  1. Love seeing your wonderful work. I have a General Electric H-116 in great shape and works like a dream. I replaced the magic eye. I would like to tune the buttons to my locale stations. How does one get the information to tune these buttons” Thank you for your time.


    • jwk says:

      Great question. There are two types of pushbutton arrangements: one is a mechanical linkage which physically uses a lever to move the tuning capacitor; another uses an assortment of coils with permanently adjustable capacitors to form tuned circuits for ANT and OSC for each station you wish to have as a preset.

      If pushing the buttons makes the dial move, you’d need to find the manufacturer’s service literature for instructions; it can be somewhat complex. If they’re the electrical preset type, look for a bank of adjustment screws. Usually on the back or behind the pushbuttons themselves. Adjust the OSC screw which tunes the station until you’re receiving what you want; adjust the ANT screw for maximum volume. Often, the tuning range of each button preset is limited due to the coil construction, so some buttons could have stations say 540-1000 and others 1000-1600 for example. Trial and error required.

      Good luck!

    Hi, I have an old Stromberg-Carlson console radio receiver no. 61-N that was given to me years ago not in very good shape, certainly not working but that appears to be all there. Do you think that if I sent you some pictures you could tell me anything about it?
