Section 5: ECF80 Driver Board Construction
In this section we will be building the first of the 2 Driver Boards, which contain the ECF80 tube. See the Appendix for the
schematic for this board.
The build of this board is quite straightforward and shouldn’t pose any problems. Just make sure that the three electrolytic
capacitors are inserted the correct way around - observing correct polarity.
SPECIAL NOTE: R12 and R13 have been moved from this board to the Output Board. Therefore, you should replace
these resistors with wire links!
