I am assembling an ice tube clock kit and have run into a problem with the boost inverter. Where the online instructions say the expected measurement is between 40V and 70V, I only measure 14V. Initially, it was measured at 30V, lower than the documents stipulate, but I continued to populate the board. However, when it came time to install the VFD tube, the tube did not light and I found the boost inverter's output had fallen to the 14V.
The 7805 is regulating to 4.95V from a 9V wall adapter, and the board beeps on power up each time.
As of now, all of the components have been placed in the board with the exception of the tube itself.
Any help with this matter is greatly appreciated,
