My next project, dad's Philco 40-81
#1

Hey everyone,
Just wanted to present my next project, the modest Philco 40-81 portable. Now, I have a lot of other more interesting sets waiting for my attention, but this little guy has a more personal place in my collection.
This little 40-81 was given to my dad for Christmas in 1940 when he was 10 years old. It is complete with even the original Philco identification card with my dads' name and address still attached to the handle! The chassis is in beautiful condition with 3 original Philco tubes in place (the 4th is a Sylvania replacement). Even the original rubber coated wire is still flexible! I don't think that this set has been turned on for over 50 years. I have a picture of this radio sitting next to dad on the running board of my grandpa's 1937 DeSoto when he was sixteen in 1946.
I came across it while cleaning out my grandmas house after she died in 1987 and has been sitting packed away since then.
My dad is now almost 83 and his health is not good, to the point where I'm forced to realize that he probably won't be with us much longer. That got me thinking about this little radio, so I dug it out of hiding. I plan on replacing the caps and resistors, and even though the original wiring is intact, i will probably replace the wiring as well.
I haven't rebuilt a battery set before. I believe that the A voltage is 1 1/2 volts and the B voltage is 90 volts, is that correct? i have a battery eliminator but you should also be able to power it with 9 volt batteries and D cell batteries for the filament voltage, right?
Any input would be greatly appreciated. Thanks!
Kevin
