Filter Capacitor Done & Tuning Coil Replaced

 I replaced the second tuning coil (far right) because the tuning slug was binding in the core. I got a new slug and coil from a chap on the Antique Radio forum.

 Base epoxied. The perferated piece holds the terminals in place.

 New Capacitors soldered in place

Filter capacitor assembled. I epoxied the base in place, epoxied the mounting ring and then crimped over the lip of the can.

Tuner Removal/Clutch Repair

 Tuner removed

 Clutch assembly. One of the rubber clutch discs are flopping around and the outer clutch plate is all rusty.

 Rusty clutch disc and crumbling rubber clutch disc

Broken tuning slug. This is the middle tuning slug, trying to get one from the Antique Radio Forum

Received Radio

I received the radio today.

 Bezel has some pitting in chrome

SM6T is the model number. Need speaker plug.

 Need new power lead wire

 Funny to see the vibrator sticking out

 All tubes present

Labels completely faded away

Lots of grime. This is caused by the power transformer leaking some wax and the dirt sticking to the wax.
Tuning clutch shot
 Looks like some hornet activity behind the dial light

 Peeling paint

Dial glass held in place with speed nuts

Bottom of electrolytic capacitor shows three caps in one. Two are power filtering and one is the output amplifier cathode bypass.

Tuning slug coils will need to be disconnected so that the tuning carriage can be removed. Unless I can remove the clutch without removing the carriage.
