Weird Version of an Emerson 882 Clock Radio
My parents had a clock radio similar to this one while I was growing up, but I can't find a model number for this. I got it at a fire sale, and when I got it, there was all kinds of smoke damage.
Someone seems to have done some mods to it, but I don't have a clue when it comes to actual electronics. I did a fairly good cosmetic restoration on the case Here's some pages from SAMS But I dunno if it's safe to plug in. What's the general consensus? (I thought I had inserted some images from Audiokarma, but I must have done something wrong.

Can you attach your actual images here instead of linking to Audio Karma?

Got an outlet controlled by a wall switch? Plug it into that with the switch off and flip it on...Worst case scenario you trip the house breaker and have a bit of smoke(may be good to run an extension cord outside if you don't like smoke). Flip it off (the switch! ) if you notice signs of trouble.
Most tube clock radios were series string. Unless the clock motor or power wires shorted there is not much danger plugging them in, any major fault in the radio section will usually at worst burn out the power rectifier tube, another tube or some easily obtained part. You will probably need to replace the electrolytic and paper caps for it to work correctly. (if the lytics are badly shorted that may kill the power rectifier tube.)

As to plugging it in , sure , it's your basic "AA5" that parts are more than plentiful for , and the worst it's likely to do will be to have a loud buzz or hum sound from the speaker . Since that replacement for C1 (the power supply's "filter capacitor") looks kinda old itself it may give the hum I mentioned , or then again it just may work , and throwing the juice to it is as Electronic Memory said , really only a risk to the common as dirt 35W4 power supply rectifier tube .

The reason I call it a "weird version" is that unlike the one my parents had (you can kind of see it in this picture), this one has no snooze bar on top nor does it have the orange indicator light most similar models have. I initially got this as a present for my mom, but until I know it's safe, or figure a way to make it safe, I don't want to risk giving it to her.

Sure it can be made safe , or let's just say as safe as it was when it left the factory back in 1958 . At the minimum , the big capacitor soldered to the speaker has to go , as well as any other "wax paper" type capacitors (this includes any "Bumblebees" that may be lurking about) . Since you said "I don't have a clue when it comes to actual electronics" my best suggestion here for you is this ;
Since this is obviously an "heirloom" piece for you because your not likely to find another as close to your family's original radio as this one you've now found , put it away for a bit , pick up some other ( or two or three) "AA5" tube radios and learn how to do a "recap" on them as your learning experience . You'll of course need to learn how to solder , no biggie there , millions of folks can do it and so can you . A search here of "recap" will turn up all kinds of great reading and although it may seem daunting now , you've chosen one of the easiest sets to repair to fall in love with , the five tube "All American 5" being one of the most simple designs . I will show you a picture of some recent capacitors I replaced , these are mounted to a proper terminal strip and are 105c temperature rated . In your case , where you have a circuit board , there is no reason why some new capacitors couldn't be soldered back onto the board in the spot that the original (C1) was . |

Is it true that the insulation on the wires is Asbestos? If it is, should they be replaced too? What would the modern equivalent be?

I never went through this ritual. I've been working on this stuff long before many of you were a gleem in your father's eye. It's too bad it isn't a little cleaner example of the set. This one has to be totally disassembled to be detailed properly. BTW, that radio is too new to have asbestos wiring. |

The original caps were lousy, didn't last very long. |

Some manufacturers used an asbestos pad above the 50C5 tube, as it runs so hot and could discolor the plastic cabinet. If you run into that type of insulation in a cabinet, soak it down thoroughly with dish detergent and scrape it carefully as not to get the fibers airbourn. |
