asbestos Ex p o su r e and Rad io C ollecting
C an radio collecting be hazardous to your health? Most collectors arc aware ot' the obvious potential dangers. Other than the inevitable damage to your wallet, there are high voltages to contend with as well as sharp metal edges and fragile glass tubes. There has been some concern about possible radiation exposure from the radio itself and ihere may be side effects from the inhalation oflead vapor from solder and fumes from improper handling o f solvents and refimshing products.
However, one potential menace that many col lectors might not be aware o f is asbestos exposure. 1 have encountered many compact sets from the 30s and 40s with a sheet o f asbestos attached under the cabinet top. Apparently this was employed to protect the wood and finish from the excessive heat generated by tubes and other components. More often than not. the asbestos is now deteriorating and crumbling. This is its most dangerous state.
Asbestos is a physical paradox, d isplaying both crystalline and fibrous properties. B eing wa terproof. resistant to decay and chem ical reac tion. and an outstanding insulator o f heat and sound, it has many desirable properties for use in manufacturing. Som e o f these very properties, however, make it potentially harmful.
The small fibers are easily aerosolized and in haled. Once inhaled, they arc not easily cleared
by the respiratory system and can penetrate deep
into the lung and into its outer lining, the pleura
If the exposed person is also a smoker, the po
tential for developing lung cancer is increased
nearly 10 fold
The risk o f asbestos-induced disease is related
to the number o f fibers inhaled and the length o f
exposure can be brief, even less than a month, if
the aerosolized liber density is high. The onset o f
symptoms can be very remote with a lag tim e o f
up to 30 or 40 years following the first exposure.
Mesothelioma, a malignancy o f the pleura often
related to asbestos exposure, slowly encases the
lung and often resutts in a prolonged and painful
demise from asphyxiation.
Avoidance o f this material is the best preven
tion for asbestos-related disease. It would be ad
visable io stay away from sets afflicted with de
teriorating asbestos Any handling o f such radios
should be done wtth extreme care and with
proper protective clothing, including gloves and
an approved respirator. Refrain from any proce
dure that might aerosolize the fibers such as dust
ing with a blow gun. I f you find an asbestos-
tainted set that you "ca n ' t live without," your best
bet is to contact u specialist in asbestos removal
Special thanks to Mr, Odell Williams o f TV
Central, M acon, C A for providing the radio
used for illustration.

This innocent-looking Zenith S-S-319 looks like a great restoration project, but it also holds a potentially harmful secret.
Turning the radio around reveals a badly de composing sheet o f asbestos attached under the top o f the cabinet.

The Early Television Museum
By Steve McVoy
Well, the USA now has a TV museum to rival the M Z T V Museum in Toronto1Steve McVoy has put it together in an amazingly short lime, anti de veloped a very impressive collection that will at tract world-wide interest. Be sure to pul it on your list o f electronic "must see " attractions But now I'm going to turn the column over to Steve himselfand let him tell the story in his own words.--RB
In November o f 2001 the first museum in the United Slates dedicated entirely to early tele vision equipment opened in Colum bus, O hio, It is operated by the Early Television Founda tion, a non-profit organization dedicated to the restoration and preservation o f receivers and camera equipment from the 1920s through the 1950s. O ur collection includes mechanical sets from 1928-32, prewar British and American electronic sets, early postwar British, American, Dutch and French sets, and early color receivers, in addition, we have a small but growing collec tion o f early postwar camera equipment.
History o f the Museum
In 1998 1 sold my cable television business and, wanting to try something new, decided to collect early television receivers. A s a teenager 1 had worked in a television repair shop, and often

worked on early posiwar sets such as the R C A 630.1 began searching Ebay for sets, and within a few days a R C A T R K -1 2 prewar set cam e up. A t that lime 1knew very little about the history o f television, and assumed that the first com mercial sets were made after World W ar Two.
The T R K -12 was in pieces. In fact, there were two partial badly damaged cabinets. The C R T was missing, as was the radio dial frame In the process o f bidding on the set. 1was c-m ailcd by a number o f U .S . television collectors. A s time went on. 1got to know them, and slowly learned something about prewar technology and history.
I located a company that does historically ac curate cabinet restoration, and they began the process o f making one good cabinet out o f the pieces 1 had. 1began the electronic restoration, and discovered that the technology was not too different from what I remembered o f the earlypostwar sets 1had repaired as a teenager. 1began a search for the missing parts, and finally found a C R T (from another collector) and the dial frame (from a R C A radio o f the same era). The set now sits in the lobby o f the museum.
A s I became more familiar w'lth the history o f television. 1 learned o f the development o f me chanical T V in the United States and in Britain, and o f lhe B B C 's broadcasting o f electronic television three years before the T R K - 12 was
introduced. 1purchased an R O D 382R G in England. This set was my in troduction io Briiisb electronic re ceivers It was also missing a number o f parts, bui the cabinet was in better condition than that o f the 1RK-12
In the process o f restoring the R G D . I had to find a way to supply a 405-line signal fu rti. Collectors I met in England supplied me wiih a V C R . which could play back 405 line tapes.
