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.
Best,
Kennet
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 a Stromberg Carlson Radio Receiver no. 520L I would love to get this restored…seems to be in good shape….I replaced the power cord and pluged it in …one tube sparked a little then wouldn’t light up after that the rest seem to be ok. Who would I take this to to get it repaired….. I live in North Vernon Indiana.

Hi Brenda, I couldn’t locate a specific antique radio club in Montana, but you might try contacting the Inland Empire Antique Radio Society out of Spokane, WA or one of the Montana Amateur Radio clubs from this listing: http://www.dxzone.com/catalog/Ham_Radio/Clubs/North_America/USA/Montana/

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?
Thanks,
Greg
