![]() ![]() ![]() The chassis with the tuning eye tube in the middle of the dial This is a Sears 1940 Silvertone Console radio – an old ad says that it looks like a $100 radio – Grandma Lila Myers had it for many years in a bedroom in the old farmhouse – KA2C came into possession of it about 1975 – later the cabinet was refinished and the grill clothe replaced – more recently a failed resistor that went open was replaced (a common failure mode for vintage carbon resistors) – a small modification was to add a B+ filter choke and additional B+ filter capacitor to reduce AC hum – this radio used an electromagnetic speaker (as opposed to modern permanent magnet speakers) in which the DC speaker magnet winding doubled as a power supply choke and made some modest sacrifice in hum – this design also had 250 volts DC going through one of the speaker coils (not up to modern safety standards!) – with an external antenna and a ground the AM and SW reception is fairly good and the audio is quite good for the vintage – this 1940 radio included an original auxiliary phono input jack for early TV or phonograph selection since the audio subsystem was a significant capability for the day
