1956 Sears 24" Suburbanite Combo
Here's my latest project. It is a Sears 24" Suburbanite TV-Radio-Phonograph. As shown in the 1956 Sears Christmas catalog. Look in the lower left hand corner of page 406. At the time it cost $314.95!
http://www.wishbookweb.com/FB/1956_S...as_Book/#408/z I got the unit last May near Cleveland Ohio and brought it back to Texas. The family I got it from was very nice and I'm sure they will be monitoring this restoration closely. Let's get to a lot of pictures. A lot are self explanatory. The unit was kept in nice shape all these years and was very clean except for the usual but light dust inside. A quick trip to the car wash took care of that dust.

And now the insides. The TV chassis number is 528.51020 and the radio chassis number is 528.48600. BTW, I'm looking for some service data for that radio chassis.
The TV is a 16 tube chassis that uses a transformer only for the tube heaters. Sams 368-14 and Riders Volume 21 page 524 has the service data for the TV. I haven't gotten to removing the record player yet and that will be after the TV and radio are done. The TV uses a 24YP4 picture tube which tested good after a little while burning in.   After the car wash!    Even the HV cage was pretty clean!   I've never have seen this type of tube shield before. They remind me of clam shells.

And now some pictures of the radio chassis. Help me out with some service data for this radio. Thanks.

I have a Sears/Silvertone AM Only Radio and Stereo Record Player Console that uses the same exact radio chassis your combo unit uses, I might have the service info for you.

Today I started on the chassis. I re-stuffed the 3 E-Caps using Nichicon 10,000 hour 105 degree caps. I also replaced the 2 selenium rectifiers with some 1N5408 diodes.
I added 2 fuse holders and a chassis mounted 25W resistor to sub out the Fusistor and mounted 2 other chassis mount resistors. More on those later. Here is a before picture followed by my work today.

Riders didn't list that model number. Bummer. EDIT: catalog number 7053 and 7054 look promising too.

I use the "Presoak" which gives a mild pressured spray, and then to rinse off the chassis I use the "Spot Free" rinse, which again is a mild pressure spray. Then I let it sit in the hot Texas sun for a few hours to dry with a turn over about midway.

I started off today's work by finishing wiring the power input and fusing of the parts that installed yesterday.
Then I went to work by replacing all 11 resistors on the IF board. 5 of them were clearly out of tolerance. Of the remaining 6, 3 were at the high end of their tolerance. I then moved onto some terminal strips and replaced the resistors and film caps as needed. I replaced 1 E-Cap in the audio section V8. I then did V8 and V9 and a few other resistors near them. Included are some before and after pictures.
