1940's TRUETONE radio. Removed radio parts, refinished the wood and hardware. Installed a DVD/RW, modified and installed a Compaq computer chassis. Mounted a 120MM cooling fan where the speaker use to be. The on/off and tuning knobs are now push button controlling on/off functions and reset. Installer yellow LED lights to illuminate the dial face - gives it a nice golden glow like the original. The two small holes above the speaker opening are the power and HD activity lights. Unit has a full size power supply and micro-ATX motherboard and an extra cooling fan in the rear. All modifications were TRIAL and ERROR - measure, measure, cut. The unit was fully functional and I used it daily for a couple of years.
