Need help in identifying model
#1

Good afternoon.
First of all, thank you for approving me into the phorum. 

I have a Philco tabletop radio that is slowly losing its volume. It tunes the station in fine, but I typically have to turn the volume all the way up to hear it. We haven't used the radio in a while (many months) and when I turned it on this time, even at full blast volume, it is like a 1 out of 10 in terms of volume. 

But before I can ask for help, or a schematic, I need to identify the model, which I'm not finding on the outside or inside of the radio. I've attached a couple of pictures (front and back) in hopes that someone can help me identify which model this is. I've gone to the Philco Radio gallery and browsed each of the years, but did not see this particular model.

Thanks in advance.
Dale

Welcome to the Phorum!

Looks like you have the mid-1935 season version of the 84B. (the grill cloth in the photo in the link is not the correct grill cloth)

Thank you very much!

Dale,

80 and 84 are regens, and so need to be brought to the state where they work on the virge of osccilalting. There is usually a trimming cap that does that, often in the back. Also, of course, if it has not been aligned, it needs it too.

Your "throttle condensor" (the aforementioned one) is the #17.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.

just to clarify, when you say the throttle condensor is #17, you're referring to the schematics in this thread and the part labeled #17, correct? Is the throttle condensor a different name for the trimming cap that you mentioned? 

Sorry for the ignorant question. Radio repair is new to me.

I did watch last night the three videos of "Buzz" restoring an old 84. From watching that video I saw that there are two adjusting screws on the back of the chassis that can be used to do the alignment. I'll research that topic and look at doing that. On that video, there was also an antenna adjusting screw near the tuner knob. I'll pull the chassis out and see if my unit has that adjusting screw too, although I'm not sure what it means to adjust the antenna, so I'll have to research that too if my chassis has that piece.

Thanks again.
Dale

Yes. This is the way Philco called this specific trimmer. Look at the text on the left. the first paragraph.

Welcome to the Phorum, Dale! Has this chassis ever been restored in it's recent past? If not, I would strongly recommend replacing all paper caps and any out-of-tolerance resistors. Do not power it up until this is done. These components are inexpensive in comparison to the parts they can take out if they are left in, powered up, and then fail. Lots of help is here for the asking. Don't worry that your questions may sound ignorant ... we were all beginners at one time or another! Take care and BE HEALTHY! Gary
