Wards Airline AM/SW
Girlfriend brings me home this radio she got from a second hand store.. (sorry no pic)
A Wards Airline #93WG-555B radio.. Looked pretty untouched. DC powered only. No way am i finding 2 45v batteries (90v total) for this unit... ALL ORIGINAL WARDS TUBES...  Opened it up and discovered someone had tried to run it once, they had cut the batt plug for the filaments (1.5v) so i attached a D battery and didnt see any lights. Removed the tubes and tested them. As i feared ALL 5 tubes are shorted and no filament glow..  Looking around online ad only finding stubby versions of the original tubes 1A7G--1H5G--1N5G(x2)--1C5G.. The originals are tall and slim whereas the newer ones are stubby and the bases dont seem to fit the special shields and socket setup.. Any tubes,schematic and age of this setup would be appreciated... Tube chart showed additional mod#s---62-555 and 62-2555 Thanks SR

Try this schematic on Nostalgia Air for the 62-555:
http://www.nostalgiaair.org/PagesByM...7/M0011597.pdf The 93WG-555B model indicates it is a 1939 model made by Wells-Gardner for Montgomery Ward. To power the set you could either make a power supply that will supply the 1.5V and 90V or you could use a couple of D cells in parallel for the filament supply and 10 9V batteries in series to get the 90V. For the tubes make sure you are looking for the "G" suffix version and not the "GT" suffix version. The "G" version of these battery tubes will be the taller version. You could look through MDB Ventures site and find all the tubes you need. The ones labeled with TT for tall tubular should be what you need: http://www.fourwater.com/stradio/stradio_sr1.htm#1A7-G I have no affiliation with them but have purchased tubes from them a few times and have been very pleased with price, quality, and fast delivery.

That early, those G types were the only 1.5 volt tubes, available. Zenith did the same thing with their early battery operated sets. The radio in question, was also made as a so-called, "portable". Many referred to them as "luggable". A big clumsy thing with less audio output, than the average, six transistor radio. I consider them as an important part as radio history.

On the GT versions of these tubes not being able to see the tubes glow is normal for the 1A7, IN5, and 1H5 tubes. Even in a really dark room seeing them glow is unusual. Also, be careful if you measure the filaments with an ohm meter to be sure your ohm meter does not supply too much Omph for the tubes to handle. One and a half volts with filament currents as low as .05 amps is all that is required for these.

Oh believe me, they are ALL DEAD!!
 Found an equivalent tube in my supply and did a comparison and you can see a glow. ALL tubes are shorted with NO glow no matter the heater setting... Wonder how much voltage they shoved down the 1.5v line? they didnt mess with the 90v side... And oops, my bad,, just an AM model, the dial scale threw me... Thanks for the links folks... SR

The dial scale is probably calibrated in wavelength, as well. Many radios, of that era, used the wavelength scale and were mistaken, to be multi-band. Kilocycles, meters.

Its cool. no offense taken
So sad these tubes ALL got wiped out... ALL ORIGINAL Wards super airline labeled.... Would love to find AIRLINE tubes 1H5G and 1C5G, the others will be covered by shields... SR

I see that the radio has two IF tubes, capacitance coupled. I wonder if it really makes that big of a difference in sensitivity, being capacitance coupled, instead of transformer coupled. There's quite a few firms that did it.

Yeah, i didnt know a table model existed till i saw the schematic
Wonder how fast its gonna consume batteries when the tubes get here? Do they make post-post jumpers for the 9v batteries or is it a matter of a few modified 9v battery clips? I know how to stack them to test it, but it will look silly SR

You can just snap the 9V batteries together in series. Snap the positive of one into the negative of the other, then snap the positive of another into the negative of the 2nd one and repeat with 10 batteries. You will have open terminals at the end of the string. You can take the terminal board from a discarded 9V and cut it in half to make connections to the string. Here's a photo I found on the web to illustrate what I mean.
