Hi fellow techies, anyone got a circuit for the Kenwood DPX-500 car audio player. I have having trouble getting the VFD display to light up. The VFD power supply delivers +48v DC and 5vAC to the filaments but no display. Filaments measure around 2.2 ohms. Multiplex pulses at the anodes and grids............any clues anyone? Cheers, Renfred. Remove (X) from xrenfred for correct email address...thanks.
