If you are just after a shiny radio, just remember that collector values is greatly diminished if eurethane is used. All your waterborne finishes are a eurethane, and even many eurethane varnishes are not clearly labeled as to what they are.
If the radio is plastic, which type? If Catalin- getting the radio to working condition is not an issue, other than the Catalin deforms under relatively low heat.
If it is bakelite, was it painted? If so, and that is part of the work that is to be done, the original alkyd finish appearance is not easily reproduced, but the good news is that most people will never notice if the job is done meticulously.
If the radio is just plain bakelite, does it have a noteworthy look to it? Is it something that is rather unique, like a "Mitchell Lullabye", it is probably worth it. But what is a "ballpark" estimate that you have been quoted? You should know what to expect right up front. Any repair that I have done, I have always been up front of what an aproximate might be, and that there may be some contingency issues that might run the cost higher, but if it is just the common ailments, they should be able to give a good approximation of the final cost. Assume bad filter caps, and probably one bad tube, and maybe a bad paper cap. Based on that, you should be able to get a rough estimate before any work begins. If you want reliability, expect to pay a little more to have all of the paper caps replaced, but you should still be able to get a good idea what the approximate final price may be.
To narrow the age a bit, what is the tube lineup? Chances are good that it was made by another company. You can also get an idea of the vintage by the types of tubes in use, for it was not too long of a time difference between a tube's introduction, and the widespread use of the tube.
In the end, if you are going to keep the radio, regardless of valuation, as long as the repair is not exhorbitant, does it really matter what the value of the radio is if in the end- You get a reliable radio that you enjoy having and using.
: Is anyone familiar with Velvatone? I have a radio in my collection that I am thinking of having restored, but cannot find any information about it. I can't even find a model number. It is a small tabletop radio that appears to be 1930s-40s vintage. I don't want to put more into it than it's really worth. Thanks.
