|This is a beautiful set that I bought recently on eBay from someone who has become a great friend (Thanks
When I received it, it was already in very good condition and needed very
little work. With some light dusting and a Pledge Wipe, the
shine returned to the beautiful finish.
||After thoroughly dusting the chassis, re-forming all of its
electrolytic capacitors and testing a 10% statistical sample of all
resistors and paper capacitors, I discovered that the
set was in even better condition than I had expected. I then took
resistance measurements for comparison to the chart in the Sams folder for
the electrically-identical Fada model 799 (since Sams never issued a
folder for this set). Replacing a
few weak tubes, I connected a Variac, an ammeter, some DC voltmeters, a
high-voltage probe and an oscilloscope. After taking some
measurements and evaluating some key waveforms, I checked the RF and IF
response curves against the Fada alignment data and determined that the
chassis was ready for reassembly.
|Here is the set, reassembled with its picture tube and being
tested live. It looks like all it needs are its final adjustments
(yoke, focus coil and ion trap positions, width, height, linearity) to
produce good picture. The picture is actually looking surprisingly
good for a 100% original set at the ripe old age of 53 years even before
||After final assembly and adjustments...powered down for the
moment to show off the beauty of the cabinet. This is a great piece
|This set is a 1949 model, but the dial starts with Channel 1
and ends with Channel 13. History lesson -- Channel 1 was
dropped in 1948. This was one of the last 13-channel sets to be
produced. It's an early-production 9-408, serial number 273.
||Here's the set once again with power on and working very
well. The camera's flash brings out the beauty of the wood, but
isn't very flattering to the picture.
Overall, though, it's a well-preserved antique in remarkably fine original
condition. This case proves that restoring vintage electronics
doesn't always require mass replacement of components.

original rear cover, high-voltage cage and NOS exact-replacement power cord.
