I purchased this decal set for my philco 37-640 floor model but the only one i see that is on any cabinet is the main philco decal. I cant understand why there are no knob decals??? I look them up and not one photo online shows decals on the front to let you know what positions are for the knobs. How would someone know what the knobs and positions were and were for without them? I guess it would be wrong to add them since it is not original... Are there decas i am missing? id still like to know what the positions are on the on off knob. this one has 3 settings 1.on, 2.?, 3. ?
???
Oh and one last thing. What about the switch knob in the middle bottom? what does that do? does it have to be in a certain position to get the radio to play? is that for the shadow meter?
Thanks

Philco did not start using decals to identify the various knobs until the 1939 season. The exceptions to this are the
high end 1937 and 1938 models: 37-690, 37-675, 37-116, 37-9, 37-10, 37-11; 38-690, 38-116, 38-1, 38-2, 38-3. Even these did not have a decal identifying the band switch.
How would you know? The original owners knew because they had the owner's manual. Those owner's manuals were usually tossed out by those same original owners, and few remain.
So how can you know now? Just ask someone here...
The upper middle knob is, obviously, the
tuning knob.
Lower three knobs, left to right:
Off-On-Tone,
Band Switch,
Volume. The off-on-tone control is a multi-position switch instead of a variable control; this is how Philco designed the 37-640 and many other 1937 Philco models.
Band switch: Extreme counterclockwise - Standard Broadcast (AM); second position clockwise - Shortwave (lower band, the scale of which is just above the AM band on your dial); third position clockwise - Shortwave (upper band on your dial).
ok thats good to know, one thing, the on off knob has a 4th position so it is off on tone and ?
what do these tone positions do? I cant seem to get any radio stations to come in, thanks for the prior info.

I moved this thread to Philco Home Radios since it isn't specifically about a cabinet.
The four positions of the off-on-tone control are for four different levels of tone; the tone is supposed to get deeper as the control is switched clockwise.
As for no reception, two questions:
1. Have all paper and electrolytic capacitors been replaced?
2. Do you have a longwire antenna connected (to the far left of the four screws in back)? This can only be five feet or so for testing purposes, but should be much longer for normal use.
I think the last two positions are for tone... treble and bass positions. One has more bass than the other.
Thanks for the info and I know what you are going to say, Dont turn on the radio until the capacitors are replaced. I have not learned to do this yet so i have not. I do have a 6' wire antenna connected but which screw? first is red, second is black, third is ground and 4 is unmarked.sorry to ask when you answered but i am no good with stage right or left....
As for the next questions: I need chassis training, I have been looking all over the getting started pages and found a few books for beginners but not sure which one is best for a complete novice.

I also have this Philco 84 I am restoring the cabinet on. The radio works but not well the bottom looks like a lot of the wax caps were replaced. Should i work on this one first since it is easier looking?

Ok,
that is some stuff to get and lots of reading ahead. I have looked for the books but amazon wanted like $1000.00 for one? I could not believe it. Ill have to keep my eye out unless i find someone here selling one on the for sale topics.
Thanks for the info and I will get started.

I would recommend "Elements of Radio Servicing" by Marcus and Levy, those turn up fairly regularly on fleabay. Another set of books to look out for is Basic Electronics put out by John F. Rider Publications back in the 1950s and 60s, those explain how most tube based circuitry works. Some really good how to videos to follow are the one on You Tube put up by joernone A.K.A Badrestorer, there is a recent series where he restores a really beat up Atwater Kent chassis.

I wish you had posted that earlier. I went on sleezebay and got the 6 volume basic electronics set but it is the wrong one...
Thanks for the links for the right ones. Once I finish some work I will get to reading.
Thanks all,
