Anyone into Antique Alarm Clock - AM/FM Radio Comboes?

[Inkmo]

Since my little brother is studying to be a horologist, I thought it would be fitting to get him a stylin' old alarm clock radio for Christmas. I've been on ebay, and non functioning radios seem to be a pretty common problem on a lot of old solid state and tube units. If I ePay it, does anyone know a quick place I can get replacement tubes, etc? How hard will it be to fix things on my own in time for the holidays? Lastly, if this isn't asking to much, do any of you guys know other good places to shop for vintage clock radios, or do any of you have some pieces you might be willing to sell a guy who waited too late to do his Christmas shopping?

Thanks in advance if you've read this far ^_^.
