the same thing. Does any one know why this is happening?
The radio has had the electrolytics C9a and C9b replaced by the previous owner with two 100 mf capacitors. There is no hum so I'm good with leaving them as is. The paper capacitors look untouched with no signs of leaking wax or rupture. Will change these if they may be the problem.
The two IF transformers/coils have electrical tape on the wires , so I think they may have been tampered with.
I look forward to hearing anyone's wisdom on the subject.
Best regards,
Vince Cappuccitti
